Weezing

Put damage counters on the Defending Pokémon until it is 10 HP away from being Knocked Out. Weezing does 70 damage to itself.

The Defending Pokémon is now Poisoned. If the Defending Pokémon tries to attack during your opponent's next turn, your opponent flips a coin. If tails, that attack does nothing.
