If you've never played the trading card game before, it's pretty simple. You put a Pokemon out onto the field, attach energy to that 'mon, and use its attack. Whenever you knock out an opponent's Pokemon, you get a prize. First player to collect all the prizes is the one that wins. You can also win if your opponent runs out of Pokemon to put into play, or if they run out of cards in their deck. It's a system that is incredibly easy to learn. That's not to say it doesn't have its nuances. This item cannot be returned or refunded, please visit Best Buy Return Policy to learn more.
