Ghostly Flicker + Mystic Sanctuary + Dreamstone Hedron + Future Sight

Ghostly Flicker

Mystic Sanctuary

Dreamstone Hedron

Future Sight

How it works

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

This clever loop starts with Dreamstone Hedron and Mystic Sanctuary supplying the necessary blue and colorless mana, with the latter conveniently leveraging its untapped entry to place Ghostly Flicker right back on top of your library. From there, Future Sight does the heavy lifting by letting you cast that very same Ghostly Flicker directly from the top of your library, restarting the cycle. By continually blinking Mystic Sanctuary and Dreamstone Hedron, you generate an infinite surplus of mana and triggers, turning the top of your deck into a bottomless engine.
