Starlit Sanctum

Cleric tribal got a payoff land here, and the split between white and black halves is the design tell: this is the sacrifice-your-board card for a tribe that was built to be sacrificed. The two activations read the same creature's stats differently, white scaling the lifegain to toughness and black scaling the loss to power, which quietly rewards a deck running bodies that are lopsided in one direction. A high-toughness wall cashes out for a big life swing; a heavy attacker converts into reach once it has finished pressing damage. The colorless mana ability means the land is never a dead draw when you have no Clerics to feed it, but its real job is to give a tribe full of small, expendable bodies a way to convert the back end of a game into inevitability: every creature on the board becomes a deferred drain or a buffer against burn. The constraint that holds it in check is the sacrifice itself, since each activation costs you a creature and the toughness or power you cash in leaves the battlefield with it. It is an engine that runs on attrition, and it only pays off in a deck deep enough on Clerics to keep feeding it without emptying out.
