Trigger Ability トリガー能力 (Torigā Nōryoku)
Dmwiki.net:	Article

Trigger Ability is a term given to cards that have an ability that triggers when a specific condition is met.

Details

In the comprehensive game rules, it is described as 誘発型能力 (Triggered Ability).

2 Quixotic Hero Swine Snout
/ Creature Beast Folk 1000+
■ Whenever another creature is put into the battle zone, this creature gets +3000 power until the end of the turn.

2 Propeller Mutant
/ Creature Hedrian 1000
■ When this creature is destroyed, your opponent discards a card at random from his hand.

After the trigger ability meats its condition, the effect is processed. This is known as "Resolution".

Trigger Ability rules

1. A trigger ability can't be resolved during the resolution of other triggered abilities or spells. If a trigger ability occurs during another a spell or other trigger ability, it will until wait until they fully resolved.

Example) if Olzekia, General of Decapitation is put into the battle zone with Savage Earth, you can destroy creatures with the trigger ability of Olzekia after Savage Earth resolves his effect and is put into your graveyard.

2. A trigger ability is resolved after applying each effect from continuous abilities. Creatures that have an static ability that occurs while they are in play have their effects applied first before all other trigger abilities regardless of the order they entered the battle zone.

Example) if you had an Quixotic Hero Swine Snout in the battle zone and summon Funk, Guard of Hope, the continuous ability of Funk resolved first, destroying the Quixotic Hero. While the ability of Quixotic Hero would be due to resolve next, as it is destroyed, the ability doesn't trigger.

3. If 2 trigger abilities were to trigger at the same time, they become pending triggers, and wait to resolve one at a time.

If you have more than 1 trigger ability occur at a time, you may resolve them in any order you prefer. (It doesn't have to be the same order you summoned or cast them.)

Example) When you cast Heaven's Gate and put Milzam, Spirit of Miracles and Emeralda, Pitch Dragon Elemental into the battle zone, you may resolve the Shield Exchange from Emeralda or the Shield Plus by Milzam ability in any order.

4. When one of your opponent's trigger abilities would occur at the same time, the result differs depending on whose turn it is. The active player (who's controlling the current turn) resolves the abilities of cards with a trigger ability first before the other player.

Example) If a Propeller Mutant battles against another copy of itself, both are destroyed. The active player triggers the ability of their Propeller Mutant first.

Example) Say you summon Dark Sanji, Darkfang Ninja while your opponent has a Quixotic Hero Swine Snout in the battle zone, and aim to destroy it with Sanji. Both of these creatures have a trigger ability. If you summoned it during your turn, the ability of reducing a creatures power by -2000 resolves first, destroying Quixotic as it is lowered to -1000 power. However, if it was summoned during your opponent's turn (By Ninja Strike), the ability of Quixotic would resolve first, increasing its power from 1000 to 4000, before then being decreased by the 2000 from Sanji, and preventing its own destruction.

5. If a trigger ability triggers during the resolution of another trigger ability, it is treated as a trigger ability that was triggered at the same time (similar to rule 4). Also, if the trigger ability of the active player triggers during the inactive players resolution of a trigger ability, the trigger ability of the active player is resolved preferentially.

Example) Your opponent has a Magnum, Allshot Puppet in the battle zone. You have a copy of Jin, the Ogre Blade ~Young Leader~ in your hand as well as your mana zone. When you summon Jin into the battle zone, you put the second copy of Jin that was in your mana zone into the battle zone with its trigger ability. When that second copy is put into the battle zone, two trigger abilities occur; the Jin and Magnum.

In this case, the active player resolves their card first and the Come Into Play ability of Jin occurs before Magnum.

Example) You have Truekaiser Adrenaline Max in the battle zone and other creatures. Your opponent has 2 Baradios, Lord of Dragon Spirits in the battle zone. Truekaiser has not yet been tapped this turn, and you break the last of your opponent's shields with one of your other creatures. At this time, the only abilities that trigger are the 2 copies of Baradios. After the first ability triggers which taps your Truekaiser, the ability of Truekaiser can now trigger. As you're the active player, it resolves first and all your dragons are untapped. Then, the second copy of Baladios will have its trigger ability resolve, again tapping each of your creatures.

6. If a trigger ability pending to fit and the target's card type changed before resolving, or is an trigger effect that rendered a creature unable to attack changes its card type after it has resolved, that trigger ability would be reset.

