Kavaron, Memorial World

Station was introduced as a creature keyword, an engine for tapping your board to feed charge counters and unlock a bigger threat over time. Grafting that mechanic onto a red-producing land that enters tapped puts the fixing and the payoff in a single slot, and the counters only climb when you have creatures to tap and the willingness to keep them out of combat. The 12+ threshold is the real price. You are not spending mana to charge it; you are spending tempo, sequencing a sorcery-speed tap step across multiple turns while the land dribbles out one red. Hit the ceiling and the reward is a repeatable finisher: sacrifice a land to make a 2/2 Robot and give your whole team +1/+0 and haste until end of turn, converting a stalled board into a lethal swing in one activation. What pulls the card in two directions is that the charging half wants a patient, creature-dense position while the sacrifice half wants to close the game the instant you get there. It asks to be built up like a planeswalker and then emptied like a mana sink, and the fact that it costs nothing to play is the concession that pays for how long it takes to matter.
