If you're already familiar with the Magic: The Gathering trading card game, but not with the Betrayers of Kamigawa expansion, now you have the chance to learn more about it! This set focuses on ninja, hence its Japanese name.
Spiritcraft is one of the preconstructed theme decks with cards that use white and green as their color, though all 165 cards in the set have a black border. The rare cards in this deck are Kodama of the Center Tree and Oyobi, Who Split the Heavens, belonging to the Creatures type of cards.
Given that you get the basic 60 cards that you need for any challenge as well as a strategy insert, you can consider yourself ready to battle, even if you don't get the rules of the game.
