Lurching Rotbeast

The 4/2 body is the tell: this is a creature priced to be cast when nothing better is happening and pitched the rest of the time. The black cycling cost is what keeps it relevant, converting a marginal beater into a one-mana cantrip the moment your hand doesn't want a fragile attacker. That flexibility is the entire point of the design slot it fills: a common-rarity creature that almost never feels dead, because the floor is paying one black to replace it and the ceiling is four power swinging into an opponent who has to answer it. Cycling has carried this filler-with-an-exit role since it first appeared, and the four-power-two-toughness frame is a deliberate calibration: big enough to trade up or pressure a planeswalker, frail enough that you won't mourn discarding it. It leans on nothing more than a black source in your mana and pays out in consistency rather than raw power, smoothing draws in the games where the beast is irrelevant and adding a body in the games where it isn't.
