Elite Arcanist + Cabal Ritual + Mycosynth Lattice + Pemmin's Aura

Elite Arcanist

Cabal Ritual

Mycosynth Lattice

Pemmin's Aura

How it works

1. Activate Elite Arcanist's ability by paying 2 and tapping it, casting a copy of Cabal Ritual without paying its mana cost.
2. Resolve Cabal Ritual, adding at least 3.
3. Activate Pemmin's Aura's first ability by paying 1, untapping Elite Arcanist.
4. Repeat.
5. If you have seven or more cards in your graveyard, this combo nets infinite mana.

To pull off this ambitious loop, you first need Mycosynth Lattice on the battlefield to smooth out your mana requirements, allowing you to easily cast Cabal Ritual and activate Pemmin's Aura regardless of color restrictions. With Elite Arcanist holding that same Cabal Ritual in exile under its imprint, you can repeatedly tap the wizard to cast copies of the ritual for free. Finally, Pemmin's Aura provides the crucial untap engine by spending a fraction of the generated mana to untap Elite Arcanist, letting you loop the process indefinitely—especially with threshold boosting your ritual yields into a net-positive mana engine.
