Galadriel, Light of Valinor + Emiel the Blessed + Zirda, the Dawnwaker

Galadriel, Light of Valinor

Emiel the Blessed

Zirda, the Dawnwaker

How it works

1. Activate Emiel the Blessed by paying 1, blinking any other nontoken creature you control except Galadriel.
2. When the creature enters the battlefield, Galadriel triggers, adding .
3. Activate Emiel the Blessed by paying 1, blinking Galadriel.
4. Repeat.
5. Once you have infinite mana, you may instead choose any of Galadriel's modes.

This ingenious loop centers around Emiel the Blessed, whose blink ability is subsidized down to a mere single generic mana thanks to Zirda, the Dawnwaker's cost-reducing static ability. Every time you blink a creature with Emiel, Galadriel, Light of Valinor triggers its alliance ability, easily netting three green mana that more than pays to keep the cycle going. Once you've generated an infinite surplus of green mana through this back-and-forth, Galadriel's other alliance options can be freely chosen to scry through your entire deck, draw every card you need, and grow your entire board into infinitely massive threats.
