Perilous Forays + Amulet of Vigor + Felidar Retreat

Perilous Forays

Amulet of Vigor

Felidar Retreat

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, Felidar Retreat and Amulet of Vigor trigger.
3. Resolve the Felidar Retreat 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.

This clever loop turns a modest sacrifice into a massive, battlefield-sweeping engine by feeding itself the very resources it generates. You begin by paying {1} to sacrifice a creature to Perilous Forays, fetching a land from your library. As that land enters tapped, Amulet of Vigor immediately steps in to untap it, leaving it fresh and ready to tap for the exact mana you need to fuel the Forays again. Meanwhile, every single land drop triggers Felidar Retreat to spawn a fresh 2/2 white Cat Beast creature token, ensuring you never run out of fodder to feed back into Perilous Forays until every basic-typed land in your library rests safely on your battlefield.
