Molderhulk

Cloudstone Curio

Necroduality

Seismic Assault

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.
12. Activate Seismic Assault twice by discarding the Swamp and Forest, dealing 4 damage to any target.
13. Repeat.

This clever loop turns the graveyard-discounting cost of Molderhulk into an engine for infinite damage by leveraging a cascade of triggered abilities. When the original Molderhulk enters the battlefield, Necroduality steps in to double your investment by spawning a token copy, while Cloudstone Curio orchestrates a permanent-bouncing dance that lets you effortlessly pick up your main copy and cycle lands. As those lands continuously enter and leave the graveyard, they fuel Molderhulk's recursion and feed a discarded supply of fuel directly into Seismic Assault to blast your opponents away.
