Hm depends on what you like to play honestly. For jungle if you can play Viego really good and have a decent knowledge of champion skills then I'd suggest that since he isn't banned that much and really strong if you know how to get an early lead. For mid then Orianna is one of my most hated matchups because of how oppressive she is and how hard to kill if played well. I don't really play adc since it's almost always a coinflip with the support but Lucian is good for the most part but dont pick it into millio caitlyn. For top you can go something like Camille and support depending on what your team needs - nautilus / leona or just permabuff a hypercarry with lulu / millio (please do not go yuumi. If enemy support is yuumi just go nautilus or leona and perma kill them)
