Glaceon

Poke-BODY — Chilly Breath: As long as Glaceon is your Active Pokémon, your opponent's Pokémon can't use any Poké-Powers.

Avalanche (70): Flip a coin. If heads, this attack does 20 damage to each of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
