Momo, Friendly Flier

Discount and payoff bundled into the same white one-drop, with enough friction built in to keep either half from running away. The cost reduction is deliberately rationed: only the first non-Lemur flying creature spell each turn, only one mana off, and only on your own turns, so it accelerates a curve rather than fueling a storm-style chain. That rationing is what lets a one-mana body touch every subsequent flier without snowballing on its own. The pump follows the same logic, keying off other fliers entering rather than off this creature, so the payoff is entirely a function of how wide the board goes, and every buff expires at end of turn. The result is a lord that stays a 1/1 until arrivals do the work, then swings briefly large during a flurry of them. It sits in the lineage of cheap tribal glue that asks the deck around it to justify the discount, the way early anthem-and-enabler one-drops did, but the one-per-turn clause and the temporary buff mark it as a later design sensibility: aggressive on rate, conservative on ceiling, built to reward a dedicated flying board without ever being the whole plan.
