Destroy all creatures opponents control during each turn
How it works
When an opponent controls a creature, activate your commander using the ability granted to it by Street Urchin by paying 1 and sacrificing an artifact.
Crime Novelist triggers, adding and putting a +1/+1 counter on it.
Resolve the ability from step 1, dealing 1 damage to the targeted creature and destroying it due to your commander's deathtouch.
When the creature dies, Revel in Riches triggers, creating a Treasure token.
