The Fire Crystal

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 2 due to Forensic Gadgeteer 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.
