MTG Combo: Amulet of Vigor + Omnath, Locus of Rage + Perilous Forays

This is a damage combo that is only limited by the number of basic lands in your deck or the remaining life of your opponents (whichever comes first). It begins with all three permanents being on the battlefield. Start by playing a land. This triggers Omnath's landfall ability, creating an elemental token. Then, tap that land to pay for Perilous Forays to sacrifice the elemental token. This causes Omnath to dish out 3 damage at a target of your choice. Then, the land you search for will enter the battlefield, it will become untapped by the Amulet, and it will cause another elemental to be created. You can then repeat the process by using the new land to sacrifice the new token. Continue until your opponents are dead or you run out of basic lands.
