Gallifrey Council Chamber

Tribal fixing built for a lineup that spans two creature types at once. It enters untapped and taps for colorless immediately, so it never costs you a turn no matter what else is in hand; that baseline is the floor the rest of the card sits on. The second mode is a filter with a leash: any color, but spendable only on Time Lord or Alien spells and their activated abilities. Roping the flexible mana to a specific tribal payoff is what pays for it. A land that produced any color unconditionally would be a five-color staple, welcome in any greedy pile that wanted a free rainbow source; pricing the fixing this way means it only rewards decks that actually commit to the theme. The surveil-on-entry is the sweetener: it smooths draws and stocks a graveyard the moment the land lands, which matters more in a deck already threading two tribes together than in one that just wants untapped colorless. What keeps the card off the downside side of the ledger is that basic function is never on the line: the colorless tap is always live, and everything past it is upside for a deck built around the intended payoffs.
