Brilliance Unleashed + Lithoform Engine + Krark-Clan Ironworks + Samut, Tyrant Smasher + Forensic Gadgeteer

Brilliance Unleashed

Lithoform Engine

Krark-Clan Ironworks

Samut, Tyrant Smasher

Forensic Gadgeteer

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.

This intricate loop turns recursive spell-copying into an infinite engine by leveraging Brilliance Unleashed to constantly resurrect the very piece that multiplies it. With Forensic Gadgeteer discounting its activation cost, Lithoform Engine copies the initial spell to bring itself back from the graveyard as a 3/3 Robot, while Krark-Clan Ironworks feeds the loop by sacrificing that newly returned artifact for mana to pay for the next copy. Though Samut, Tyrant Smasher and its haste-granting presence may be riding along for the ride, the synergy between the rest of the board lets you endlessly recycle artifacts to generate boundless triggers of every kind.
