Perilous Forays + Pitiless Plunderer + Scute Swarm

Perilous Forays

Pitiless Plunderer

Scute Swarm

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, each Scute Swarm you control triggers, creating that many creature token(s).
5. Activate the Treasure by tapping and sacrificing it, adding 1.
6. Repeat.
