Activate Mystic Sanctuary and Dreamstone Hedron by tapping them, adding CCC.
Cast Ghostly Flicker either from your hand or from the top of your library by paying 2, blinking Mystic Sanctuary and Dreamstone Hedron.
When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
Repeat.
This clever loop is held together by Magus of the Future, which lets you cast spells directly from the top of your library while keeping it revealed. By utilizing the colorless mana from Dreamstone Hedron alongside the blue mana from Mystic Sanctuary, you can cast Ghostly Flicker to endlessly blink both permanents. Every iteration recycles Ghostly Flicker back to the top of your library via Mystic Sanctuary's triggered ability, fueling an infinite engine of mana, landfalls, and artifact triggers right off the top of your deck.
