Hope-Ender Coatl

The counterspell-on-a-body has a fixed shape, and this one sharpens it at the seam where those designs have always been weakest. Flash is the load-bearing keyword: like Mystic Snake, Frilled Mystic, and Draining Whelk before it, the creature exists to be held up and flashed in on the opponent's turn, so the body was never the tempo tax those cards get accused of. What changes here is where the counter lives. Those earlier creatures hang the interaction on an enters-the-battlefield trigger, which means the creature spell has to resolve first: counter the creature on the stack and the tax never happens. Anchoring the effect on the cast trigger instead fires it the moment the spell is put on the stack, independent of whether the creature ever resolves. If your opponent responds by countering the Coatl itself, the soft counter has already been put on the stack as a separate object; they still face paying (or not paying) the . And it is a tax, not a wall: pay and the spell goes through, the price for stapling countermagic to a permanent that outlives the exchange, with a flash flyer left over even on the "fail." Devoid does the quieter structural work. The card still demands blue mana to cast, but once it is on the battlefield it registers as colorless, dodging the color hosers and off-color removal built to punish a blue permanent.
