How it works

1. Activate a Swamp and Forest by tapping them, adding .
2. Cast Molderhulk by paying .
3. When Molderhulk enters the battlefield, it, Necroduality and Cloudstone Curio trigger.
4. Resolve the Cloudstone Curio trigger, choosing to return nothing to your hand.
5. Resolve the Necroduality trigger, creating a token copy of Molderhulk.
6. When the Molderhulk token enters the battlefield, it and Cloudstone Curio trigger.
7. Resolve the Cloudstone Curio trigger, returning the nontoken Molderhulk from the battlefield to your hand.
8. Resolve the token Molderhulk's trigger, returning a Swamp from your graveyard to the battlefield.
9. When the Swamp enters the battlefield, Cloudstone Curio triggers, returning another Swamp from the battlefield to your hand.
10. Resolve the nontoken Molderhulk's trigger from step 4, returning a Forest from your graveyard to the battlefield.
11. When the Forest enters the battlefield, Cloudstone Curio triggers, returning another Forest from the battlefield to your hand.

This clever loop turns Molderhulk into a self-sustaining engine by taking advantage of its own cost reduction and graveyard-fetching abilities. Every time Molderhulk enters the battlefield, Necroduality doubles up your efforts by creating a token copy, which triggers Cloudstone Curio to bounce the original back to your hand for re-casting. Meanwhile, the lands cycling in and out of your graveyard fuel your mana while also satisfying Cloudstone Curio's type-matching bounces. Once you have this perpetual motion machine running, Borborygmos Enraged steps in to convert your endless stream of discarded lands into infinite damage to close out the game.