Example) You have an Ira Fizz, Dragon Edge equipped with Proto Gigaheart, Invincible Sword in the battle zone and is evolving into Redzone, Roaring Invasion. At this time, if Mass Removal such as All Delete by your opponent was used, the weapon Proto Gigaheart, Invincible Sword,、the bait Ira Fizz, Dragon Edge、and the top card Redzone, Roaring Invasion would all be targets sent to the deck separately. In response to Redzone, Roaring Invasion leaving the battle zone. Proto Gigaheart, Invincible Sword's substitute effect kicks in and Dragsolutions. Due to the substitution. Redzone, Roaring Invasion is exempt from removal and Ohginga Zero, Strongest Dragon is also exempt from removal due to the change in card type. In the end, on lyIra Fizz, Dragon Edge》 is sent to the deck。

Example) Prin Prin, the Victorious uses her effect on Q.E.D. Plus, Final Dragon Logic, and QED Plus Dragon Evades. (Sword Saint Jigen, Awoken Dragon World) flips QED Plus、and effects such as "cannot attack" are all reset. It could Dragsolution and attack again depending on the situation.

7 If Shield Triggers and Strike Backs are pending with other trigger abilities, they are resolevd before anything else. The active player's effects go first too. If the non-active player has shield triggers that are pending with the active player's trigger effects beside Shield Triggers and Strike Backs, then the non-active player would have the privilege of solving his effects first.

Example) "Mastermind" and Emeralda, Pitch Dragon Elemental, etc.

Other

• Although it involves fairly important rules, it is only briefly mentioned in the rule books and the Duel Masters Official Homepage in the Q/A section of some cards.
• Common Trigger abilities include; Come Into Play ("When you put this creature into the battle zone"), Put Into Graveyard ("when this creature is destroyed") and Attack Trigger ("when[ever] this creature attacks"). As can be seen in the name, Shield Trigger ("when this card is put into your hand from your shield zone") is also a trigger ability. Creatures that have a trigger ability when they leave the battle zone (when this creature leaves the battle zone) were later introduced.
  • An Attack Trigger is shown as "when(ever) this creature attacks, ABILITY". It doesn't occur when the attack is completed, and is instead resolved immediately after declaring an attack.
• It's easy to mistake System Creatures such as Mist Rias, Sonic Guardian or Super Trash Train, Fuuma Devil as a trigger ability, but they are a Static Ability as they continue to generate abilities while they are in the battle zone.
• A triggered ability is always triggered after the event occurs. For this reason, an effect always resolves after the event that the trigger condition was completed. Ex: If you destroy Pharzi, the Oracle by the effect of Dark Soul Creation, the effect of Dark Soul Creation resolves, is put into your graveyard, and you may then resolve the Put Into Graveyard trigger of the destroyed Pharzi.

Interactions with other abilities

• Power Attacker is not a trigger ability. It is a continuous ability on a creature that affects the creatures power for the duration of the attack.
• If it is a trigger ability that starts a substitution effect such as Kiryu Jilves, Gaia's Roar, but the substitution effect itself isn't a trigger ability. The substitution effect is an ability that occurs during the resolving.
• The ability of "When you do A, do B instead" from Perfect Galaxy, Spirit of Immortality seems to be a trigger ability at first glance, but it is a continuous ability with a substitution effect with its duration omitted.
  • The ability of "When you do A, do B" such as from Aqua Hulcus is a trigger ability as it does the B action after you do A. However, if it does the B action instead of the A action, it is a situational effect where the A effect never occurs.
• The "you may" or "If you do, ____" is treated as a cost. In this case, even if the specified action can't be performed due to the result of a substitution effect, the effect still occurs. For example, even if you destroy Aqua Soldier by Dark Soul Creation and the Aqua Soldier isn't destroyed as a result, you still draw 3 cards.
  • However, in the case of triggered capability abilities, the specified event must still be attempted to be triggered. For example, Aqua Hulcus returns to your hand when it would be destroyed. There, as it wasn't destroyed, it wouldn't draw a card for the ability of Super Trash Train, Fuuma Devil.
• There is also a trigger ability that reads "When you do A, if you have B, do C" In this case, B is treated as part of the effect. Therefore, even if B isn't satisfued at the timing of the A text, C can still occur if the condition is satisfied by the time of resolution (Example: See Alexander the 3rd, Emperor of the Demonic Eye, Mana Arms abilities, Riku, the Oracle)
  • On the other hand, if its written as "When you do A, if there is B, do D", it is treated as a condition. Therefore, it can't be triggered if you don't satisfy the C text of the effect at the time of the A initial trigger. (See Oriotis, Control Wings)
• Trigger abilities such as "At the start of your turn" and "At the end of your turn" don't trigger if the creature is not in the battle zone at the specified time.
  • Example) If you evolve Storm Genji Double Cross, the Super Temporal on an awakened psychic creature at the start of your turn, you can't use the meteorburn ability as he was not in the battle zone when the turn began, so the Meteorburn Awaken doesn't trigger.
• The term is also refereed to as a "Triggered Ability" in the Magic: The Gathering trading card game.

