Kianne, Corrupted Memory

Parity as a toggle switch is the whole trick here, and it turns a body-growth engine into a flash-timing engine that rewrites which half of your deck can be held up on any given turn. A 2/2 that grows every time you draw would ordinarily just be a value clock; instead, each counter flips the permission. Start at an even power and your noncreature spells (removal, counters, card draw) all gain flash; nudge it to odd and the flash instead lands on your creatures, so you can develop the board during your opponent's turn. Because every draw adds a single counter, the parity marches predictably: two draws in a turn return you to where you started, one draw hands you the other mode. That single-counter cadence is what keeps the switch legible, since you cannot sit in both windows at once. The tension the card resolves is a classic tempo problem: how do you punish an open opponent when your hand is split between threats and answers? Kianne answers it by making you sequence draws to line up the mode you need, and by making the growth itself the thing that changes what you can cast. It rewards a deck that generates card advantage on its own terms, because every extra draw is both a bigger body and a switch thrown between two very different instant-speed plans.
