Azorius Battle for Zendikar Block Constructed (Casual)

When I was brainstorming some ideas I came up with this. I am going to explain to you how this deck works with these cards
--Mana Source
I mainly used decent mana source cards for a W and B deck, some cards in the maybe deck are likely cards for mana source but in the end I left them out
-- Creatures
-Courier Griffin
A good life source for using flooded strand
-Expedition Envoy
A good 1 mana card
-Felidar Sovereign
if you combine this card with Ondu War Cleric you can get something going...
-Guardian of Tazeem
Like Dehydrate but is both reusable and can attack
-Lantern Scout
A good rally card
-Munda's Vangard
Really good cohort
-Ondo War Cleric
infinite life source
-Sphinx of the Final Word
main damage source and decent fattie
-Stoneforge Acolyte
nice 1/2 and has a good cohort (maybe not)
--Other Spells
-Planar Outburst
nice Destruction!
-Quarintine Field
EXILE!!!
--Sideboard
-Gideon, Ally of Zendikar
good planeswalker but just didn't make the cut
-Crush of tentacles
it may be more powerfull than Planar Outburst with the Surge Cost but I didn't feel like the cost whould happen
-Kor Bladewhirl
has a nice Rally but didn't make it
-Reflector Mage
the only good thing is that it can get rid of powerful green creatures
-Serene Stewart
not that good of an ability

P.S this is my first deck so don't juge me too hard...
