Perilous Forays + Pitiless Plunderer + Felidar Retreat

Perilous Forays

Pitiless Plunderer

Felidar Retreat

How it works

1. Activate Perilous Forays by paying 1 and sacrificing a creature.
2. When the creature dies, Pitiless Plunderer triggers, creating a Treasure token.
3. Resolve the Perilous Forays ability, causing you to search your library for a land card with a basic land type and put it onto the battlefield tapped.
4. When the land enters the battlefield, Felidar Retreat triggers, creating a creature token.
5. Activate the Treasure by tapping and sacrificing it, adding 1.
6. Repeat.
