If I may, your mana curve is way to high. I know mayael is awesome, but think about this: you cast mayael, someone burn it, you recast turn 5, same.... your kinda screwed....
If you choose to stay with those high mana casting cost creature, you NEED to play at least 35-36 lands. 
Since you have some awesome equipment, think about playing wood elves, yavimaya dryad.
You should remove your extraplanar lens.


I don't like chord calling in your deck since you don't have low CC creature
Consider those addition:
mana flare
heartbeat of spring
Look like your low on mass removal:
Auster command
hallowed burial
day of judgement
sword to plowshare
path to exile


Just my 2 cents ;)
