“I would recommend playing a PTA and Ghost combo into him as he is 99% of the time going to build straight into Adaptive Helm, causing us to deal absolutely zero damage to him mid-game. PTA pretty much counters him in every way due to dealing 8-12% & 10% extra damage from Liandries & allowing for a (E)+(W) max with BOTRK. Avoid his bush cheese level 1, keep yourself on the rivers side and watch as he (Q)'s a minion wave from them. Watch your Red/Blue he may steal through his suicide passive. It's really all about kiting his (E) slow and then avoiding his (Q) charge up. Watch out for his (6) ult from base!
“TL;DR - EASIEST LANE. DON’T LET HIM FARM.
Sion is among the easiest lanes in the game. There is nothing he can do. Just be careful level 1 as he might be cheesing your redbuff or charging up his Q in a bush. In all honesty, there is no way Sion can actually solo beat you. Your E cancels his Q as well. You can very easily dive him. Your ultimate resets off of his passive form which is good to remember. You also get your passive if you stack it on his passive form. He can escape with R in level 6 but you should have a massive lead before then.”
“Dodge his Q and you should be fine. Gets pretty tanky so might be hard to kill until you get some items. After he dies run away as his passive form deals quite a lot of damage.”
“Build Blade of the Ruined King then Black Cleaver. Sion is a skill matchup because both you you have outplay potential on each other. Renekton's dash is the main outplay method here because it bypasses Sion's slow so landing a stun Q is harder.
Because of your shield breaking W, this matchup has gotten much easier early game but you don't scale with him as well as the Spear of Shojin days.
Your goal to beat him is dash out of his Q range and use empowered W to break his shield. If he doesn't use his shield, just stun him then dash away and kill him later. Do not dash out his his Q is still up because he has a chance to lock you down for a really bad trade back.”
“One of the real counters to you! Try to survive and farm.”
“Parry his Q if he often charges it or his health bubble. You can also use it on his Ult if he uses it poorly. If he has ult and you are winning, try to position yourself on top of him towards his escape route so he cant ult away. If you land your riposte early game when he wastes Q, you should win as his attack speed is already fairly slow.”
“Sion is pretty much unkillable without jungler help. Other than that his Q is easy to dodge as well as his E, shouldn't pose much kill-pressure either way.

“Free food. Your pull cancels his Q. Your ult stops him from escaping with his ult. He does no damage and has terrible innate resistances. Your only worry is if he returns with his passive and kills you but even then, its a small chance. Just poke him down and if he DARES walk up, pull him in and kill him. Just make sure he doesn't get to CS. You don't want him to be too tanky for your team to deal with.”
“Lane should be consider a free lane but sion can be quite annoying with his abilities. Build early lifesteal to have sustain.”
“Even: This lane favours you but the enemy still has kill pressure on you.
