Put all lands with a basic land type from your library onto the battlefield tapped
How it works
Activate Perilous Forays by paying 1 and sacrificing a creature you control, searching your library for a land card with a basic land type and putting it on the battlefield tapped.
When the land enters the battlefield, Seed the Land and Amulet of Vigor trigger.
Resolve the Seed the Land trigger, creating a creature token.
Resolve the Amulet of Vigor trigger, untapping the land.
Activate the land by tapping it, adding 1.
Repeat.
This clever loop transforms a single mana into a relentless engine that strips every basic-typed land straight out of your deck. You begin by paying the activation cost of Perilous Forays to sacrifice a creature and fetch a land, which enters the battlefield tapped. This is where Amulet of Vigor and Seed the Land shine: the amulet immediately untaps your newly arrived land so you can tap it right back for the {1} needed to repeat the process, while Seed the Land graciously replaces your sacrificed creature with a fresh 1/1 green Snake token.
