What is it?
Every player opens one booster, chooses which cards to play and adds Basic Energy cards as desired, to end with a 10-card deck. Then, play against every other player! There's just 1 prize card, the "Mutant" rule applies (Pokémon can evolve into Pokémon of the same type) and you won't lose due to drawing from an empty deck.
Your booster to build a deck, 10 points, just for playing!
3 wins: 20 points 2 wins: 10 points
