Arcbound Reclaimer + Iron Spider, Stark Upgrade + The Great Henge + Krark-Clan Ironworks + Flux Channeler

Arcbound Reclaimer

Iron Spider, Stark Upgrade

The Great Henge

Krark-Clan Ironworks

Flux Channeler

How it works

1. Cast The Great Henge by paying .
2. When you cast that spell, Flux Channeler triggers, putting one +1/+1 counter on Arcbound Reclaimer and at least two additional artifacts you control.
3. Activate The Great Henge by tapping it, adding and gaining 2 life.
4. Activate Krark-Clan Ironworks by sacrificing The Great Henge, adding CC.
5. Activate Arcbound Reclaimer by removing a +1/+1 counter from it, putting The Great Henge from your graveyard on top of your library.
6. Activate Iron Spider's last ability by paying 2 and removing two +1/+1 counters from artifacts you control, drawing The Great Henge.
7. Repeat.

This loop transforms a modest pile of artifacts into an absolute engine of creation. By utilizing Krark-Clan Ironworks to sacrifice The Great Henge, you feed the grave just so Arcbound Reclaimer can fish it back onto your library, while Flux Channeler ensures counters are constantly being distributed every time a noncreature spell gets cast. Iron Spider, Stark Upgrade then steps in to convert those amassed counters into raw card advantage, allowing you to redraw The Great Henge and repeat the cycle endlessly.
