Really good wave clear which allows her to shove the wave in and get lane priority with ease. This is really important as she can then secure objectives with her Jungler.
Her E allows her to avoid major forms of crowd control. This makes laning easy for her and makes her quite safe when left alone.
Her Ultimate R allows her to speed up the entire team, providing an enabling force for her engagers to all-in and destroy the opposition.
Improper usage of her E will get her killed in the lane sooner or later. The spell won’t work very efficiently if the enemy has layered crowd control.
She is highly immobile, so catching her off-guard will easily translate to a kill for the enemy team. This will remove a great amount of wave clear from Sivir’s team.
Is very reliant on Critical Strike items and will be set back if the enemy manages to kill her a couple of times in the lane. She is also weaker against grouped teams, as she won’t be able to get a pick on someone with her Ultimate R and her team.

Play safe for the first few levels. You need time to come online and you shouldn’t be fighting unless you have a clear early advantage.
Constantly push and poke the enemy with your abilities. Once they’re low, you can look for an aggressive all-in. However, while kills are nice, your goal is to poke and not commit to fights.
After destroying the bottom lane tower, rotate to the mid lane and try to take that tower. This will open up the map and give your team a gold lead.
15 - 25 min
Try and stick with your Support throughout the mid-game. You’re quite vulnerable and easy to kill if you’re on your own. By staying with your Support, your survivability will increase.
Continue picking up farm in the side lanes when no team fights are occurring, but spend as little time away from your team. You need gold and XP to buy items and if you fall behind, it will be unlikely that you’ll be able to dish out damage in fights.
Look for picks with your Support/Jungler to get kills and increase your lead. If you kill a key target, you could make the call for Baron.
Just like in the mid-game, you should stick with your Support throughout the later parts of the game. Do not go around the map alone as you will die easily.
Do not play super aggressive in team fights. Just kite and auto-attack the nearest enemy champion. If you walk too far forward, the enemy will focus you and take you down.
Continue to kite in team fights and consistently adapt your positioning. Avoid standing still in fights as you’ll be an easy target.
Her early game is decent as she can waveclear pretty quickly and deal a lot of damage with her Q.
Level 6 is a massive spike as it now allows her to enable her team to collapse on targets. It also allows her to run away from threats.
The first item component will allow Sivir to deal more damage and maintain lane priority by pushing the wave infrequently.
Multiple points in her Ultimate R will just enable her to help her team pick off-targets. Other than that, she can also use it defensively.
Her mid-game potential is quite strong as she can secure picks and gain mid-priority when possible. It translates into neutral objectives.
Her first ability will be maxed out at level nine, allowing her to deal out much damage. The wave clearing will let her pressurize the enemy team really hard.
The final point in her Ultimate R will secure more picks in the later parts of the game. The goal is to ensure a pick on the enemy Support or Jungler and get a neutral objective after that.
Her overall damage will be really high during this phase of the game. She will be pretty safe due to her E and Ultimate R.
Her Q and W will be maxed out now. She will be able to dish out a lot of damage in clumped fights and will be able to push waves quickly.
