Reef Roads

A tapland whose escape hatch runs on the board state rather than on colors: it enters untapped only if you already control a Mount or Vehicle when you drop it. That check happens once, on entry, and never fires again, so playing a Vehicle the following turn does nothing for the land that already came down tapped. The untapped bonus is a reward for sequencing, for laying the payoff before you commit the land. The more distinctive work sits in the sacrifice line, unusual for a land: spend a little blue, give up the land, and get a 1/1 Pilot that saddles Mounts and crews Vehicles as though its power were 2 greater. On paper it is a 1/1; for the machinery it was built to run, it operates as a three-power body, which is the only measurement that clause cares about. A spent mana source converts into fuel for exactly the permanents its enters-untapped condition wants around, closing the loop on itself. The sorcery-speed clamp on that conversion pins it to your own main phase, shutting off any end-step ambush crew and holding the trade until a turn when parting with the land does not set you back. The design asks two jobs of one card in order: trickle blue in the early turns, then cash itself in for a pilot who runs the equipment it was built to support. A rung on the ladder, not the top of it.
