Breya, Etherium Shaper + Crime Novelist + Urza, Prince of Kroog + Krark-Clan Ironworks

Breya, Etherium Shaper

Crime Novelist

Urza, Prince of Kroog

Krark-Clan Ironworks

How it works

1. Activate Urza by paying 6, creating a token copy of Breya that is a 1/1 Soldier.
2. Put the token Breya into your graveyard due to the legend rule.
3. The token Breya's enter-the-battlefield ability triggers, creating two 1/1 Thopter artifact creature tokens.
4. Activate Krark-Clan Ironworks twice by sacrificing the Thopters, adding CCCC.
5. Crime Novelist triggers twice, adding and putting two +1/+1 counters on it.
6. Repeat.

By leveraging the mana-generating engine of Krark-Clan Ironworks, this loop turns the legendary copy process into a self-sustaining spectacle. When you activate Urza, Prince of Kroog to copy Breya, Etherium Shaper, the resulting token immediately feeds the legend rule to trigger Breya's entry abilities while supplying two Thopters. Those sacrificed artifacts fuel the Ironworks for colorless mana, which Crime Novelist converts into red mana and compounding growth counters with every single sacrifice.
