Confuse about Mismagius (Stormfront 7)

[Darksoldier2004]

I'm a little confuse about Mismagius Lv 33 ATK: Crash Chant Choose up to 4 in any combination of Pokémon Tool cards and Technical Machine cards in play (both yours and your opponent's) and discard them. This attack does 20 damage times the number of cards discarded in this way. how takes the damage from this attack ?

This attack does damage to the Defending Pokemon. That means your opponent's active pokemon in a regular battle.
