Scion of Draco

Domain cost reductions had long been a Limited-flavored curiosity, a way to reward the five-color splash without pushing anything degenerate. This dragon takes the same discount and points it at a payoff worth building an entire manabase around. Twelve on the sticker collapses fast: two generic off for every basic land type among your lands, so a shell touching all five drops a 4/4 flier down to a couple of mana. The fixing a greedy deck already wants becomes the toll that buys the body, and the toll is cheap once the lands are rainbow. The reason to pay it sits in the static ability, which reads off your creatures rather than your lands: each one you control picks up a keyword keyed to its own color, white gets vigilance, blue hexproof, black lifelink, red first strike, green trample. A single mono-color board only lights up one clause; the incentive runs the other way from the discount, rewarding a spread of colored creatures rather than a spread of basic land types. Cost reduction as a build-around and a five-color static blanket are usually two separate cards, each demanding its own commitment. Welding them to one flier is the sly part: the discount cares about your lands, the buff cares about your creatures, and the same greedy, all-colors ambition tends to supply both. Neither static ability ever reads the same permanents, yet one build satisfies both.
