Activate Mystic Sanctuary and Sceptre of Eternal Glory by tapping them, adding 3.
Cast Ghostly Flicker from the top of your library by paying 2, blinking Mystic Sanctuary and Sceptre of Eternal Glory.
When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
Repeat.
This ingenious loop harnesses the top-deck mastery of Experimental Frenzy to cast spells directly from your library, turning your deck into your hand. By leveraging Sceptre of Eternal Glory's boosted mana production alongside Mystic Sanctuary's landfall-style recursion when it enters untapped, you generate more than enough blue mana to recast Ghostly Flicker over and over. Each iteration of Ghostly Flicker resets both lands and artifacts, allowing Mystic Sanctuary to continuously place the instant right back on top of your library to fuel the next cycle.
