Each turn can begin by drawing a card, and then doing any appropriate actions, like: Attaching an Energy card to a Pokemon (only limited to once per turn) Evolving a Basic Pokemon to its Stage 1 form (can be done as many times per turn as possible) Triggering the effects of your Pokemon abilities (most abilities can only be played once per turn) Use Trainer cards (Supporter and Stadium cards can only be played once per turn, but other types of Trainer cards can be used multiple times in the same turn) Retreating and paying the retreat cost of your Active Pokemon (only limited to once per turn, and as long as you have at least one benched Pokemon to replace your Active Pokemon) Attacking the opponents Active Pokemon (only limited to once per turn, and doing this action automatically ends your turn) You can also end your turn without making any attacks by simply announcing it to your opponent

It's also one of the best cards for Type Four with infinite mana but just one spell per turn where the mana cost on this won't matter you can always cast it when needed
