Turnabout + Ghostly Flicker + Greenwarden of Murasa + Donnie & April, Adorkable Duo

Turnabout

Ghostly Flicker

Greenwarden of Murasa

Donnie & April, Adorkable Duo

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 Donnie & April and Greenwarden of Murasa.
4. When Donnie & April and Greenwarden of Murasa enter the battlefield, they trigger, returning Turnabout and Ghostly Flicker from your graveyard to your hand.
5. Repeat.

This elegant loop relies on generating enough mana with your lands to cast Turnabout, which untaps them all so you can fuel the rest of the turn. Once you're floating the necessary resources, Ghostly Flicker steps in to exile both Greenwarden of Murasa and Donnie & April, Adorkable Duo, blinking them right back onto the battlefield. Because Greenwarden of Murasa's entry trigger conveniently loops back for your instant and sorcery spells, and Donnie & April, Adorkable Duo handles recursion for your other vital pieces, you can endlessly recur both Turnabout and Ghostly Flicker to fuel infinite mana, storm count, and entry triggers.
