Dominator Drone
The reward structure here is what makes the printing legible: a body that drains two life from each opponent on entry, but only when the ingest package around it is already assembled. The condition is "another colorless creature," and in the Eldrazi drone shell that is a low bar, which is the point. This is the drain payoff for a decidedly aggressive read of the colorless-matters theme: rather than asking you to grind exile piles into a Blight Herder or a processor payoff, it simply cashes board presence into life loss the moment it lands. Ingest on the same card doubles the message, chipping the opponent's library as combat resolves without much caring whether you ever process what you banished. The devoid line is the connective tissue: it lets the drone count as a colorless creature for the next one and feed the wider "if you control a colorless creature" web these decks lean on. Where most of the exile-and-process suite treats the opponent's library as a resource to spend later, this one treats it as incidental and puts the clock front and center. It is the aggressive end of a mechanic that was mostly built to be slow and inevitable.
