Infinite Attacker

Infinite Attacker is a term given to a creature that has the ability to untap when it attacks.

"Fists of Forever" type
This type of infinite attacker untaps if you win the battle.

Although it can be a powerful ability, you can't make use of it if you can't battle your opponent's creatures.
 * This makes it compatible with cards that tap creatures such as Super Spark or creatures that Can Attack Untapped Creatures.

It is also important to be on a high power creature or to have an ability to Win All Battles.
