I know you asked momo but Fitz had a grand total of one post really referencing addressing creature d1. So if they're scum pair it has nothing to do with their interactions d1 and needs to he drawn entirely from d2.
Fitz originally lists not liking Red, Screen and Momo d2. Now is okay with the case on sheep from impede despite not liking impede d1. I don't think fitz is that scummy from his direct line of play but it would be more clear if he had more content. He barely posted d1 and his d2 thoughts are hard to categorize pre flip for me.
I dont think fitz is likely maf if sheep is not maf. But he could be.
Honestly gun to my head if I had to guess. 1 maf and SK left it would be Sheep and Impede. If I'm wrong about sheep I think 2nd Maf was either non existent d1 (fitz, Assemble/screen, Kop) or was on the wagon. Red/Ghost or Momo. But I doubt if we have 2 Maf that Creature was Bussed.
SK is harder if it's not Impede. Why do we think Una would have shot A50?
