Turnabout + Ghostly Flicker + Eternal Witness + Scrivener

Turnabout

Ghostly Flicker

Eternal Witness

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 Eternal Witness and Scrivener.
4. When Eternal Witness and Scrivener enter the battlefield, they trigger, returning Turnabout and Ghostly Flicker from your graveyard to your hand.
5. Repeat.

This hypnotic loop achieves infinite mana and spell-casting by recycling its core pieces over and over again. You kick things off by tapping your lands for mana, then casting Turnabout to untap them all so you have the resources to keep going. Next, Ghostly Flicker banishes both Eternal Witness and Scrivener from the battlefield, only to immediately return them. Because Eternal Witness and Scrivener trigger upon entering the battlefield, they scoop Turnabout and Ghostly Flicker right back out of your graveyard and into your hand, ready to be cast again.
