Pokémon PowerPoison Mist
Once during your turn (before your attack), you may flip a coin. If heads, until the beginning of your next turn, all Poisoned Pokémon take 20 damage instead of 10 damage from Poison between each player's turns. This Power can't be used and stops working while Weezing is Asleep, Confused, or Paralyzed.
Gas Explosion40
Weezing does 30 damage to itself. If this attack Knocks Out the Defending Pokémon, your opponent's new Active Pokémon becomes Poisoned.
