Voltorb

Choose 1 of your opponent's Pokémon. Flip a coin. If heads, this attack does 20 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)

Search your discard pile for a Energy card and attach it to Voltorb.

Flip a coin. If heads, the Defending Pokémon is now Paralyzed.
