Commander 2015 features five enemy colored 100-card decks (342 different cards). There are 56 new cards legal in Vintage and Legacy. Each of the five preconstructed decks comes with one oversized foil commander card, 10 double-faced tokens, a deck storage box, a strategy insert, a rules reference card and 15 new cards.
Each preconstructed deck was designed with a primary theme and a secondary theme. The main new commander in the deck matches the primary theme, while the alternate new commander matches the secondary theme. For instance, the white/black deck, Call the Spirits, has a primary enchantments theme supported by Daxos the Returned and a secondary lifegain theme supported by Karlov of the Ghost Council.
