Xayah is an outstandingly solid pick for climbing in silver
Like, aside from strong damage from both her auto attacks and a properly executed E, it's just the fact that she has tools that fit her liking, whether she needs to play safe and kite, or whether she wants to go balls-to-the-wall carry mode. She's a really forgiving champion that can get you out of a bind if you solemnly vow to NEVER use your ult aggressively.
Are one of these guys on you?

etc.
Most other ADC's would pop like a balloon at the exact moment they touch you, but you can just tap your ult really quickly, slowly skedaddle backwards, and boom. safety. I used to not like Xayah when she first came out for some reason. I only decided to play her in Ranked when I faced a team that begged me to make the most of that ult, and since I'm not absolute bronze garbage, I caught onto her straightforward kit and managed to carry most of my games really hard. Unless the shitty matchmaking gives me a bronze 4 Shyvanna Jungle who goes 3/20 by the end of the game.
I miss when I was gold 2, back before the preseason fucked me
