Dragalge (FLI #53)

Ability • Poison Point

If this Pokémon is your Active Pokémon and is damaged by an opponent's attack (even if this Pokémon is Knocked Out), the Attacking Pokémon is now Poisoned.

Flip 2 coins. For each heads, discard an Energy from your opponent's Active Pokémon. If both of them are tails, this attack does nothing.
