Dreadwing

A black one-drop whose entire payoff lives in two off-color pips: a Grixis-shard design that asks a mono-black creature to find blue and red mana before it does anything beyond chump-blocking. The body is unremarkable, and that is the point. The activated ability is the whole reason to run it, a repeatable evasion-and-pump button that lifts a 1/1 Zombie into a four-power flier for as long as the mana keeps flowing. This is shard identity expressed at the rate level, rewarding a manabase that already reaches into all three colors and punishing anyone who splashes the body without committing to the cost. Each activation touches only this creature and only until end of turn, so it reads less like a finisher and more like a mana sink: a way to convert a flooded Grixis board into incremental flying damage one turn at a time. The tension sits in the activation rather than the casting, an unusual place to load a creature's cost. You pay a single black to put it down, then pay a blue and a red (plus one generic) every time you want it to matter, and the gap between cheap entry and recurring upkeep on the ability is the design's signature.
