Armor monster

Armor Monsters are a series of monsters exclusive to the anime. Armor Monsters can be recognized by the fact that, where on a normal Effect Monster it would read "Effect", Armor Monsters have "Armor".

Only one "Armor Monster" can attack per turn. If there are 2 or more "Armor Monsters" on your side of the field, and one of them is declared as an attack target, you can change the target to any other "Armor Monster" on your side of the field.
