Plaxmanta

Built to punish the splash, this blue beast asks for a green mana on the way in, then politely leaves if you didn't pay it. The structure is the point: flash plus a shroud-granting enter trigger turns it into a reactive protection spell, flashed in during your opponent's turn to hand your whole team untargetability until end of turn. That window answers spot removal and targeted burn, but it does nothing against a sweeper, which never targets anything, and nothing against edicts, which name the player rather than any creature; the protection is a wall against pointed effects aimed at your board, not a blanket of immunity. The self-sacrifice clause is the real toll. Cast it on blue mana alone and you get the shroud once, then watch it sacrifice itself before the turn is out; spend the green and the 2/2 simply stays on the battlefield, a lasting body rather than a one-shot trick. It's mana-base extortion dressed as a creature, refusing to be a clean blue inclusion, which is how the design keeps a flash-in-and-protect tool from slotting into any tempo shell for free. The choice of shroud over hexproof cuts both ways: it shields against your opponent's targeting but also walls off your own auras and pump spells for the turn, so the protection is all-or-nothing rather than something you sequence around. A defensive card that demands you've already committed to both its colors before it leaves anything behind.
