Havengul Vampire

Two growth clauses stapled to one fragile 2/2, each rewarding the board state the other thrives in. The combat trigger pays off the attack that connects; the death trigger pays off the trades, sacrifices, and chump blocks piling up around it. In a deck of cheap expendable bodies, the second ability becomes a snowball: every creature that dies anywhere, yours or theirs, makes this bigger, so a grindy stall where creatures keep dying climbs it out of removal range a counter at a time. The catch is the timing of that growth. The death trigger only matters while it is still on the battlefield, so a board wipe that destroys it alongside everything else does it no favors: it goes to the graveyard with the rest, and the triggers for the other deaths resolve too late to save it. At four mana, it arrives in the mid-game, when the table already has a creature or two willing to die, but it still has to dodge a removal spell before either counter source compounds. Land one swing or one death on the stack and the math tips fast; leave it alone across a long game and it inflates on its own. It pulls in two directions at once, which is the point: aggressive enough to want to attack, attrition-friendly enough to reward the games where attacking is hard. Plenty of counter-accumulating creatures from the same era picked a single trigger; pairing a combat-damage clause with a global death clause makes it equally comfortable in the deck that races and the deck that grinds.
