I'm making some lists for the upcoming tournament I'm having in my city and with the ideas came this: Namurr is a disguised wildcard. Follow me in this idea. Namurr counts as a Ghulam for Fireteam composition and also we have the Special Fireteam "up to 4 Janissaries + 1 Namurr" so we can translate this to "up to 4 Janissarieas + 1 Ghulam"?
That being said, the Ghulam fireteam is pretty flexible, and you could have any combination of 0-5 Ghulams, 0-5 Naffatun, 0-5 Khawarij, 0-2 Namurr, 0-1 Tarik, and/or 0-1 Leila as a core.
