Hashaton, Scarab's Fist + Mind Over Matter + Pyramid of the Pantheon + Elvish Regrower

Hashaton, Scarab's Fist

Mind Over Matter

Pyramid of the Pantheon

Elvish Regrower

How it works

1. Activate Pyramid of the Pantheon by tapping it, adding .
2. Activate Mind Over Matter by discarding Elvish Regrower.
3. Hashaton triggers, causing you to pay 2 to create a tapped token copy of Elvish Regrower that is a 4/4 Zombie.
4. When the Elvish Regrower token enters the battlefield, it triggers, returning Elvish Regrower from your graveyard to your hand.
5. Resolve the Mind Over Matter ability, untapping Pyramid of the Pantheon.
6. Repeat.

This loop turns the raw power of Mind Over Matter into an engine of continuous value, using its discard ability to feed Hashaton, Scarab's Fist and trigger the rebirth of Elvish Regrower. As the token enters, its ability continuously recycles the real Elvish Regrower straight back to your hand to keep the cycle going. Meanwhile, the mana required for Hashaton is entirely fueled by Pyramid of the Pantheon, which Mind Over Matter dutifully untaps after every iteration to keep the mana flowing.
