Perilous Forays + Seed the Land + Horizon Explorer

Perilous Forays

Seed the Land

Horizon Explorer

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 untapped due to Horizon Explorer.
2. When the land enters the battlefield, Seed the Land triggers, creating a creature token.
3. Activate the land by tapping it, adding 1.
4. Repeat.

This ingenious loop is entirely self-sustaining thanks to the clever interplay between your board's permanents. By feeding a creature to Perilous Forays, you fetch a land that instantly enters untapped because of Horizon Explorer, which in turn triggers Seed the Land to replace your sacrificed sacrifice with a fresh Snake token. Since that fetched land can tap for the exact mana needed to pay the Forays' activation cost, you can repeat this cycle to pull every single basic-typed land straight out of your deck and onto the battlefield.
