Apprentice Wizard + Pemmin's Aura + Chromatic Orrery

Apprentice Wizard

Pemmin's Aura

Chromatic Orrery

How it works

1. Activate Apprentice Wizard by paying 1 and tapping it, adding 3.
2. Activate Pemmin's Aura's first ability by paying 1, untapping Apprentice Wizard.
3. Repeat.

This elegant engine transforms Apprentice Wizard into a powerhouse mana producer by pairing it with Pemmin's Aura. Because the wizard's ability yields three colorless mana while the aura's untap ability costs only a single blue mana, you net a surplus of two mana with every single loop, generating infinite mana of any color thanks to Chromatic Orrery's ability to wash your mana freely.
