Westvale Abbey // Ormendahl, Profane Prince

Colorless mana is the whole cost of admission here, and that is the genius of the trap: it slots into almost any deck as a free source, then patiently waits for the board state that makes it lethal. The token-making ability turns a stalled position into a reservoir of bodies, each Human Cleric bought for a point of life; the sacrifice clause cashes five of those bodies in for a 9/7 that arrives untapped and swinging the same turn, flying over a clogged board and gaining life as it connects. The sequence is what makes this dangerous rather than fair. A defensive deck grinding out tokens behind a stalled ground can suddenly fold the whole pile into Ormendahl, Profane Prince and end a game its opponent thought was a stalemate. Indestructible on the back face means most of the cheap removal that would answer a land's worth of investment simply does not function: the demon shrugs off damage and destruction alike, and dealing with it demands exile or a bounce-and-counter plan held in reserve. The lineage is the creature-land taken to its furthest conclusion. Where most manlands flip on a single activation and stay vulnerable, this one demands a built-up sacrifice engine and pays it off with a finisher that is nearly unkillable. It asks only that you survive long enough to feed it, then spends five creatures and a heap of mana at the exact moment the door opens.
