Selvala, Heart of the Wilds + Slimefoot and Squee + Fervor + Phantom Train

Selvala, Heart of the Wilds

Slimefoot and Squee

Fervor

Phantom Train

How it works

1. Activate Selvala by paying and tapping it, adding at least 1.
2. Activate Phantom Train 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 chaotic engine relies on a continuous loop of resurrection and sacrifice, fueled by Fervor granting your team immediate haste so they can dive right back into the fray. You use Phantom Train's ability to send both Selvala, Heart of the Wilds and Slimefoot and Squee to the graveyard, setting up Slimefoot and Squee's recursion ability to bring them both right back out. Each time Slimefoot and Squee enters the battlefield, it drops a Saproling token to pay for the next revival, while Selvala taps for a massive influx of mana to keep the cycle going.
