Turnabout + Ghostly Flicker + Mnemonic Wall + Scrivener

Turnabout

Ghostly Flicker

Mnemonic Wall

Scrivener

How it works

1. Activate any number of lands you control by tapping them, adding at least 4.
2. Cast Turnabout by paying 2, untapping all lands you control.
3. Cast Ghostly Flicker by paying 2, blinking Mnemonic Wall and Scrivener.
4. When Mnemonic Wall and Scrivener enter the battlefield, they trigger, returning Turnabout and Ghostly Flicker from your graveyard to your hand.
5. Repeat.

This brilliant loop harnesses the recursion power of both Mnemonic Wall and Scrivener to continuously fish your spells back to safety. Once you cast Turnabout to untap your lands and fund your spells, Ghostly Flicker steps in to blink your creatures, which in turn use their enter-the-battlefield abilities to retrieve both Turnabout and Ghostly Flicker right back to your hand.
