Each player counts the number of cards in his or her opponent's hand. Each player shuffles his or her hand into his or her deck. Then, each player draws a number of cards up to the number of cards his or her opponent had. (You draw your cards first.)
Discard as many Energy cards as you like attached to your Pokémon. For each Energy card you discarded, flip a coin. This attack does 50 damage times the number of heads.
