Infinite Guideline Station + Cogwork Assembler + Krark-Clan Ironworks

Infinite Guideline Station

Cogwork Assembler

Krark-Clan Ironworks

How it works

1. Activate Cogwork Assembler by paying 7, creating a token copy of Infinite Guideline Station that is a 1/1 Soldier.
2. Put the Infinite Guideline Station token into your graveyard due to the legend rule.
3. When the Infinite Guideline Station token enters, it triggers, creating a tapped 2/2 Robot artifact creature token for each multicolored permanent you control.
4. Activate Krark-Clan Ironworks four times by sacrificing four Robots, adding eight C.
5. Repeat.

This clever loop leverages Cogwork Assembler to repeatedly manufacture token copies of Infinite Guideline Station, which immediately enter the battlefield and trigger their own creation abilities to flood your board with 2/2 Robot artifact creature tokens. Because Krark-Clan Ironworks is sitting on the battlefield ready to turn those newly spawned metal tokens into raw mana, you can easily sacrifice four of them to fund the next activation of Cogwork Assembler. This self-sustaining loop effortlessly pushes the legendary rule and your artifact economy to their absolute limits, generating an infinite storm of sacrifices, triggers, and colorless mana.
