Elite Arcanist + Cabal Ritual + Chromatic Orrery + Pemmin's Aura

Elite Arcanist

Cabal Ritual

Chromatic Orrery

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.

By imprinting Cabal Ritual onto Elite Arcanist, you turn the wizard into a reusable ritual engine, letting you tap it to cast copies of the dark spell for a flat investment of two mana. Pemmin's Aura serves as the perfect untap vehicle, using its low-cost ability to refresh Elite Arcanist repeatedly as long as you can feed the loop. Once your graveyard hits threshold, each generated copy of Cabal Ritual yields more mana than the activation and untap costs demand, turning Chromatic Orrery's ability to filter any color into a boundless reservoir of infinite colored mana.
