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 Peregrine Drake from your graveyard to the battlefield.
6. When Peregrine Drake enters, it and Cloudstone Curio trigger.
7. Resolve the Peregrine Drake trigger, untapping up to five lands.

This clever loop uses Anti-Venom, Horrifying Healer's casting requirement and entrance trigger to pull Peregrine Drake straight out of your graveyard, fueling your mana supply by untapping up to five lands. As the Drake enters, Cloudstone Curio's triggered ability lets you bounce Anti-Venom back to your hand so you can recast it all over again. Meanwhile, Umbral Collar Zealot provides a convenient sacrifice outlet to bin the Drake if needed, letting you endlessly repeat this cycle to generate infinite sacrifices, enters-the-battlefield triggers, and surveil from the Zealot's ability.
