Turnabout + Ghostly Flicker + Possessed Skaab + Scrivener

Turnabout

Ghostly Flicker

Possessed Skaab

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

This clever loop relies on carefully recycling your spells to generate infinite mana and effects. By casting Turnabout, you generate enough mana to fund your spells while untapping your lands, setting the stage for Ghostly Flicker to exile and return both Possessed Skaab and Scrivener to the battlefield. As those creatures re-enter, Scrivener's ability retrieves Turnabout and Possessed Skaab's ability pulls Ghostly Flicker right back to your hand, allowing you to repeat the cycle indefinitely.
