Activate Mystic Sanctuary and Gilded Lotus by tapping them, adding 3
Cast Ghostly Flicker either from your hand or from the top of your library by paying 2, blinking Mystic Sanctuary and Gilded Lotus.
When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
Repeat.
This delightful loop relies on Gilded Lotus to generate the mana required to cast Ghostly Flicker over and over again, while Mystic Sanctuary acts as our recursive engine by fishing the instant right back out of the graveyard every time it re-enters the battlefield. To keep the momentum going, Precognition Field lets us peer into the future and cast Ghostly Flicker directly off the top of our library without needing to draw it. By continually blinking both the land and the artifact, we net an infinite surplus of colored mana and trigger any enters-the-battlefield abilities indefinitely.
