Selvala, Heart of the Wilds + Slimefoot and Squee + Phyrexian Altar + Fervor

Selvala, Heart of the Wilds

Slimefoot and Squee

Phyrexian Altar

Fervor

How it works

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

This intricate loop sets up an engine of endless rebirth, centered around Slimefoot and Squee bringing back both themselves and Selvala, Heart of the Wilds from the graveyard using the sacrifice of a Saproling token. Phyrexian Altar acts as the necessary outlet to turn your creatures into mana, while Selvala taps to refund and multiply that investment by measuring the greatest power among your creatures. Meanwhile, Fervor ensures that every time Slimefoot and Squee returns to the battlefield, its triggered ability immediately produces the required Saproling token without waiting for summoning sickness.
