What Adc is good on silver division?

Search champion.gg and look at the best win-rate adcs.
Golden rule is to play something which you are #1 GOOD AT #2 well-practiced in #3 that's good in the meta.

Best ADCs according to champion.gg are quinn, missfortune, twitch, draven (in that order but it's senseless to play draven if you don't have very good mechanics, map awarness whilst catching axes and able to be oppressive in lane)
