Trazyn the Infinite + Basalt Monolith + Timeless Lotus

Trazyn the Infinite

Basalt Monolith

Timeless Lotus

How it works

1. Activate Trazyn using Timeless Lotus's ability by tapping it, adding
2. Activate Trazyn using Basalt Monolith's ability by paying 3, untapping Trazyn.
3. Repeat.

Trazyn the Infinite serves as the ultimate vessel for this loop, relying on its passive Prismatic Gallery ability to inherit the activated powers of every artifact resting in your graveyard. With Timeless Lotus sitting quietly in the bin, Trazyn gains the legendary lotus's ability to tap for a full rainbow of colored mana. Meanwhile, the presence of Basalt Monolith in your graveyard grants Trazyn an untap ability for three generic mana. Because the Monolith's untap cost is cheaper than the mana generated by the Lotus, you can endlessly cycle between tapping for all five colors and paying to untap Trazyn, generating an infinite supply of both colored and colorless mana.
