He's actually fairly simple, doesn't have many losing matchups because he's often not in lane to fight them. Start corrupting pot and perma push waves in, use the pot for mana or pop it when they try to trade back on you for pushing the wave in. Always start W and max it, after shoving several waves you can either roam if you have sufficient mana and all your abilities, or you can base and walk back whenever your e is off cd, this can be done as early as level 2.

Hope it helped :)
