Dwarven Forge-Chanter

Most prowess creatures are glass: a 1/1 or 2/1 body that grows when you chain spells but dies to any breeze in the meantime. This one inverts the math. The 1/3 frame is built to survive combat before the pump ever fires, which matters for a spells-matter deck that wants its threat alive across multiple turns of setup rather than winning a single explosive attack step. Ward for two life is the piece that changes the calculus most: opposing removal, the natural predator of any prowess creature you want to keep growing, now costs the opponent both the spell and a life payment, and the payment scales against nothing (it is a flat tax that does not care how large the creature has become). The two abilities also cover each other's blind spots. Ward protects the body during the turns you are not casting anything; prowess rewards you on the turns you are. A durable, protected threat is a rarer thing in red than a fast one, and the design is less about ceiling than about refusing to trade down: the opponent cannot spend one card to erase your investment, and every noncreature spell you were going to cast anyway makes the eventual answer more expensive to justify.
