Benthic Infiltrator

Ingest only matters if the damage lands, and a 1/4 has no business connecting in combat on its own. The fix is baked into the same card: this creature can't be blocked, so the body that carries the mechanic is also the body that guarantees it triggers. That pairing is the whole reason this drone exists. Every turn it connects, it strips the top card off an opponent's library into exile, where the processor cards of its tribe could feed on it for value. The four toughness does its work on defense rather than offense: it walls early attackers it has no interest in trading with, and survives most of the damage-based removal aimed at a creature this small, which keeps the engine running turn after turn. Devoid keeps it colorless without making it read as artifact, the cosmetic touch that lets the Eldrazi look genuinely alien rather than merely blue. As a piece of evasive attrition it is slow, but it is a tidy self-contained rendering of the ingest-and-process loop: a guaranteed exile every combat, feeding a fuel supply rather than acting as a clock. What the combat damage does to a life total barely registers; the payload is the card it eats, banked in exile where the graveyard can never reclaim it.
