Orzhov Keyrune

A 1/4 with lifelink is the least aggressive body any of these mana rocks can become, and that modesty is the whole Orzhov thesis. The cycle answered a perennial problem with fixing artifacts: a rock that does nothing past the early turns rots in your hand, so each of these converts into a creature once the colors it produces stop being scarce. Where the aggressive members stand up evasive beaters built to close a game, this one animates a wall that bleeds the opponent a point or two at a time, every block and every swing a small repeatable life swing rather than a finisher. That defensive posture matches the grind Orzhov has always preferred. The transformation cost demands both colors at once, so the rock-into-body shift only comes online after your mana is genuinely set up, which keeps the artifact honest as a fixer for as long as you need one. The two functions are deliberately sequenced: fixing first, a hard-to-kill lifegain blocker second, the artifact staying useful from the turn it enters to the turn the board stalls. It never stops doing something, even after its fixing job is finished, and that continuity is the point of the whole design.
