How it works

1. 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.
2. When the land enters the battlefield, Zendikar's Roil and Amulet of Vigor trigger.
3. Resolve the Zendikar's Roil trigger, creating a creature token.
4. Resolve the Amulet of Vigor trigger, untapping the land.
5. Activate the land by tapping it, adding 1.
6. Repeat.
