The Trainer Challenge is also a great opportunity for players to get acquainted with the new Black and White rules before they come into effect (whenever that is). The two most important changes are:
- You can play Trainers, Supporters, and Stadiums on your first turn, even if you go first.
- You cannot play Rare Candy on the first turn of a game or on the first turn a particular Pokemon is in play.
The Pokemon Trainer Challenge can be found at pokemontcg.com. It's a great place for newcomers to learn the ropes and experienced players to hone their skills.
