What Adc is good on silver division?

Learn TRISTANA so you can escape easily .. The biggest hyper-carry late game , and is so easy to play! Also Miss Fortune!

you wanna go for mid game and early game power. So champs like lucian and mf are good here. As well as a few others.

if you know vayne mechanics then you can hit up gold in 1-2 days, vayne cant be countered in silver

I would say trist her lane is good and you got an escape

Whatever you're best at. Don't be a meta slave. Play what you enjoy and what you're comfortable with. You'll earn more wins learning the kit of your favourite champion inside out than just towing the meta line.

Jhin, Twitch and Miss fortune

but ADC is not all u need an good support as well.

You should try Cait with dark harvest, she has lane pressure and you scale hard considering the length of games in low elo

In my opinion Xayah is one of the best adc right now and with herultimate (making heruntargetable) makes for a good escape in dangerous situations

caitlyn, lucian or vayne, maybe xayah or jhin but jhin is difficult to play i think

Definitely Lucian, it's the most powerfull ADC, it's a good carrier and even if you loose your lane you can get back to game later with a good focus on farm. Good luck
