Temur Devotee
A wall that fixes, not a dork that ramps. The distinction matters, because the : Add ability spends one mana to produce one, netting nothing: it converts colorless or off-color mana into a green, blue, or red pip, once per turn, and no more. What you buy for the two-mana investment is not acceleration but a durable, three-color filter bolted to a body that can actually hold a lane. Mana dorks trade their toughness for a mana per turn; this trades that mana entirely and keeps the 3/3, a blocker that survives most early aggression the way a 1/1 elf never does. So the filtering keeps coming online turn after turn while the creature blanks an attacker. The once-per-turn restriction is what keeps this honest rather than degenerate: without it, you would have a repeatable color-changer smoothing every excess mana on the table; with it, the fixing is a fixed toll, one pip per turn, which separates a legitimate mana-smoother from a runaway engine. It slots into decks that already have enough sources and need the specific colors more than the raw count. The pointed part is where the smoothing lives: a blue creature that quietly launders mana into green and red is a deliberate nudge at the color pie, handing the color that has almost never fixed for others a modest, defender-gated license to do exactly that.
