She is an early game Champion, who rises with jungle preasure. She is very oppresive in lane and in 2v2. All her kit is about 1 shotting people, but use her e wisely. Once she uses e she is very vunerable to dive champions. She gets outranged in Midgame, so has to play with her Team and around her e. She is easy to learn but has a high skill ceiling. Her q is very important and her laning phase is dependant on you hitting your q's. With her r she has an insane amount of Kill preasure. She nearly wins every lane. In my opinion it is a good Meta to play Syndra, she has good Items and it is much about Mid/Jungle, the game are getting shorter and shorter,and that is realy good for her

Most important phase from every Game. She has to play aggresive and poke from level 1. At Level 2 with q+e+auto she can outtrade everyone. Landing your skillshots and spacing properly are very Important. It is very hard for Syndra to comeback after a rough laning phase, cause she gets outscaled. Start with Doran's Ring and 2 Pots, and buy as much ap as possible. The best first back is for Lost Champter, after that you will be at your strongest in laning phase and can kill nearly everybody

She is very good in Midgame especially from ahead. With Ludens she has one of the best bursts in the Game and can legit 1 shot everybody. After Laning Phase ends, start grouping with your Team and go for Catches with your e. Start taking full control of the Map and try to fight in choke points, Syndra shines there with her e. You can play a bit on sidelane but do not try to fight there, you want to take good fights and prepared ones. IT is hard for her to push turrets and win fair 1v1 where she doesnt start with a q+e.

This is the time where you usually get outscaled, and it only gets worse. Stay with your Team and stun as many people as you can. Stay next to you AD-Carry and peel for you two as well with your e. You can still try to 1 shot people but they are more likely to survive and kill you after. Positioning is key and without you will be dead. Try to play around Vision and choke points
