Mystic Sanctuary + Capsize + Time Warp

Mystic Sanctuary

Capsize

Time Warp

How it works

1. Cast Time Warp by paying 3, getting an extra turn after this one.
2. Play Mystic Sanctuary to put Time Warp on top of your library.
3. Cast Capsize for its buyback cost by paying 4, returning Mystic Sanctuary to your hand.
4. Move to your next turn.
5. Repeat.

By taking advantage of Mystic Sanctuary's ability to recycle spells when it enters the battlefield untapped, you can loop your key spells indefinitely once you control three other Islands. Casting Time Warp grants you the extra turn needed to replay Mystic Sanctuary, which places Time Warp right back on top of your library where you can draw it again. Meanwhile, Capsize keeps the engine going by utilizing its buyback cost to return Mystic Sanctuary safely to your hand, allowing you to replay the land every turn and secure an unbreakable lock on the game.
