Once during your turn (before your attack), you may switch 1 of your opponent's Benched Stage 2 Evolved Pokémon with 1 of the Defending Pokémon. Your opponent chooses the Defending Pokémon to switch. This power can't be used if Victreebel is affected by a Special Condition.
The Defending Pokémon is now Asleep and Poisoned.
Flip a coin. If heads, this attack does 40 damage plus 30 more damage.
