Ghostly Flicker + Mystic Sanctuary + Skullwinder + Walk the Aeons

Ghostly Flicker

Mystic Sanctuary

Skullwinder

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 Skullwinder.
4. When Skullwinder and Mystic Sanctuary enter the battlefield, they trigger.
5. Resolve the Skullwinder 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 ingenious setup chains together to lock down infinite turns by continuously recycling your spells from the graveyard. You kick things off by casting Walk the Aeons to grant yourself an extra turn, while Ghostly Flicker acts as the engine that blinks both Skullwinder and Mystic Sanctuary back into play. When Skullwinder hits the battlefield, its triggered ability plucks Ghostly Flicker right back out of your graveyard, and Mystic Sanctuary's static land type requirements easily satisfy its own triggered ability to place Walk the Aeons squarely back on top of your library for your next draw step.
