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

Hashaton, Scarab's Fist

Mind Over Matter

Graveshifter

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 Graveshifter.
3. Hashaton triggers, causing you to pay 2 to create a tapped token copy of Graveshifter that is a 4/4 Zombie.
4. When the Graveshifter token enters the battlefield, it triggers, returning Graveshifter from your graveyard to your hand.
5. Resolve the Mind Over Matter ability, untapping The Eternity Elevator.
6. Repeat.

This intricate loop is powered by Mind Over Matter, which converts the simple act of discarding a creature into a versatile way to untap your permanents. By feeding Graveshifter into this discard engine, you trigger Hashaton, Scarab's Fist to resurrect the changeling as a formidable 4/4 Zombie token. That token's entry ability immediately returns the original Graveshifter from your graveyard back to your hand, replenishing your ammo. Meanwhile, the mana produced by The Eternity Elevator easily funds Hashaton's copy fee while leaving plenty of surplus energy to fuel the rest of the engine indefinitely.
