Transcendent Master

Twelve mana, paid one and two at a time across half a game, separates the body you cast from the body you were promised. The floor is honest and unremarkable: a fair-sized creature with no protection and no lifelink, the kind of thing you play when nothing better is happening. The arc is the entire pitch. Climbing into LEVEL 6-11 turns it into a 6/6 with lifelink, each swing now a meaningful life cushion; reaching LEVEL 12+ pushes it to a 9/9 and adds indestructible, an attacker that shrugs off damage-based sweepers though not exile, edicts, bounce, or toughness reduction. The cost structure is what keeps the payoff fair: every level-up is sorcery-speed only, so the climb is public and telegraphed, and an opponent gets every window between activations to kill the threat before it crosses into indestructible territory. That public investment is the real design tension. You are pouring mana into one permanent over many turns while the rest of the board still demands answers, and the creature's threat assessment shifts with each counter rather than locking in the moment it resolves. Most growth creatures of the era leaned on outside enablers, equipment, or counters drawn from somewhere else; this one carries its own scaling on its back and asks only that you survive long enough to finish the climb.
