I apologise for asking you to provide more details after you have been asked.
So currently, you have Butcher Braxton full XP and you want Xantiax Robb Cr + compliment
Just some additional info you might need.
What price do you estimate your full XP Butcher Braxton
What price do you estimate Xantiax Robb Cr to be in and what XP do you want him in.
How much in Clintz/Cards is your expected compliment.
