Mines of Moria

A red source that punishes you for having nothing to lead: it enters tapped unless a legendary creature is already down, which quietly ties the land's tempo to a board state most red decks aren't building toward. That conditional is the price for a colored land in a slot that usually demands a basic, and it makes the card read less like fixing than like a payoff for a legendary-heavy shell. The graveyard sink underneath is the more distinctive machine, but it isn't ramp in the traditional sense: , a tap, and three exiled cards buy two Treasure tokens, which is a net loss of mana the turn you fire it. What you're really doing is time-shifting. You spend now, in cards and in mana, to bank two Treasures that fix into any color and stay available across later turns. The exile clause is doing the balancing work: it forces the ability to compete with any other graveyard use you have and caps how many times a game can profitably feed it, so this never becomes a bottomless faucet. The design spends the resource nobody was spending (a stocked graveyard) to smooth the resource everyone fights over, at a pace slow enough that it rewards the long game rather than accelerating a fast one. The flavor lands cleanly: you dig too greedily and too deep, and the cost is measured in cards left behind.
