What Adc is good on silver division?

You can honestly play anyone until d5 with little to no issues if you take the time to learn the champ and how to play each matchup well enough. For beginners though I'd recommend MF, Tris, Cait, and Varus. All are really reliable right now and don't require skill at all. Ashe is also really easy, but I feel like the other ones I mentioned would be better picks.
