Perilous Forays + Felidar Retreat + Lotus Cobra

Perilous Forays

Felidar Retreat

Lotus Cobra

How it works

1. Activate Perilous Forays by paying 1 and sacrificing a creature, causing you to search your library for a land card with a basic land type and put it onto the battlefield tapped.
2. When the land enters the battlefield Lotus Cobra and Felidar Retreat trigger.
3. Resolve the Lotus Cobra trigger, adding 1.
4. Resolve the Felidar Retreat trigger, creating a creature token.
5. Repeat.

This elegant chain transforms a single initial sacrifice into a cascading land-draining engine. By feeding a creature to Perilous Forays, you fetch a typed land that immediately triggers Lotus Cobra to refund the activation cost in mana, while Felidar Retreat steps in to provide a fresh Cat Beast token to feed back into the Forays. The loop cleanly extracts every single basic-typed land straight from your library and onto the battlefield, filling your board with mana and a growing army along the way.
