Vector, Imperial Capital

Black and red from one slot, no strings attached: it enters tapped, produces either color on demand, and refuses every clause that later fixing added to buy the tempo back. There is no basic-land type to fetch it with, no life-payment untap, no revealed-hand check, no count of other lands to scale off. That absence is the whole design. This is the oldest fixing compromise in the game rendered in its plainest form: you get both colors for the cost of one turn's tempo, and the trade never sweetens beyond that. Its ancestors run back through every enters-tapped common dual ever printed, and the pitch has not moved since the earliest ones. The color guarantee is the product; the turn spent tapped is what you pay for it. What that leaves is a reliable floor for two-color decks that can wait a turn and would rather not spend life or clear a rules hurdle to skip the wait. It reads as filler to a spoiler skim and plays as steady to anyone assembling a slower manabase, which is exactly the split this kind of land has always produced: uninteresting to look at, quietly load-bearing to use.
