When you play this Pokémon from your hand to evolve 1 of your Pokémon, you may flip a coin. If heads, choose 1 of your opponent's Pokémon. Your opponent shuffles that Pokémon and all cards attached to it into his or her deck.
Your opponent switches the Defending Pokémon with 1 of his or her Benched Pokémon.
Although it never saw competitive play during its lifespan in the Standard format, this card was temporarily banned from all official Pokémon events in the Expanded format on September 1st, 2015. This is due to Forest of Giant Plants making it possible to use its Ability, Giant Fan, multiple times in one turn, potentially clearing the opponent's field and defeating them before they could do anything in that match; this combination of cards created an undesirable playing environment, prompting the ban.
The ban was lifted on August 18th, 2017, due to Forest of Giant Plants being banned from the Expanded format on the same date.
