A-Master of Winds
A defensive flier that replaces itself on entry is fine but forgettable spellslinger fodder, so the real design lives in the toggle: every instant, sorcery, or Wizard spell you cast lets you flip the base stats to 5/1 or back to 1/5 for the turn. The reversibility is the point. Because the choice is yours on each casting, you can swing as a 5/1 during your own turn and settle back into a 1/5 to hold the ground on the way back around. That rewards the specific rhythm of a busy hand (multiple castings in a turn, instant-speed reach) rather than raw creature count, converting what reads as a pure value engine into a clock whose speed scales with how much you are actually doing. The Arena-only rebalance that this "A-" version represents runs opposite to the usual assumption: instead of trimming power, it added a point of toughness to a body that was too soft to matter as printed. That extra durability is precisely what protects the engine, since a 1/5 can now block through the turns you spend setting up the swing, while the 5/1 side stays a one-turn commitment you opt into only when you have the tempo to spare. The bump exists because the printed version was quiet enough on Arena to earn one; the change is a durability fix, not a nerf.
