Drifblim

It can generate and release gas within its body. That’s how it can control the altitude of its drift.

Balloon Tackle (60): Drifblim does 20 damage to itself.

Take Away: Shuffle Drifblim and all cards attached to it back into your deck. Then, your opponent shuffles the Defending Pokémon and all cards attached to it into his or her deck. (You choose your new Active Pokémon first.)
