Activate Mystic Sanctuary and Dreamstone Hedron by tapping them, adding CCC.
Cast Ghostly Flicker either from your hand or from the top of your library by paying 2, blinking Mystic Sanctuary and Dreamstone Hedron.
When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
Repeat.
This fascinating loop is all about recycling Ghostly Flicker to endlessly blink your mana sources and set up your library. Dreamstone Hedron provides the heavy-lifting of colorless mana to pay for the spell, while Mystic Sanctuary acts as the crucial engine piece that puts Ghostly Flicker right back onto your library when it enters the battlefield untapped. Meanwhile, The Lunar Whale lets you keep tabs on the top of your library and allows you to play that flickering spell over and over again. By repeating this process, you generate infinite mana and trigger effects to overwhelm your opponents.
