Meklord Army of Wisel (EXVC-EN012) [Extreme Victory]

This card gains 100 ATK for each face-up "Meklord" monster on the field, except this card. Once per turn, when another "Meklord" monster you control declares an attack on a Defense Position monster your opponent controls, you can activate this effect. During that battle, if the DEF of the selected target is lower than the ATK of the attacking monster, inflict the difference as Battle Damage to your opponent.
