Ojutai Monument

The five mana-rock cycle built on this template solved a recurring problem with ramp artifacts: their tendency to sit as dead cards once the board has stalled and the mana matters less. The fix is a second mode baked into the same object. The rock fixes two specific colors early, then converts its accumulated mana into a 4/4 flier later, so a card that would otherwise be a do-nothing in the late game becomes a clock or a blocker the moment you can spare the activation. The Dragon mode is deliberately expensive enough that you are not flipping it on turn four; it is a release valve for the flood that ramp decks invariably draw into. What separates this design from a plain mana stone is that it never stops being relevant: the fixing is always live, and the body is always waiting. The animation also leaves the artifact vulnerable to creature removal it could otherwise ignore, which is the cost of carrying a threat inside your mana base. It is a modest, honest piece of two-color infrastructure: it produces exactly the colors of its named Dragon, ramps without a body the way mana rocks always have, and tucks a finisher into the slot for the games that go long.
