New to Ranked, Looking for Champion Advice
Hey everyone! I've just recently been ranked as Silver IV. As exciting as that is, playing ranked has made me realize that I still have a lot to learn about league in general. I was hoping to get some advice on what champions are viable at the moment, or to what extent you should worry about what's considered meta. Here are some of the champions I really like.

Now there's a lot of champions here I would not play in a ranked game given my current skill level with them, but I can do relatively well with them in normals. Which champions do you all think would be good for me to focus on getting to know better for ranked play? I mean to the point of setting up custom rune and mastery pages for them. Right now, I just have general runes and masteries.
Any other advice about ranked play in general is also appreciated. Thanks for the help!
