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

This clever loop uses Anti-Venom, Horrifying Healer as a recursive engine to continuously recur Great Whale, which pays for itself by untapping your lands upon entry. As these creatures repeatedly bounce and re-enter, Cloudstone Curio triggers off their shared permanent types to effortlessly cycle them back to your hand without spending actual card advantage. Meanwhile, Thermopod sits on the battlefield waiting to sacrifice Great Whale for red mana whenever you need to filter your resources or fuel the loop anew.
