Brilliance Unleashed + Lithoform Engine + Krark-Clan Ironworks + Zirda, the Dawnwaker + Dynaheir, Invoker Adept

Brilliance Unleashed

Lithoform Engine

Krark-Clan Ironworks

Zirda, the Dawnwaker

Dynaheir, Invoker Adept

How it works

1. Cast Brilliance Unleashed by paying 4. Choose its second mode, targeting any artifact card in your graveyard.
2. Holding priority, activate Lithoform Engine's second ability by paying 1 due to Zirda and tapping it, targeting Brilliance Unleashed.
3. Holding priority, activate Krark-Clan Ironworks by sacrificing Lithoform Engine, adding CC.
4. Resolve the Lithoform Engine ability, copying Brilliance Unleashed, targeting Lithoform Engine.
5. Resolve the copy of Brilliance Unleashed, returning Lithoform Engine from your graveyard to the battlefield as a 3/3 Robot artifact creature.
6. Repeat from step 2.

This ingenious loop turns a recursive sorcery back on itself by leveraging Zirda, the Dawnwaker to slash Lithoform Engine's activation cost down to just one mana. By sacrificing Lithoform Engine to Krark-Clan Ironworks for colorless mana mid-chain, you generate the fuel needed to copy Brilliance Unleashed—which conveniently reanimates Lithoform Engine as a 3/3 Robot artifact creature ready to repeat the process. Meanwhile, Dynaheir, Invoker Adept sits on the battlefield quietly tying the loop's logistical framework together, allowing your active engines to fire off endlessly without missing a beat.
