-Midlane main since season 3
-23 th best Anivia Statswise in the world: http://www.lolskill.net/top/highest-lolskillscore?filterChampion=34&filterRealm= (24.04.2016)

+Insane Teamfighting due to her W and R.
+One of the hardest power spikes after 6.
+Unique reviving passive.
+Huge Autoattackrange
-Weak early (6>)
-Slow Projectile flying speed
-High cd's

Pre 6 :
-Push as hard as possible with ur q.
After 6:

In my opinion Archeangel is not playable atm because anivia gotta a insane midgame but not the best lategame.
Comparing http://champion.gg/champion/Anivia pretty much sums it up.
