Necrosquito

A 0/0 body that only exists because oil counters are propping it up: it lands as a 2/2 flier, then grows every time another creature or artifact you control hits the graveyard from the battlefield. The design ties the oil-counter mechanic, which usually spends its charges on kicker-style abilities and level-ups, to a self-feeding graveyard trigger, so the card behaves less like a flying beater and more like a ledger of your own attrition. Every creature that trades in combat, every artifact you crack for value, every token fed to a sacrifice outlet nudges the counter total up, and because it counts artifacts as well as creatures, the trigger fires in decks that would never otherwise field a growing threat. The evasion is what makes the accumulation matter: a ground creature that gets bigger the longer a grind goes on is easy to chump, but a flier that quietly climbs out of removal range while your board erodes is a real clock. The catch is fragility at both ends. It starts with just two counters, so any effect that removes counters or bounces it resets the whole project, and a 0/0 base means it never recovers on its own. It rewards the kind of deck that treats its own permanents as fuel rather than assets, turning the cost of that plan into a wincon that scales with how hard you are willing to grind.
