Brawl Team Compositions

Let's name some Brawlers that shouldn't be on the same team in Brawl Stars team matches (like 3v3, 5v5, etc.)? For me, I'd say Ruffs and Gene. Ruffs and Gene aren't used much by experienced players, and tend to be picked more by beginners. This often leads to significant losses when trying to beat the opposing team with skilled players, so I've chosen them as Brawlers who shouldn't be on the same team. I'm curious about your opinions.
