Mega Rayquaza ex

When you play this Pokemon from your hand onto your Bench during your turn, you may use this Ability. Look at the top 4 cards of your deck and attach a Basic Energy you find there to this Pokemon. Shuffle the remaining cards and put them on the bottom of your deck.

This attack does 50 damage times the number of [R] and [L] Energy attached to all of your Pokemon in play.

When your Mega Evolution Pokémon ex is Knocked Out, your opponent takes 3 Prize cards.
