I'm not a big person to show stat by stat on things I've seen. But so far i have soloed misaki, mcabe and youko. I have also did a double master list with youko and asami.
Youko needs her mask to be built in for her blackmail action. Pass tokens I have found are not as big other than turn 1 and 5. Giving her a obey unless they discard 2 cards would be great
Misaki is solid. Getting some anti armor would be great but maybe would be over the top. She's good where she is.
Mcabe is right now in a weird place. His crew is pure scheme. Besides seider their is no punch. Whatever is coming from the new faction for him I hope they are tuff.
My youko and asami was ok. I should of brought more stones. If I run it again I'll probably start with 7 activations for a bigger cache and I would imagine it would be super strong. I like where the summoning power is. Not to strong but not to weak. It's a happy medium.
With playing These masters each twice I still do not believe I have unlocked anything. Maybe further learning them will show me something else but for now the he seems to be in a alright place
