Selvala, Heart of the Wilds + Slimefoot and Squee + Umbral Collar Zealot + Mass Hysteria

Selvala, Heart of the Wilds

Slimefoot and Squee

Umbral Collar Zealot

Mass Hysteria

How it works

1. Activate Selvala by paying and tapping it, adding at least 1.
2. Activate Umbral Collar Zealot twice by sacrificing Selvala and Slimefoot and Squee.
3. Activate Slimefoot and Squee by paying 1 and sacrificing a Saproling, returning it and Selvala from your graveyard to the battlefield.
4. When Slimefoot and Squee enters the battlefield, it triggers, creating a 1/1 Saproling creature token.
5. Repeat.

This engine harnesses a clever cycle of resurrection and mana generation, anchored by Mass Hysteria to let everything act the moment it arrives. Selvala, Heart of the Wilds taps to fund the recursion costs while leveraging the creature-heavy loop, and Umbral Collar Zealot provides the crucial sacrifice outlets that feed Slimefoot and Squee back into the graveyard along with Selvala. Whenever Slimefoot and Squee re-enters the battlefield, its triggered ability conveniently provides the fresh Saproling token needed to pay for the next revival, keeping the entire sequence self-sustaining.
