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.

10. Repeat.

This ingenious loop hinges on a recursive dance between Anti-Venom, Horrifying Healer and Great Whale, fueled by the mana-generating engine of Ashnod's Altar and your tapped lands. When Anti-Venom enters the battlefield having been cast, its ability plucks Great Whale straight from your graveyard, which in turn untaps your lands to pay for the next iteration. As Great Whale arrives, Cloudstone Curio triggers to bounce Anti-Venom back to your hand so you can recast it, while Ashnod's Altar stands ready to sacrifice the Whale to generate a surplus of colorless mana.
