How it works

2. Play Mystic Sanctuary.
3. When Mystic Sanctuary enters the battlefield untapped, it triggers, putting Time Warp on top of your library from your graveyard.
4. Activate Meticulous Excavation by paying 2, returning Mystic Sanctuary from the battlefield to your hand.
5. Move to your next turn, drawing Time Warp during your draw step.
6. Repeat.
