Idris, Soul of the TARDIS + Pemmin's Aura + Timeless Lotus

Idris, Soul of the TARDIS

Pemmin's Aura

Timeless Lotus

How it works

1. Activate Idris using Timeless Lotus's ability by tapping it, adding .
2. Activate Pemmin's Aura's first ability by paying , untapping Idris.
3. Repeat.

This ingenious loop comes together by using Idris, Soul of the TARDIS as a cunning vessel: when Idris enters the battlefield, its Imprint ability exiles Timeless Lotus, granting Idris all of the exiled lotus's activated and triggered abilities—including the ability to tap for five different colors of mana. Once Pemmin's Aura enchants this newly powered-up Idris, you can tap it to generate your rainbow of mana, and then spend a sliver of that blue mana to activate Pemmin's Aura's untap ability. By looping this untap-and-tap sequence infinitely, you can flood your mana pool with endless white, blue, black, red, and green mana to cast whatever spells you desire.
