This vintage-legal engine relies on the synergy of sacrificing and replaying your lands to push Lithatog to astronomical proportions while generating infinite landfall triggers and mana. Conduit of Worlds provides the crucial engine room, allowing you to continually play lands directly out of your graveyard. Meanwhile, Fastbond removes the traditional restriction on your land drops so you can repeat this sacrifice-and-replay loop as many times as your life total allows, with Lithatog gladly devouring the land each time to fuel its endless growth.
