This ingenious loop turns the top of your library into an engine of endless value, sustained entirely by the mana and triggers generated right on your battlefield. Mystic Sanctuary acts as the crucial recursion piece, returning Ghostly Flicker to the top of your library every time the spell blinks it back into play. Meanwhile, The Great Henge and Experimental Frenzy work together to let you cast that flickering instant directly off the top of your library while fueling your mana pool and drawing you through your entire deck.
