Guardian Shield-Bearer

Megamorph almost always points its bonus counter inward, growing the flipped creature and stopping there. This one aims the counter at a second target, so turning it up mid-combat plays out as a double growth: the revealed creature gets its megamorph counter, and another creature you control gets one too, both landing at instant speed during whichever attack step you choose to spring it. That sideways reach is the whole distinction of the design; the rest of green's megamorph creatures keep their reward to themselves. The price tag keeps the effect honest. Three to bank it under cover, four more to flip, so the complete arc runs seven mana laid out across turns, and what you get for it is two counters rather than a game-ending swing. That deliberate spread makes it a patient value play instead of a tempo one: you set the hidden creature down early, then wait for the combat step where the extra counter either pushes lethal or rescues a trade that would otherwise go the wrong way. As curve-filling green fair-creature material, it earns its keep by being a body first and a combat trick second, most at home in a counters-matters or go-wide shell where placing a spare +1/+1 at exactly the right moment stretches a little further than the mana outlay suggests.
