Anti-Venom, Horrifying Healer + Cloudstone Curio + Viscera Seer + Great Whale

Anti-Venom, Horrifying Healer

Cloudstone Curio

Viscera Seer

Great Whale

How it works

1. Activate up to seven lands by tapping them, adding at least .
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 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.
8. Resolve the Cloudstone Curio trigger, returning Anti-Venom from the battlefield to your hand.
9. Activate Viscera Seer by sacrificing Great Whale.
10. Repeat.

This clever loop relies on trading mana and creature recycling through a continuous dance of entering and leaving the battlefield. By casting Anti-Venom, you trigger its ability to pull Great Whale straight out of your graveyard, which in turn untaps your lands to pay for the next iteration. Cloudstone Curio sits quietly on the board providing the crucial bounce mechanism, letting the Whale's entry return Anti-Venom back to your hand so you can recast it all over again. Meanwhile, Viscera Seer provides a convenient outlet to sacrifice Great Whale when the loop needs to reset or pivot, tying the whole engine together into an infinite stream of triggers and untaps.
