Hashaton, Scarab's Fist + Mind Over Matter + Pyramid of the Pantheon + Timeless Witness

Hashaton, Scarab's Fist

Mind Over Matter

Pyramid of the Pantheon

Timeless Witness

How it works

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

This brilliant loop turns the discard outlet Mind Over Matter into an infinite engine by feeding its cost directly into Hashaton, Scarab's Fist. Each time you discard Timeless Witness to untap Pyramid of the Pantheon, Hashaton pays off the discard by bringing a 4/4 token copy straight to the battlefield. That token's entry triggers its own ability to return the original Timeless Witness right back to your hand, while Pyramid of the Pantheon's massive three-mana production easily funds Hashaton's activation fee, leaving you with endless enters-the-battlefield triggers and an infinite army of zombies.
