The Vision and Scarlet Witch

A ritual that grows. The trigger fires on every spell you cast, not just noncreature spells or your first spell of the turn, which turns this into a self-refunding mana engine: cast something, get red mana back and a permanent bump to the body. The two effects reinforce each other cleanly. The mana can be poured straight back into the next spell, and the +1/+1 counter accumulates whether or not you use the mana at all, so a busy turn leaves you with both a fuller board of resolved spells and a flier that has quietly climbed out of removal range. The design here is the storm-shell payoff repurposed as a beater: where most cast-count engines cash out in damage or tokens, this one banks the value into a single evasive threat and a persistent mana rebate. The catch that keeps it from spiraling is that both halves are strictly incremental. There is no doubling, no per-spell card draw, just one red and one counter each time, which means the ceiling scales with how many spells you can actually chain in a turn rather than exploding on its own. Evasion is what pays off all that accumulation: a creature that swells every cast is a curiosity until it can go over the top, and flying converts those stacked counters into a clock that actually connects.
