Forerunner of Slaughter (BFZ)

Creature — Eldrazi Drone

Devoid (This card has no color.) {1}: Target colorless creature gains haste until end of turn.

Niche haste enabler for colorless strategies, but the narrow creature type requirement and modest rate make it a fringe pick even in dedicated Eldrazi decks where better alternatives exist.
