Ultron, Machine Overlord

Every tribal lord makes the same trade, and this one makes it plainly: a body that fits the curve, an anthem that rewards you for flooding the board with the right creature type, and no further text to complicate the math. What sets the frame apart is the tribe it names. Robots and Constructs are not a creature type with a deep back-catalog of support, which means this fills the anchor slot for a tribe that had no lord to build around. The +2/+2 lands on other Robots and Constructs you control, so the deck it wants is one where the token-makers and cheap constructs are already artifacts by default, and every one of them jumps a full size class the moment this resolves. The flying is not decoration: a 4/4 evasive lord that pumps everything beneath it turns a wide artifact board into a clock rather than a stall, since the ground creatures it buffs can trade up while it swings over most blockers. As a design it is deliberately conservative, a static anthem with no death-trigger safety valve, which means the whole board deflates the instant it dies. That fragility is the cost of the payoff: build the go-wide construct shell it asks for, and losing one 4/4 flier undoes a turn of accumulation.
