6. When Great Whale enters, it and Cloudstone Curio trigger.
7. Resolve the Great Whale trigger, untapping up to seven lands.

10. Repeat.

This elegant loop relies on Anti-Venom, Horrifying Healer being repeatedly cast from your hand, triggering Cloudstone Curio each time to bounce it right back out of harm's way. When Anti-Venom enters the battlefield, its triggered ability plucks Great Whale straight from your graveyard, which in turn untaps your lands to pay for Anti-Venom's casting cost once Cloudstone Curio returns the legendary symbiote to your hand. Meanwhile, Woe Strider is waiting in the wings to cleanly sacrifice Great Whale whenever you need to reset the loop and indulge in infinite scry triggers.
