I just realized that the card I totally jacked this art from is an ogre and not an orc. I will fix that. Also there are examples of the Orzhov sending out hits on people's heads. Cards like Slum Reaper demonstrate this. And even if he isn't hired by the orzhov itself, I'm sure you could reasonably expect some kingpin to have grudges and a lot of disposable income.

Slum reaper seems more like they are literally collecting souls of the unguilded. Not going out to kill. Besides the Reaper is something they can explicitly control and not a sentient being.
