Poké-BodyTerritoriality

If your Active Pokémon is damaged by an opponent's attack (even if that Pokémon is Knocked Out), put 2 damage counters on the Attacking Pokémon. You can't put more than 2 damage counters in this way.

If your opponent has any Benched Pokémon, this attack's base damage is 30 instead of 60 and this attack does 30 damage to 1 of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)

Flip 2 coins. If both of them are tails, this attack does nothing.
