How it works

1. Activate up to seven lands by tapping them, adding at least .
2. Cast Anti-Venom by paying .
3. When Anti-Venom enters, its first ability and Cloudstone Curio trigger.
4. Resolve the Cloudstone Curio trigger, returning nothing to your hand.
5. Resolve the Anti-Venom trigger, returning Great Whale from your graveyard to the battlefield.
6. When Great Whale enters, it and Cloudstone Curio trigger.
7. Resolve the Great Whale trigger, untapping up to seven lands.
8. Resolve the Cloudstone Curio trigger, returning Anti-Venom from the battlefield to your hand.
9. Activate Shilgengar by sacrificing Great Whale.
10. Repeat.

This clever loop uses Cloudstone Curio as a bouncing bridge, allowing Anti-Venom and Great Whale to repeatedly enter the battlefield and trigger each other's entry effects. As Anti-Venom brings back Great Whale, Great Whale's triggered ability untaps your lands to pay for Anti-Venom's casting cost, while Cloudstone Curio ensures the symbiote bounces right back to your hand. Meanwhile, Shilgengar, Sire of Famine lurks in the wings to convert your sacrificed creatures into a mountain of Blood tokens, ensuring this engine can easily pivot into an overwhelming finish.