• 603. Trigger Ability
  • 603.1. Trigger abilities have a trigger condition and effect.
  • 603.2. Triggered abilities will automatically trigger each time the trigger condition is met. The triggered effect will be on standby once and wait to resolve.
    • 603.2a When a step begins, all abilities that have “at the start of STEP" in their text will trigger in that step.
    • 603.2b An ability triggers only once each time its trigger event occurs. However, it can trigger repeatedly if one event contains multiple occurrences.

      Example: A creature has an ability whose trigger condition reads, "Whenever a creature is destroyed". If two or more creatures are destroyed at the same time, the ability will trigger for each creature destroyed.

    • 603.2c Some trigger events use the word "is". These trigger only at the time the named event happens, they don’t trigger if that state already exists or trigger again if it persists. An ability that triggers when a card "is tapped" or "is untapped" doesn’t trigger if the card is put into a zone in that state.

      Example: An ability that triggers when a creature "is tapped" triggers only when the status of a creature that’s already in the battle zone changes from untapped to tapped.

    • 603.2d An ability triggers only if its trigger event actually occurs. An event that’s prevented or replaced won’t trigger anything.

      Example: An ability that triggers when a creature is put into a graveyard won't trigger if a creature is put into another zone.

    • 603.2e Some trigger abilities require a declarations of usage. Trigger abilities that would trigger in a private zone, such as 'Ninja Strike', 'Revolution Change' and 'Gate of Moonless Night' are examples of abilities that require a declaration of usage. These abilities, even when used from a public zone such as a graveyard or mana zone, still require a declaration of usage.
  • 603.3. Any abilities that trigger become abilities on standby. Then the abilities are resolved starting with the abilities of the active player.
    • 603.3a Some triggered abilities are written to use an ability with a specific icon. These abilities will be put on standby when they are triggered.

      Example: When a creature that has 'Kizuna Plus' attacks and puts a card underneath into your graveyard, even if the creature with the icon is destroyed before the ability resolves, the card is put into your ability when the ability is triggered. The 2 icon abilities that were chosen when you put a card underneath into your graveyard are put on standby.

  • 603.4. If a trigger ability has conditions, if the condition is satisfied at the time of resolving the ability, the ability is resolved. It does not matter whether the condition was satisfied at the time of triggering.
  • 603.5. Trigger events that involve cards changing zones are called "zone-change triggers". hand Everything subject to movement between zones including tags, battle zones, manas zones, cemeteries, It is ability to induce change.
    • 603.5a Abilities that trigger when a card is put into the battle zone can be found on creatures, cross gear, weapons and fortresses. Each time an event puts one or more cards into the battle zone, all cards on the battlefield (including the newcomers) are checked for any "put into the battle zone" triggers that match the event.
    • 603.5b Continuous effects that modify characteristics of a card are applied the moment after the card is put in the battle zone (and not before then). The card is never in the battle zone with its unmodified characteristics. Trigger abilities are checked after applying all continuous effects.

      Example: If a player has a 'Courtney, Summer Breeze Faerie in the battle zone and they put a nature card into their mana zone, that card is considered to be of every civilization as it is put into the mana zone. If that player also has a creature with the ability "Space Charge: Darkness", that ability will trigger.

    • 603.5c There are abilities that trigger even after a card containing such ability is put into a graveyard. The game "looks back in time" to determine if those abilities trigger, using the existence of those abilities and the appearance of cards immediately prior to the event.

      Example: A creature with the ability "Whenever a creature is destroyed, draw a card." and two other creatures are destroyed at the same time. The creatures are put into the graveyard, but the ability will trigger three times.

    • 603.5d Some abilities cause cards to be put into a zone in a certain state. These abilities are static abilities, not trigger abilities.

      Example: When a creature with a Shield Force ability is put into the battle zone, that creature has the Shield Force abilities immediately if a shield was chosen.

  • 603.6. An effect may create a delayed triggered ability that can do something at a later time.
    • 603.6a Delayed triggered abilities are created during the resolution of abilities, or as the result of a replacement effect being applied. A delayed triggered ability won’t trigger until it has actually been created, even if its trigger event occurred just beforehand.

