Alolan Sandslash-GX

If this Pokémon is your Active Pokémon and is damaged by an opponent’s attack (even if this Pokémon is Knocked Out), put 3 damage counters on the Attacking Pokémon.

This attack does 100 damage to each of your opponent’s Pokémon that has any damage counters on it. (You can’t use more than 1 GX attack in a game.)
