You asked for a solid uu team. I'll give my best
IIRC you really liked bandile in gen6 and I have a team based around it. If you wish some explanation on the team, how it deals with UU common threats or something(which I think you won't need at all, but I'd love to help you if you want), feel free to contact me.
