What Adc is good on silver division?

Something easy to play and even easier to master. My pick would be miss fortune, tristana or ashe. Players often take complicated champions that take a long time to master and just end up losing ranked games because of their lack of skill. Another important aspect of adc'ing is: farming. Focus more on getting farm early in the game. You can carry with most of adc's if you hit those last hits every time.
