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

Elite Arcanist

Brightstone Ritual

Mycosynth Lattice

Pemmin's Aura

How it works

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

This ingenious loop transforms Elite Arcanist into a self-sustaining mana engine by imprinting Brightstone Ritual onto it. Mycosynth Lattice plays a quiet but crucial foundational role here, turning all permanents into artifacts and smoothing your mana so you can freely spend the red mana generated to pay for Pemmin's Aura's untap ability. As long as you control enough Goblins to fuel Brightstone Ritual past its mana cost, you can tap and untap Elite Arcanist indefinitely. This yields infinite colored mana, alongside an arbitrarily large storm count and endless magecraft triggers to seal the game.
