Blacksnag Buzzard

Two mechanics that both trade in timing land on the same 2/1 body, and each covers for the other's blind spot. Plot lets you sink mana on a quiet turn to bank the card, exiling it from hand so a later turn can cast it as a sorcery without paying its cost, smoothing a turn where you have leftover mana and nothing to spend it on. The death-conditional counter is the patient half: a one-time check that reads the board as the creature enters and asks a single question, has anything died this turn yet. That is not the drip of a triggered ability that fattens up over a game; it is a snapshot taken at the moment of arrival, and either the corpse is already there or the bonus is gone. Plot is the tool that lets you choose which turn to take that snapshot on. Cast the plotted card after combat or a sacrifice outlet has already killed something, and it arrives as a 3/2 evasive threat with no mana owed, costing nothing against that turn's tempo even though the card was committed earlier. That sequencing is what the design is built around: the counter is not a passive rider you carry from the moment you draw it, it is a payoff tied to a single window, and plot is what lets you line the enter-the-battlefield check up with a turn that has already produced a body. The casting mode that flattens your curve is also the one that most reliably switches the bonus on.
