Like Bazaar, this Vintage all-star land doesn't tap for mana by itself, so it potentially sets you back mana unless you pair it with a card like Urborg, Tomb of Yawgmoth, but its effect is well worth it: all creatures have "At the beginning of your upkeep, destroy this creature unless you pay 1." So anyone with creatures will have to commit a chunk of mana keeping their creatures alive or remove them, with the more mana they have the more they gotta pay
