Each deck set includes 1 ready-to-play deck of 100 Magic cards (2 Traditional Foil Legendary cards, 98 nonfoil cards), a Collector Booster Sample Pack (contains 2 Traditional Foil or nonfoil special treatment cards, with 1 Extended-Art card of rarity Rare or higher and 1 alt-art, alt-frame card of rarity Uncommon or higher), 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
Alternatively, when paired with a large enough board state, an Altar of Dementia is capable of milling the remainder of an opponent's library, causing that player to lose the game the next time they'd draw a card
Thats where Collector booster boxes come in
