What solo que champs to play to carry

So, I love Yasuo but at the beginning of the season i hadn't played him in a while so i started off like 2/5 or like 3/5. Anyway, I have heard that high skill champs are bad at low elo which i am. however, since going 3/5 with yasuo I'm now 14/10. So basically, after a little practice I've won my last 11/15 games with him. I was wondering if it would be a bad idea to keep playing him or not, other than my last defeat with him which tbh nothing i could do I've been winning.
