Selvala, Heart of the Wilds + Slimefoot and Squee + Tannuk, Steadfast Second + Phantom Train

Selvala, Heart of the Wilds

Slimefoot and Squee

Tannuk, Steadfast Second

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 loop turns the graveyard into a revolving door of recursive power, anchored by Slimefoot and Squee bringing back both itself and Selvala, Heart of the Wilds with the help of a sacrificed Saproling. While Tannuk, Steadfast Second hangs back to keep your team hasty, Phantom Train acts as the ultimate sacrifice outlet, consuming your creatures to fuel itself while clearing the board for Selvala to tap for a massive influx of colored mana. The resulting engine endlessly loops entrance and exit triggers to generate infinite mana, deaths, and counters.
