Toxapex GXGX

Flip 4 coins. This attack does 30 damage for each heads.

Your opponent’s Active Pokémon is now Poisoned. Put 10 damage counters instead of 1 on that Pokémon between turns.

Prevent all effects of attacks, including damage, done to this Pokémon during your opponent’s next turn. (You can’t use more than 1 GX attack in a game.)
