How it works

1. Declare Sophina and two other nontoken creatures as attackers.
2. Sophina triggers, creating three Clue artifact tokens.
3. Activate Ashnod's Altar by sacrificing Wormfang Manta, adding CC.
4. Wormfang Manta leaves the battlefield, causing you to take an extra turn after this one.
5. If Wormfang Manta was put onto the battlefield by Havengul Mystery, Havengul Mystery triggers, transforming itself.
6. Activate the Clue tokens by paying 6, tapping and sacrificing them, causing you to draw three cards.
7. At the beginning of your end step, Havengul Laboratory triggers, transforming itself.
8. Havengul Mystery triggers, returning Wormfang Manta from your graveyard to the battlefield.
9. Repeat each turn.
