Activate Mystic Sanctuary and The Great Henge by tapping them, adding and causing you to gain 2 life.
Cast Ghostly Flicker either from your hand or from the top of your library by paying 2, blinking Mystic Sanctuary and The Great Henge.
When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
Repeat.
This loop turns a simple blink into an unstoppable engine by leveraging Madame Web, Clairvoyant to cast Ghostly Flicker directly off the top of your library. As Ghostly Flicker resets your mana sources, Mystic Sanctuary conveniently recycles the spell right back to the library's peak while entering untapped. Meanwhile, The Great Henge acts as the ultimate payoff, transforming every single iteration into a flurry of lifegain, life, and card draw to bury your opponents.
