Elite Arcanist + Seething Song + Mycosynth Lattice + Pemmin's Aura

Elite Arcanist

Seething Song

Mycosynth Lattice

Pemmin's Aura

How it works

1. Activate Elite Arcanist's ability by paying 3 and tapping it, casting a copy of Seething Song without paying its mana cost.
2. Resolve Seething Song, adding 5.
3. Activate Pemmin's Aura's first ability by paying 1, untapping Elite Arcanist.
4. Repeat.

This clever loop turns Elite Arcanist into a self-sustaining mana engine by imprinting Seething Song beneath it, turning a modest three-mana investment into a net gain of five red mana every single iteration. To make this setup work independently of color restrictions, Mycosynth Lattice transforms all permanents and cards outside the battlefield into artifacts and ensures your mana can be spent as any color. Meanwhile, Pemmin's Aura enchants the Arcanist, providing the vital untap ability fueled by your newly generated mana so you can repeat the process endlessly.
