The Eternity Elevator

Untapped, it is a five-mana rock that produces three colorless, a Basalt Monolith rate without the untap trick, and unremarkable in that mode. The whole design lives in the climb: Station converts your board's power into stored charge counters, letting you tap a fatty and dump its power onto the ship, then repeat across turns until the total crosses twenty. Cross that threshold and a second mode wakes, and the Elevator taps for as many mana of one color as it holds counters. What the card is really doing is laundering combat statistics into ramp. Power that would otherwise attack or block becomes fuel instead, and creatures parked on defense earn their keep by feeding the ship. The ascent is deliberately taxed: getting from three colorless to a payoff worth twenty counters means tapping down your own creatures, spending board presence you cannot recover that combat, and doing it only as a sorcery so the opponent watches every rung of the climb. That telegraphed slowness is what keeps a repeatable multicolor mana faucet from being free; the reward scales with how much you have already committed. The result wants a wide, high-power board rather than a lean one, because the Elevator is less a fixing solution than a way to convert an overwhelming battlefield into an overwhelming mana base.
