Karst you have way too many stipulations on your team. Character has to support both dorm and brand (ok), has to fit in with your character appeal visually (eliminates a good portion of the cast especially trenchcoats), can't be a hero (60% of characters eliminated again), has to play anchor with a very specific assist (more characters eliminated).
You are left with Vergil who has a trenchcoat and no vertical lockdown assist, Dante a hero and trenchcoat, doom who you don't like to play with, akuma who has a ground based assist, ammy who you have difficulty with the weapon inputs and is a non villain, skrull who doesn't benefit dorm much, sentinel who just like doom you probably have an issue with playstyle, magneto who doesn't benefit brand much and Arthur who is a hero and probably compete meter wise with dorm.
