Activate Mystic Sanctuary and Mana Crypt by tapping them, adding 2.
Cast Ghostly Flicker either from your hand or from the top of your library by paying 2, blinking Mystic Sanctuary and Mana Crypt.
When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
Repeat.
This vintage-legal engine achieves infinite mana and effects by turning a single land and artifact into a self-sustaining loop. By tapping both Mystic Sanctuary and Mana Crypt to generate the exact mana required, you cast Ghostly Flicker to exile and return the pair to the battlefield. Because Mystic Sanctuary enters untapped, its triggered ability places Ghostly Flicker right back on top of your library. From there, The Reality Chip allows you to cast the spell directly from the top of your deck, letting you repeat the process indefinitely.
