Hashaton, Scarab's Fist + Mind Over Matter + Elvish Regrower + The Eternity Elevator

Hashaton, Scarab's Fist

Mind Over Matter

Elvish Regrower

The Eternity Elevator

How it works

1. Activate The Eternity Elevator by tapping it, adding at least twenty .
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 The Eternity Elevator.
6. Repeat.

This clever loop turns Mind Over Matter into an infinite engine by leveraging the discard outlet to feed Hashaton, Scarab's Fist, which resurrects discarded creature cards as lethal 4/4 Zombie tokens. By discarding Elvish Regrower, you trigger Hashaton, Scarab's Fist to copy it; when that token enters, its ability retrieves the original Elvish Regrower right back to your hand. Meanwhile, Mind Over Matter's discard ability untaps The Eternity Elevator, allowing the Spacecraft to generate the massive amounts of mana required to pay for Hashaton, Scarab's Fist and fuel the entire cycle indefinitely.
