Mystic Sanctuary + Kefnet the Mindful + Capture of Jingzhou

Mystic Sanctuary

Kefnet the Mindful

Capture of Jingzhou

How it works

1. Cast Capture of Jingzhou by paying 3, getting an extra turn after this one.
2. Play Mystic Sanctuary to put Capture of Jingzhou on top of your library.
3. Activate Kefnet the Mindful by paying 3, causing you to draw a card and returning Mystic Sanctuary to your hand.
4. Move to your next turn.
5. Repeat.

This elegant loop lets you take infinite turns by endlessly recycling your sorcery speed spells using the land-bouncing utility of Kefnet the Mindful. When you play Mystic Sanctuary with enough Islands already under your control, its triggered ability lets you place Capture of Jingzhou right back on top of your library. Then, Kefnet the Mindful uses its activated ability to draw that very card while bouncing Mystic Sanctuary safely back to your hand, ready to be replayed on your next turn to repeat the entire process.
