Volo, Guide to Monsters

Temur Sabertooth

Phyrexian Altar

Deranged Hermit

How it works

1. Cast Deranged Hermit by paying 3.
2. Volo triggers, copying the Deranged Hermit spell.
3. Resolve the copy of the Deranged Hermit spell.
4. When the token Deranged Hermit enters the battlefield, it triggers, creating four 1/1 Squirrel creature tokens.
5. Resolve the original Deranged Hermit spell.
6. When the nontoken Deranged Hermit enters the battlefield, it triggers, creating four 1/1 Squirrel creature tokens.
7. Activate Phyrexian Altar seven times by sacrificing the Deranged Hermit token and six Squirrels, adding 4.
8. Activate Temur Sabertooth by paying 1, returning Deranged Hermit to your hand from the battlefield.
9. Repeat.

This loop relies on Volo, Guide to Monsters to double your payload every time you cast a fresh creature, leveraging the fact that Deranged Hermit shares no types with any other creatures you control or have binned. As the Hermit and its copy flood the board with Squirrel tokens, Phyrexian Altar steps in to quietly convert those bodies and the extra Hermit into a steady stream of colored mana. Meanwhile, Temur Sabertooth provides the essential escape hatch, letting you bounce the original Deranged Hermit back to your hand so you can recast it and restart the entire engine.
