DM-01 Base Set
While the ability was originally featured only on spells, it was later introduced on creatures in DM-04. It enables a spell to be cast or a creature to be summoned for no cost if they are returned to your hand while previously a shield in your shield zone. This enables a game to easily be reversed with a card, such as a DNA Spark disabling any more of your opponent's creatures from attacking and also disabling the opponent's creatures from the battle zone from blocking your next attack, or a Terror Pit removing your opponent's major threat, such as a fatty creature. Triggering Shield Triggers is one of the reversal and risk factors in Duel Masters, as it enables the opponent to act in a turn where he usually cannot do anything at all.
Cards with the shield trigger ability tend to be more expensive in mana cost than their regular counterparts (Such as a creature having a power to cost ratio of 5 to 1000 or a spell costing 6 or 7). Due to this factor, Quasi-Vanilla creatures with Shield Trigger are often considered among one of the worst creatures in the entire game due to them having a heavily imbalanced cost to power ratio as well as bringing no direct advantage other than potentially being summoned for no cost.
As creatures with Shield Trigger are being summoned into the battle zone instead of being "put", if a creature with a ”When you summon this creature” effect is put into the battle zone via Shield Trigger, the effect will trigger.
- A creature such as Heavy Death Metal, End of the Century which can only be summoned can be put into the battle zone like normal this way. Vice Versa, if an ability prevents you from summoning a creature or casting a spell, you can't use the shield trigger abilities of those respective card types.
The below table illustrates the chance of seeing a card that has "Shield Trigger" as one of your 5 shields when they are broken, based on the number of cards with the ability in your deck.
