Beginning tips to play Sylas

Hello, Ive recently started playing league of legends after my friends convinced me to play. For a long time Ive watched them play the game and Sylas always stood out to me as a fun champ. Now that I actually play the game Ive played a lot of games with him and he is indeed really fun to play and I want to Main Sylas. The purpose of this post is to find out what things i have to improve on, like combos, matchups, laning tips, etc. I know that things like youtube tutorials exist and Ive watched them but I really do believe that asking people that Main the champ is the better approach. Sorry for this long explanation but I thought that adding some background would be better lol. Anyways thanks in advance to those who want to help me.
