The Nuka-Cola Challenge — Whenever one or more creatures you control deal combat damage to a player, put a quest counter on Sierra and create a Food token.
Whenever you sacrifice a Food, target creature you control gets +X/+X until end of turn, where X is the number of quest counters on Sierra.
Sierra is a mono-white aggro-aristocrats engine: connect with creatures to stack quest counters and bank Food tokens, then sacrifice that Food to give a creature a massive +X/+X swing equal to your quest counter total. Early turns build a wide or evasive board to start the counter snowball; mid-game you turn Food into game-ending combat math or repeatable sacrifice value. The longer combat keeps hitting, the bigger every pump becomes.
Self-sustaining engine: combat damage produces both counters and Food, so the payoff fuels itself.
Pumps scale infinitely with quest counters, eventually turning any creature into a one-shot threat.
Food tokens fold into a broader sacrifice/lifegain subtheme for extra value.
Cheap, on-color commander that rewards going wide with evasive creatures.
Counters and Food are wiped if Sierra dies or gets bounced, resetting your scaling.
Mono-white means limited card draw and ramp to refill after a board wipe.
Needs to deal combat damage to function, so it stalls against heavy fog/blocker walls.
Pump is sorcery-speed-ish in practice and telegraphed, easy to answer with instant removal in response.
