Hostile Hostel // Creeping Inn

The colorless mana ability is a courtesy, not the point: this is a land that eats your own creatures to become one. The transform math is what gives it teeth. Three soul counters means three activations, each costing a mana and a sacrificed creature, so the flip is a slow accrual paid for in bodies rather than a switch you throw. That deliberate ramp keeps a land-slot creature from arriving free; you fund the engine with the graveyard you fill along the way. What makes the back half more than a beater is how it feeds on the same fuel: attacking exiles creature cards from your graveyard to drain each opponent for the number of bodies exiled while gaining that much yourself, turning the corpses you spent making it into the resource that closes the game. The drain is one-sided in your favor, not a symmetrical trade; the sacrifice front end and the exile back end are the same loop viewed from two angles, and the cost of transformation becomes the ammunition after it. The phasing ability is the survival valve: rather than leaving the battlefield, the Inn phases out with its counters and any attachments intact, ducking a sorcery-speed sweeper or targeted removal while it is treated as though it does not exist, then phasing back in tapped-status untouched on your next untap step. It shares the mana-neutral land camp with cards like Faceless Haven, but where those manlands simply become bodies, this one asks you to build a graveyard worth converting.