      Example: If you have a creature that has the "Each turn, you may untap this creature the first time it's tapped. " effect, and you cast a spell that taps creatures, it will attempt to tap them. but won't occur if the creature had already been untapped earlier in that turn.

  • 603.7. There are abilities that trigger just before a shield would break with a trigger condition of "Before the break". These abilities trigger at the time when you choose shield to break, and they resolve before you break it.
    • 603.7a After resolving the standby effects of an ability that trigger 'before the break', if there are any other standby effects, resolve them before breaking the chosen shield.
    • 603.7b When resolving a standby effect with an ability that triggers 'before the break', you may cause a new shield to break, causing a new 'before the break' to trigger. In this case, the effect of the last triggered 'before the break' ability resolves before any new standby effects resolve or the originally chosen shield breaks. Then, if there are any other standby effects, they are resolved, the newly chosen shield is broken, and then the process returns to the process of breaking the originally chosen shield.

      Example: When attacking with 'Kakumeijin, Geima King Dragon' and breaking your opponents shield, the 'before the break' was triggered twice. For the first trigger, I cast 'Texas Storm' and put 'Kakumeijin, Geima King Dragon' on the top of the deck, and put it again, to break another of my opponent's shields. At this time, a third 'before the break' ability was triggered. In this case, you first resolve the third 'before the break' ability, and cast a spell, than break the chosen opponent's shield with 'Texas Storm'. Then resolve the second 'before the break' ability of the 2 shields that occurred by the first break, and then break the 2 shields that you had chosen with the attack of 'Kakumeijin, Geima King Dragon'.

From the Duel Masters - General Game Rules: Version 1.41 (April 12, 2024)

