Trawler Drake

An 0/0 that enters as a 1/1 flyer, then grows every time you cast a spell that isn't a creature: the design bolts a graveyard-free, exile-free counter engine onto the body of an evasive threat. The trick is where the growth comes from. Most "grows when you cast" creatures ask for a keyword or a specific card type, but the oil-counter trigger here fires on any noncreature spell, which quietly turns your removal, your card draw, your cheap interaction into free stat increments on a permanent that is already dodging the ground. Nothing about the trigger is optional or conditional; it does not require the spell to resolve, only to be cast, so a countered spell still feeds it. That makes the Drake a natural top-end for a deck that was going to play its own game plan anyway: it never demands you contort the deck toward artifacts or a specific archetype, it just taxes every noncreature card you were already casting into a small permanent reward. The counter accrual is one-directional, so the body only climbs, and because the counters are printed as oil the card slots cleanly into any shell built to double, proliferate, or otherwise care about that resource. The weakness is baked into the same math: with no spells cast and no removal for the summoning-sick 1/1 body, it is a slow starter that wants a full turn cycle before it earns its keep.
