Mystic Sanctuary + Vedalken Mastermind + Capture of Jingzhou

Mystic Sanctuary

Vedalken Mastermind

Capture of Jingzhou

How it works

1. Cast Capture of Jingzhou by paying its mana cost, causing you to take an extra turn after this one.
2. Play Mystic Sanctuary.
3. When Mystic Sanctuary enters untapped, it triggers, putting Capture of Jingzhou from your graveyard onto the top of your library.
4. Move to your next turn, drawing Capture of Jingzhou during your draw step.
5. Activate Mystic Sanctuary by tapping it, adding .
6. Activate Vedalken Mastermind by paying and tapping it, returning Mystic Sanctuary from the battlefield to your hand.
7. Repeat.

This elegant loop takes advantage of Mystic Sanctuary's landfall-style trigger to continually recycle your spells, letting you chain extra turns indefinitely. By casting Capture of Jingzhou, you earn the subsequent turn needed to draw it right back off the top of your library. The real magic, however, relies on Vedalken Mastermind to bounce Mystic Sanctuary back to your hand every single rotation, bypassing the usual land-per-turn limit and ensuring the Sanctuary can re-enter untapped over and over to keep the sequence going.
