Ghostly Flicker + Mystic Sanctuary + Precognition Field + Mana Crypt

Ghostly Flicker

Mystic Sanctuary

Precognition Field

Mana Crypt

How it works

1. Activate Mystic Sanctuary and Mana Crypt 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 Mana Crypt.
3. When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
4. Repeat.

This vintage combo achieves an infinite loop by leveraging Ghostly Flicker to continuously reset and reuse your mana source and recursion engine. With Precognition Field granting you the ability to cast instant and sorcery spells right off the top of your library, you can cast Ghostly Flicker to exile both Mystic Sanctuary and Mana Crypt. When Mana Crypt returns to the battlefield, it taps for the exact amount of mana needed to cast the spell again, while Mystic Sanctuary's landfall-style trigger puts Ghostly Flicker right back onto the top of your library just in time for Precognition Field to cast it once more.
