Ghostly Flicker + Mystic Sanctuary + Stonespeaker Crystal + The Lunar Whale

Ghostly Flicker

Mystic Sanctuary

Stonespeaker Crystal

The Lunar Whale

How it works

1. Activate Mystic Sanctuary and Stonespeaker Crystal by tapping them, adding 2.
2. Cast Ghostly Flicker either from your hand or from the top of your library by paying 2, blinking Mystic Sanctuary and Stonespeaker Crystal.
3. When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
4. Repeat.

This clever loop locks down an infinite sequence of spell casts and landfalls by turning Ghostly Flicker into a self-sustaining engine. You cast the spell to blink both Mystic Sanctuary and Stonespeaker Crystal, whose combined taps provide the exact blue and colorless mana needed to pay for the next iteration. As Mystic Sanctuary re-enters the battlefield untapped, its triggered ability scoops Ghostly Flicker right back off the top of your library—a maneuver assisted by The Lunar Whale, which lets you cast that exact card off the top of your library as long as it has attacked that turn.
