Kederekt Parasite

The two-color tax made literal. This punishes opponents for the most fundamental thing they do in a game of Magic: drawing cards. But the trigger only fires while you control a red permanent, which is the whole tension of the design. A one-mana black body that does nothing on its own, gated behind a color it cannot produce, is a deliberate signpost pointing players toward Black-Red as a deckbuilding identity rather than a piece of removal or a clock. The damage is incidental (one point per draw, dealt by an optional triggered ability that pings on each opponent's draw), and against a deck that draws naturally it accrues quietly, but the real payload arrives when paired with a draw-forcing effect: hand each opponent extra cards and the Parasite turns generosity into a noose. That combination is the only context where it stops being a curiosity and becomes a finisher, and it explains why the card reads as a build-around rather than a staple. The Horror is a creature in name and a recurring damage trigger in practice, the kind of color-pair payoff that asks you to commit to two colors before it does anything, and rewards you precisely as much as your deck weaponizes its opponents' card flow.
