Overall I think that team looks nice, aside from are two bug types it seems to be a good, well balanced team.
As for my team when I beat UM; it was Hemlock, a Decidueye with Spirit Shackle(I think, if not False Swipe), Leaf Blade, Brave Bird and Sucker Punch; Dusk, a Dusk Lycanroc with Stone Edge, Brick Break, Fire Fang
(I started playing to late to get the one from the event so it ended up with the US Fang move) and Crunch; Zourzorua, a Zoroark with Night Daze, Nasty Plot, Flamethrower and Focus Blast; Sharp, a Sharpedo, I think she had Aqua Jet, Ice Fang, Crunch and Poison Fang, can't remember exactly; Volca, a Larvesta, can't remember it's moves but I think he had Absorb at that point, like I say I can't remember and lastly Stinger, a Poipole which if I recall correctly had Dragon Pulse, Nasty Plot, Sludge Wave and some other move that I forgot