• 603. 誘発型能力の扱い
  • 603.1. 誘発型能力は誘発条件と効果を持ちます。
  • 603.2. 誘発型能力は、誘発条件を満たすたび自動的に誘発します。誘発した効果は一度待機状態となり、解決を待ちます。
    • 603.2a ステップの開始時に、「はじめに」誘発する能力がすべて誘発します。
    • 603.2b 誘発型能力は、その誘発条件を満たすたびに一度だけ誘発します。しかし、そのイベントが複数の出来事を含んでいる場合、複数回誘発することもあり得ます。
      例： 「いずれかのクリーチャーが破壊されるたび」という誘発条件の能力を持つクリーチャーがいるときに、複数のクリーチャーが同時に破壊された場合、その能力は破壊されたクリーチャーと同じ数だけ誘発します。
    • 603.2c 「になる」という語を用いている誘発イベントは、その示されたイベントが発生したときにのみ誘発します。元々その状態であった場合に誘発することはなく、その状態であり続ける間は再び誘発することはありません。同様に、カードがその状態でそのゾーンに入った場合にも誘発しません。
      例： クリーチャーが「タップ状態になった」ときに誘発する能力は、バトルゾーンにあるクリーチャーがアンタップ状態からタップ状態になった時にのみ誘発します。
    • 603.2d 能力は、その誘発イベントが実際に発生したときにのみ誘発します。置換されて行われなかったイベントによって誘発することはありません。
      例： クリーチャーが墓地に置かれることによって誘発する能力は、クリーチャーを墓地に置く代わりに他のゾーンに置いた場合には誘発しません。
    • 603.2e 誘発型能力の中には使用宣言が必要なものがあります。「ニンジャ・ストライク」や「革命チェンジ」、「無月の門」など、非公開ゾーンで誘発する誘発型能力は、すべて使用宣言が必要な誘発型能力です。これらの能力は、墓地やマナゾーンなど、公開ゾーンから使用する場合にも、使用宣言を行う必要があります。
    • 603.2f 誘発型能力の使用宣言は、カードの使用宣言とは異なります。誘発型能力の使用宣言とは、その誘発型能力を持つカードの持ち主であるプレイヤーだけがその能力の誘発を確認できる状況において（手札にある場合など）、そのプレイヤーがそのカードを見せて宣言することです。宣言されてはじめてその誘発型能力が誘発します。これは603.2の例外です。
  • 603.3. 能力が誘発したら、効果は一度待機状態になり、その時点で待機している全ての効果のうちターン・プレイヤーのものから順番に処理をします。
    • 603.3a 誘発型能力の中には、それに続くアイコンの能力を使うと書かれているものがあります。それらの能力は誘発した段階でアイコンに記された内容を含めて待機状態になります。
      例: キズナプラスを持つクリーチャーが攻撃して下にあるカードを墓地に置いた時、その後能力の解決前にアイコンを持つクリーチャーが破壊されたとしても、能力起動時に墓地にカードを置いた段階で選ばれたふたつのアイコン能力は待機状態になっています。
  • 603.4. 誘発型能力が条件を持つ場合、その能力の解決の時点で条件を満たしていれば、効果が解決されます。誘発した時点で条件を満たしているかどうかは問いません。
  • 603.5. カードがゾーンを移動することを含む誘発条件は「ゾーン変更誘発」と呼ばれます。手札・バトルゾーン・マナゾーン・墓地・山札などゾーン間での移動を条件とするものは全てゾーン変更誘発能力です。
    • 603.5a バトルゾーンに出た時の能力は、クリーチャーやクロスギア、ウエポンやフォートレスがバトルゾーンに出た時に誘発します。1つ以上のカードをバトルゾーンに出すたびに、今出たカードが持つ誘発型能力を含み、すべてのバトルゾーンに出た時に誘発する能力をチェックします。
    • 603.5b カードの特性を追加・変更する継続的効果は、カードがあるゾーンに置かれた瞬間にすぐ適用され、本来の特性のままでそのゾーンに置かれたことにはなりません。特性を条件に持つ誘発型能力は、その継続的効果適用後の特性をチェックします。
      例： 《薫風妖精コートニー》がいるときに、自然のカードをマナチャージすると、そのカードは全ての文明を持つカードとしてマナゾーンに置かれたことになります。この時、スペースチャージ（闇）の能力を持つクリーチャーがいれば、その能力は誘発されます。
    • 603.5c 誘発型能力の中には、その能力を持つカード自身がバトルゾーンを離れたり、山札や手札に移動したときにも誘発するものがあります。それらの能力が誘発するかどうかを判断するために、ゲームは「過去の状態を見る」必要があります。これらは、そのイベントの直後ではなく直前のカードの存在や状態に基づいて誘発します。この際、過去の状態を見ることができるのは、その能力を持つカード自身についてのみです。
      例： 2体のクリーチャーと、「クリーチャーが破壊された時、カードを引く」という能力を持ったクリーチャーがバトルゾーンにあるとき、すべてのクリーチャーを破壊する呪文を唱えた場合、その能力の誘発はそのクリーチャー自身の1回のみです。
  • 603.6. 効果によって、後で何かを行なう遅延誘発型能力が作成されることがあります。
    • 603.6a 遅延誘発型能力はカードの使用や他の能力によって、または置換効果の適用の結果として生成されます。実際に生成される前に、その誘発イベントが起こっていたとしても、過去にさかのぼって効果を発揮することはありません。
      例： 「このターンクリーチャーがはじめてタップするたびアンタップする。」という能力を持つ呪文を唱えたとき、実際に呪文を唱えた後で「このターンはじめてタップしたクリーチャー」に対してのみ誘発するのであり、呪文を唱える前にすでにタップしていたクリーチャーには誘発しません。
  • 603.7. 「ブレイクの前に」といった誘発条件を持つ、シールドをブレイクする直前に誘発する能力があります。これらの能力は、ブレイクするシールドを選んだ際に誘発し、そのシールドをブレイクするより前に効果を解決します。
    • 603.7a ブレイクする直前に誘発する能力により待機した効果を解決した後、他に待機している効果があれば、それらの効果をすべて解決した後で、選んだシールドをブレイクします。
    • 603.7b ブレイクする直前に誘発する能力により待機した効果を解決する際、それにより新たにブレイクするシールドが選ばれ、新たに「ブレイクの前に」能力が誘発することがあります。この場合、待機中の他の効果の解決や、最初に選んでいたシールドのブレイクより前に、最後に誘発した「ブレイクの前に」能力の効果を解決します。その後、他に待機している効果があれば、その解決を行ってから新たに選んだシールドをブレイクし、その後、最初に選んでいたシールドをブレイクする際の処理に戻ります。
      例：《芸魔王将 カクメイジン》で攻撃し、相手のシールドをブレイクする際、「ブレイクの前に」能力が2回誘発した。1回目で《テキサス・ストーム》を唱え、《芸魔王将 カクメイジン》を山札の上に置いて再び出し、相手のシールドを新たに1つブレイクしようとした。この際3回目の「ブレイクの前に」能力が誘発した。上記の場合、まず3回目の「ブレイクの前に」能力を解決して呪文を唱えた後、《テキサス・ストーム》で選んだ相手のシールドをブレイクします。その後、最初のブレイクで誘発した2回のうち、2回目の「ブレイクの前に」能力を解決し、それが終わったら《芸魔王将 カクメイジン》の攻撃で選んだシールド2つをブレイクします。
