Whiptongue Frog

A blocker that pays a toll to become an evader. The 1/3 body is built to sit on defense, soaking up early attackers and surviving the small ground creatures it faces (it bounces off a 2/2 and eats a 2/1), but the repeatable flying activation means it never reads as purely passive: hold up a single blue mana and the same creature that was wall-shaped a moment ago can swing past a ground stall or rise to block a flier it had no business reaching. The design logic is the activation cost itself: not a tap, not a once-per-turn limit, but a raw mana payment that can be paid at any time the board calls for it. Flying does not stack, so there is no late-game mana sink here; the value is purely in the timing, in being able to convert a defensive body into an attacker (or an air blocker) on the exact turn you need it, without telegraphing the plan a turn early. The toughness-heavy stat line ensures the frog survives long enough for that flexibility to matter. It is a common-rarity utility creature, the kind printed to give a controlling blue deck a body that defends early and chips in late without demanding a deckbuilding commitment. Nothing about it asks to be built around; it asks only that you have a spare mana when the board state calls for a frog in the air.
