Staraptor

Flip a coin. If heads, put 1 of your opponent's Benched Pokémon and all cards attached to it on top of your opponent's deck. Your opponent shuffles his or her deck afterward.

The Defending Pokémon can't retreat during your opponent's next turn.

As long as Staraptor is your Active Pokémon, any damage done by attacks from your opponent's Stage 2 Evolved Pokémon is reduced by 20 (after applying Weakness and Resistance).
