Aeromunculus

Adapt was Simic's answer to an old tension: mana sinks that dump counters onto a body are strongest when the body already has counters, which snowballs games that are already won and does nothing when you are behind. Adapt's conditional clause fixes that by refusing to stack. Once this Homunculus has a +1/+1 counter, the ability does nothing, so the growth caps at a single tick unless something else strips the counter off first. That single conditional turns a repeatable pump into a one-and-done investment, which is the whole reason the ability can carry an evasive body without warping the curve. What you actually get is a flier that starts as a 2/3 and grows to a 3/4 on its own clock, holding open the flying lane while a proliferate effect or a counter-doubler turns the one-time adapt into something larger than the printed ceiling suggests. That interaction is where the design becomes interesting: adapt gates the base card at one counter, but nothing stops external effects from piling more on top, so the ability reads as a floor rather than a limit. On its own it is a patient two-color flier with a mana sink attached; slotted into a shell built to multiply counters, the sink becomes the seed.
