Activate Mystic Sanctuary and Sisay's Ring by tapping them, adding CC.
Cast Ghostly Flicker either from your hand or from the top of your library by paying 2, blinking Mystic Sanctuary and Sisay's Ring.
When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
Repeat.
This clever loop hinges on Sisay's Ring providing the raw mana needed to cast Ghostly Flicker, which then targets both the mana rock and Mystic Sanctuary to reset them. As Mystic Sanctuary enters the battlefield untapped, its triggered ability puts Ghostly Flicker right back on top of your library. From there, Magus of the Future lets you immediately cast the spell again from the top of your library, perpetuating the cycle to generate infinite landfall triggers, storm count, and artifact entry effects.
