Improvised Arsenal + Crime Novelist + Krark-Clan Ironworks + Bard, King of Dale

Improvised Arsenal

Crime Novelist

Krark-Clan Ironworks

Bard, King of Dale

How it works

1. Activate Improvised Arsenal by paying 4, creating two token copies of it due to Bard.
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 setup transforms Improvised Arsenal into a self-replicating mana engine by leaning heavily on the token-doubling replacement effect of Bard, King of Dale. When you activate the Arsenal, Bard steps in to double your production into two token copies, which you immediately feed to Krark-Clan Ironworks for a massive influx of colorless mana. Meanwhile, the constant flow of sacrifices turns Crime Novelist into a powerhouse, generating a steady stream of red mana and growing larger with every iteration to fuel the loop indefinitely.
