Perilous Forays + Retreat to Emeria + Horizon Explorer

Perilous Forays

Retreat to Emeria

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, Retreat to Emeria triggers, creating a creature token.
3. Activate the land by tapping it, adding 1.
4. Repeat.

This clever loop transforms a single creature sacrifice into a self-sustaining engine that plucks every basic-typed land straight from your deck. It all starts by feeding a creature to Perilous Forays, which fetches a land whose entry is smoothed out by Horizon Explorer to ensure it doesn't enter tapped. That very land arrival triggers Retreat to Emeria, instantly replacing the sacrificed material with a fresh Kor Ally token to feed back into the Forays.
