What is Pokemon TCG?
The Pokemon Trading Card Game is a two-player game where each player builds a 60-card deck around a team of Pokemon and battles to knock out the opponent's Pokemon. Every time you knock one out you take a Prize card - take all of your Prizes (usually six) to win.
How a game plays
Each turn you draw a card, then play Basic Pokemon, attach Energy, use Trainer cards and attack. Attacks need the right Energy attached; when a Pokemon's HP runs out it is knocked out and the attacker takes a Prize. Basic Pokemon evolve into stronger Stage 1 and Stage 2 forms as the game develops, so a deck is about building an engine of Pokemon, Energy and Trainers that work together.
