This brilliant loop transforms simple land-and-artifact mana generation into an endless cycle of spell-casting prowess. By tapping both Mystic Sanctuary and Stonespeaker Crystal, you generate the exact mana needed to cast Ghostly Flicker, which in turn resets both permanents back onto the battlefield. As Mystic Sanctuary re-enters untapped, its triggered ability conveniently fishes Ghostly Flicker right back out of your graveyard and places it on top of your library. Meanwhile, Stonespeaker Crystal quietly provides colorless mana while also holding down the utility of clearing away graveyards if needed, and with The Reality Chip attached to a creature, you can seamlessly cast Ghostly Flicker straight off the top of your library over and over again.
