Improvised Arsenal + Crime Novelist + Krark-Clan Ironworks + Elspeth, Storm Slayer

Improvised Arsenal

Crime Novelist

Krark-Clan Ironworks

Elspeth, Storm Slayer

How it works

1. Activate Improvised Arsenal by paying 4, creating two token copies of it due to Elspeth, Storm Slayer.
2. Activate Krark-Clan Ironworks twice by sacrificing the Improvised Arsenal tokens, adding CCCC.
3. Crime Novelist triggers twice, putting two +1/+1 counters on it and adding .
4. Repeat.

This explosive loop relies on Improvised Arsenal to flood the board with Equipment tokens, a process dramatically accelerated by Elspeth, Storm Slayer doubling every token creation event. Once those copies hit the battlefield, Krark-Clan Ironworks turns them into a steady stream of colorless mana by sacrificing them for parts. Meanwhile, Crime Novelist watches the artifacts go to the graveyard and rewards you with a cascading supply of red mana and growing +1/+1 counters. You can then channel that massive mana pool right back into paying Improvised Arsenal's activation cost, letting you repeat the entire cycle to generate infinite resources.
