This guide will ONLY go over my personal build. If you seek a build which contains more standard items then i highly suggest Elexia's Syndra, the Dark Sovereign (AP Mid Carry). (Click here to go to this guide).

Coming soon...

Syndra has two options for keystone masteries: Thunderlord's Decree and Deathfire Touch . Personally I am not a fan of Deathfire Touch on Syndra (Although i haven't really tried it a lot). As an assassin, Thunderlord's Decree allows for a much larger amount of burst damage, thus improving your capability to kill squishy targets.

This is how my usual runes go:
