Shuffle your deck and draw 7 cards. The turn goes like this. Do any of these in any order any number if times. Only one energy card can be placed during your turn. It tells you how much you need beside the attack and how much damage it does.
Some abilities require sacrificing energy.
If it is attacked by the type it is weak against, the damage is doubled. It is turned sideways to indicate it is paralyzed. However, when you declare an attack, you must flip a coin.
