Each deck set includes 1 ready-to-play deck of 100 Magic cards (2 Traditional Foil Legendary cards, 98 nonfoil cards), a 2-card Collector Booster Sample Pack (contains 1 Traditional Foil or Nonfoil alt-border card of rarity Rare or higher and 1 Traditional Foil Borderless Common or Uncommon card), 1 foil-etched Display Commander (a thick cardstock copy of the commander card with foil etched into the cards border and art), 10 double-sided tokens, 1 deck box (can hold 100 sleeved cards), 1 Life Wheel, 1 strategy insert, and 1 reference card
These creatures can be cast for free with their evoke cost, just requiring you to exile a card that matches their color from your hand
