Turnabout + Ghostly Flicker + Ardent Elementalist + Donnie & April, Adorkable Duo

Turnabout

Ghostly Flicker

Ardent Elementalist

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

By weaving together a recursive loop of instant-speed recursion and blinking, this engine generates infinite mana alongside endless enter-the-battlefield and leaves-the-battlefield triggers. You initiate the sequence by casting Turnabout to untap your lands, using the resulting surplus mana to fund Ghostly Flicker. This spell targets both Ardent Elementalist and Donnie & April, Adorkable Duo, exiling them and immediately returning them to the battlefield. The entry triggers of Ardent Elementalist and Donnie & April, Adorkable Duo do the crucial work of fishing Turnabout and Ghostly Flicker right back out of your graveyard and into your hand, ready to cast all over again.
