Ghostly Flicker + Mystic Sanctuary + Precognition Field + Stonespeaker Crystal

Ghostly Flicker

Mystic Sanctuary

Precognition Field

Stonespeaker Crystal

How it works

1. Activate Mystic Sanctuary and Stonespeaker Crystal by tapping them, adding 2.
2. Cast Ghostly Flicker either from your hand or from the top of your library by paying 2, blinking Mystic Sanctuary and Stonespeaker Crystal.
3. When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
4. Repeat.

This elegant loop relies on Mystic Sanctuary entering the battlefield untapped through Ghostly Flicker's exile-and-return effect, which conveniently triggers its ability to place the very same Ghostly Flicker from your graveyard back onto the top of your library. Meanwhile, Stonespeaker Crystal provides the exact color and amount of mana needed to pay for the spell each iteration, while Precognition Field lets you effortlessly recast Ghostly Flicker straight off the top of your library without ever drawing it.
