Ezuri's Archers

A one-drop reach blocker that punishes the thing it was built to stop. Reach lets a ground-bound elf trade up against fliers, but the conditional pump turns the trade into a beating: block a flier and the body swells to a 4/2 for that combat, large enough to kill almost any early evasive threat outright while surviving most of them. The design discipline is that the bonus is triggered, not static, and tied specifically to blocking flying: this archer is a 1/2 doing nothing on an empty board or against ground creatures, and only earns its keep when an opponent commits to the air. That makes it a punish-the-plan card rather than a generic body, the green answer to a flyers-heavy strategy that rewards the defender for guessing right about what the attacker is doing. It is a narrow, reactive piece of design, the kind of green common that exists to give the color a clean, cheap answer to evasion without handing it removal: you cannot point this at anything, you can only wait for the flier to swing into it. Against an opponent with no air game it is a speed bump; against one leaning on small fliers it is a wall that bites back.
