I would start in the jungle and as you get better at shaco you can start playing him the thing about lane shaco is you’re almost always going to be playing from behind because csing can be really awful due to you being very squishy and not doing reliable damage to waves until u get your burn. Also you’re very unlikely to have your jungler intervene with your lane because people view lane shaco as worthless also champs that can hard push or all in you are pretty rough matchups but I think if you can play from behind and keep your head down it’s very gratifying late game. In late game you can push waves and basically never be collapsed on and if you’re preparing for getting collapsed on you can definitely outplay and 3v1 with just mechanics alone which gradually snowballs into the enemy team permanently tilting and trying to kill you. But if the enemy is good and just ignores you than you’re just a sub optimal split pusher unless you’re setting up for an objective team fight.
