Edge of Eternities is a laudably weird set, and its colorless cards embrace that ethos: there's a new Eldrazi that has a pseudo-Solemn Simulacrum effect, there's a 9/9 that you can cast for three, there's a card that casts Hive Stirrings every turn, and there's a Mindslaver variant with an Emrakul-sized activation cost
