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 Palinchron from your graveyard to the battlefield.
6. When Palinchron enters, it and Cloudstone Curio trigger.
7. Resolve the Palinchron trigger, untapping up to seven lands.
8. Resolve the Cloudstone Curio trigger, returning Anti-Venom from the battlefield to your hand.
9. Activate Ashnod's Altar by sacrificing Palinchron.

This elegant loop relies on Anti-Venom, Horrifying Healer entering the battlefield after being cast to pluck Palinchron right out of your graveyard, setting off a cascading chain of triggers. As Palinchron arrives to untap your lands, Cloudstone Curio uses that moment to bounce Anti-Venom back to your hand so you can cast him again, while Ashnod's Altar is on standby to sacrifice Palinchron and churn out an endless supply of colorless mana.
