team comp recommendations? (no Topaz)

I don’t have Topaz and I’m not really good at making team comps myself… I was thinking someone like Ratio, Bronya, Tingyun, and Aven, but I know Ratio works off debuffs, so would it be better if I replaced one of the harmonys with Pela or Silver Wolf? almost every team recommendation says Topaz and I’m not sure what would be a good substitute :/
