Processor Assault
Five damage to a creature for two mana is a rate that shouldn't be printable, and the additional cost explains why it is: this spell won't cast unless you can feed it something already sitting in exile under an opponent's ownership, which you then dump into their graveyard as you cast. So it isn't removal you can lean on; it's the back half of a two-card engine, compressed into a cost line rather than spread across the battlefield. The processing mechanic was an experiment in feedback loops paired with ingest: ingest banished an opponent's card to exile, and cards like this one cashed that stranded card in for a payoff, here a burn spell that overkills nearly anything it targets. The dependency is total. With nothing exiled to spend, the spell is uncastable, a stricter tax than the "discard a card" or "sacrifice a creature" riders that merely nudge you toward a cost; those let you cast on turn one if you're willing to pay, while this one gates on a board state you have to manufacture first. Devoid strips the spell's color to nothing (it stays red by identity, since remains in the cost), so it reads as colorless on the stack in line with the Eldrazi-aligned effects it belongs to. The bet every processor made lives here: keep the exile fed and the rate is a steal; leave a piece out and you're holding an uncastable card.
