Sierra, Nuka's Biggest Fan
A ratchet that only turns one direction. The engine begins in combat: whenever your creatures connect with a player, Sierra banks a quest counter and mints a Food token, so every profitable attack quietly raises a number that never falls. The second ability sits apart from combat entirely. It waits for you to sacrifice a Food (through any outlet, anytime), then reads the current count and pumps a creature by that much. Nothing spends the counters; the sacrifice simply consults them, so the size of the pump tracks how long the board has been swinging rather than any single turn's investment. That separation is the whole design. Early Food trickles in and the +X/+X is negligible, but a few connected attacks turn one cracked Food into a lethal combat trick, and because the trigger fires on any Food and not only Sierra's own, unrelated Food sources plug straight into the escalating count. The archetype work is real: go-wide aggression and Food rarely share a payoff, since one wants to keep attacking while the other drifts toward attrition and lifegain. This wires the two together, using the same combat that fuels an aggressive board to arm a lifegain subtheme with teeth. The 3/4 body is built to survive the attacks that feed the loop and can be the target of its own pump, so the card that manufactures the counters can also cash them in for the swing that ends the game.
