Champs for a unranked skrub?
So I hit level 30 a while ago, and I have played ranked three times so far. I have won one and lost two, and have realized that I should probably not play high risk high reward champions during ranked, at least until my mechanics improve. I like playing mid and top lane, and I was wondering if there were any champions that an unranked pleb like me could play decently. It would be nice if they were kinda forgiving, as I am going to make a lot of mistakes. Please leave some feedback, as I am inexperienced compared to other people.

mid and
top is rather forgiving with shield and Q escape/ engage. I used Ziggs
mid to farm and push last season but he isnt very meta now. Still safe farm and pressure constant and waveclear with nice team fights and kiting potential just not easy to get kills then snowball hes passive lane then mid to late poke and seige
