Archmage of Runes

Cost reduction and card draw have lived in separate creatures for a long time: one body to make your spells cheaper, another to refill your hand after you cast them. Stapling both onto the same frame is the point here, because the two abilities feed each other. The discount lets you chain spells you could not otherwise afford in a turn, and each of those spells replaces itself, so the tempo you gain by casting more never costs you the cards to keep casting. That loop is what makes this more than a straight Baral, Chief of Compliance analog: the reduction alone shortens your spells, but the draw trigger keeps the shortening from emptying you out. The 3/6 body is doing quiet structural work too. Six toughness sits above the common red burn thresholds and shrugs off most early attackers, so the creature is built to survive the turn it lands and start compounding rather than trade off on arrival. That defensive stat line is the concession that pays for the engine: a five-mana wizard that dominates a game if it lives has to be hard to kill by damage without being hard to remove by exile or bounce. What it represents is the maturation of the spellslinger payload from a card that rewards volume into one that manufactures it.
