Ghostly Flicker + Mystic Sanctuary + Elsha of the Infinite + Stonespeaker Crystal

Ghostly Flicker

Mystic Sanctuary

Elsha of the Infinite

Stonespeaker Crystal

How it works

1. Activate Mystic Sanctuary and Stonespeaker Crystal by tapping them, adding CC.
2. Cast Ghostly Flicker either from your hand or from the top of your library by paying 2.
3. Elsha's prowess ability triggers, giving it +1/+1 until end of turn.
4. Resolve Ghostly Flicker, blinking Mystic Sanctuary and Stonespeaker Crystal.
5. When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
6. Repeat.

This mesmerizing loop hinges on the battlefield manipulation of Ghostly Flicker, which resets both Mystic Sanctuary and Stonespeaker Crystal simultaneously. As Mystic Sanctuary re-enters the battlefield untapped, its triggered ability swoops in to place Ghostly Flicker right back onto the top of your library. From there, Elsha of the Infinite steps in to let you cast that exact same spell off the top of your library with flash, while also growing larger each time thanks to prowess.
