Ghostly Flicker + Mystic Sanctuary + Possessed Skaab + Walk the Aeons

Ghostly Flicker

Mystic Sanctuary

Possessed Skaab

Walk the Aeons

How it works

1. Activate Mystic Sanctuary by tapping it, adding .
2. Cast Walk the Aeons by paying its mana cost, causing you to take an extra turn after this one.
3. Cast Ghostly Flicker by paying 2, blinking Mystic Sanctuary and Possessed Skaab.
4. When Possessed Skaab and Mystic Sanctuary enter the battlefield, they trigger.
5. Resolve the Possessed Skaab trigger, returning Ghostly Flicker from your graveyard to your hand.
6. Resolve the Mystic Sanctuary trigger, putting Walk the Aeons from your graveyard onto the top of your library.
7. Move to your next turn, drawing Walk the Aeons during your draw step.
8. Repeat.

This elegant loop gives you infinite turns by endlessly recycling your win condition and enablers right from the battlefield and graveyard. By casting Walk the Aeons, you secure the extra turns you need, while its buyback cost isn't even necessary since Ghostly Flicker steps in to do the heavy lifting. Ghostly Flicker blinks both Mystic Sanctuary and Possessed Skaab simultaneously, allowing Mystic Sanctuary's triggered ability to stack Walk the Aeons back onto your library while Possessed Skaab's triggered ability plucks Ghostly Flicker straight out of your graveyard and back to your hand.
