Activate Mystic Sanctuary and Stonespeaker Crystal 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 Stonespeaker Crystal.
When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
Repeat.
This clever loop puts the top-deck manipulation of Magus of the Future to work by repeatedly casting Ghostly Flicker to blink both Mystic Sanctuary and Stonespeaker Crystal. Each iteration lets the entering Mystic Sanctuary place the recently cast Ghostly Flicker right back onto the top of your library for easy re-casting, while Stonespeaker Crystal provides the mana needed to keep the cycle going.
