Dimir Guildgate

The tapland tax in its plainest form: enters tapped, taps for two colors, asks nothing else of you. This is the floor of fixing, the rate every dual-land upgrade is measured against. The Gate subtype is the only thing on the card doing more than producing mana, and it sat dormant for years until a handful of designs (Gate Colossus, Maze's End, Gates Ablaze) decided to reward owning a pile of them, turning what was otherwise the most disposable land in a two-color deck into a deliberate count. Strip that subtype away and the card is functionally identical to every other "enters tapped, taps for one of two colors" cycle that fixes mana at the cost of a turn: the kind of land you run when you cannot afford anything better and the tempo loss is acceptable. The tradeoff is the entire pitch. You pay one tempo point up front, once, in exchange for never having to think about whether you can cast your spell. That bargain is generous enough to be a staple of budget and casual manabases and stingy enough to be the first land cut the moment a real dual becomes available.
