prominent of these "battlecruisers" are the Eldrazi, all of whom are colorless because they (in game-universe terms) have transcended the colors of mana. The smallest Eldrazi creature is , a common 7/7 for 9 mana; the largest is , a mythic rare 15/15 for 15 mana. To help get these enormous creatures into play quickly, the set features many alternate sources of mana (particularly the "Eldrazi spawn," which can be sacrificed for colorless mana) and a dearth of cheap creature removal.

After the rebound has triggered, the spell enters the graveyard as normal. Totem Armor is found on white, green and blue Aura Enchantments.
