Kalemne, Disciple of Iroas

One of the experience-counter commanders from the cycle that introduced the mechanic, and the one built around a single restrictive payoff: she only grows when you cast creatures of mana value 5 or greater, the most expensive bracket the experience commanders ask for. That constraint is the whole shape of the card. The counters never come off, so she compounds across a game, but the entry fee per counter is steep enough that she rewards a top-heavy curve full of giants and bombs rather than the value engines other experience commanders enable. A 3/3 that already starts with double strike and vigilance is swinging for six and holding back nothing; each counter pushes that toward a clock that ends games in two hits, and double strike means every +1/+1 counts twice in combat math. The vigilance keeps her honest as both threat and blocker while you assemble the heavy hand she demands. Where the other experience designs of her era ask you to chain cheap permanents or sacrifice for triggers, she asks the opposite question: can you afford to keep casting big, and is the payoff worth the slow ramp toward each counter. She is the experience commander that hands a deck full of fatties a wincon attached to its general, turning a clunky curve into the point of the deck rather than a liability.
