Blocker (Whenever an opponent's creature attacks, you may tap this creature to stop the attack. Then the 2 creatures battle.)

■ Whenever this creature blocks, untap it after it battles.

Spiral Grass in DM-02 was the first creature with the ability to be released, with La Byle, Seeker of the Winds from DM-05 shortly after. After that, Ikaz, the Spydroid in DM-10 and Balhols, Demonic Elemental in DM-13 were introduced as lightweight and heavyweight replacements for the former cards. In addition, Reesa, Infinity Elemental, Choppurun, Love Love Guardian, Kuukai, Finder of Karma and Invincible Giant Mecha Spartan J also exist.

They are able to win battles easier when increased by +3000 power by Murmur, Vizier of Formation.
You may use a creature that has a "Fists of Forever" effect such as "Meermax, Mobile Vizier" as a pseudo Infinite Blocker, however such cards and "Reesa, Infinity Elemental" will only untap if they win a battle and will otherwise remain tapped even if they don't leave the battle zone due to another effect.
- When you have a Silver Glory, Invincible Fortress attached to one of your shields, your creatures will win all battles regardless of their power.
If you cross Grand Cross Catastrophe or Petrial Flame with these creatures, there will be limited ways through these creatures. A beatdown or rush deck may have no answers to deal with it.
Ikaz, the Spydroid actually allows you to "choose one of your creatures in the battle zone. Untap it after the battle.", so you can untap another creature.
This ability is seen on Adge, Emperor of the Gods when linked with 3 other Emperor of the Gods, but it must be given the blocker keyword from another effect.
In the case of a player controlling an 'Infinite Attacker' while the other play has an 'Infinite Blocker' that can't be destroyed, the attacker is the player who chooses whether the attack stops, changes to the opponents turn, and another game is played.
The untap is done after the battle. Therefore, its not untapped when the battle itself doesn't occur due to the effect of replacing a battle such as Utopia Ever, Zenith of "Destruction" or Rumble Lecter, Terror Awakened.
With Codefight Alibi Trick, you can untap a creature that has blocker (such as Perfect Madonna, Channeler of Suns). After the attack is declared by your opponent, this ability triggers allowing you to declare a block with the creature, making it an infinite blocker. It is important to know the timing of Active Player and Attack Trigger abilities. However, a card such as Prin Prin, the Victorious can prevent a block completely.
