Unquestioned March

[XeroShifter]

Alright so each month I am gonna try to make a new deck (personal challenge to myself.) Basically I got into the habbit of playing one deck for too damn long, and then stopped buying cards for a few years (right after fifthdawn) so im a bit behind in my collection.
Anyway, so this is the deck for March, ironically..... its named Unquestioned March, because of a card in it called Unquestioned Authority, and its a soldier deck.
I am looking for pointers here, so pls help me out, a deck is no good if it... well if its no good...

Cards

Plains x25
Advance Scout x2
Ardent Soldier x4
Benalish Trapper x2
Daru Stinger x2
Enlistment Officer x2
Frontline Strategist x3
Gerrard Capashen x2
Gustcloak Runner x4
Astral Steel x3
Blessed Reversal x2
Blinding Light x2
Coat of Arms x2
Crusade x2
Holy Light x3
Humility x3
Isochron Scepter x3
Lashknife Barrier x2
Raise the Alarm x2
Temper x2
Unquestioned Authority x3

Basically the deal here is, I sap their creatures (humility, holy light) while buffing mine (Crusade, Coat of Arms, that kinda thing)

If you read over each card you can see the general feel of the deck, I bring in weaklings they dont care about, but suddenly they are weak too, and now im buff...

I Have also considered adding
Parapet
Defensive Maneuvers
and a few others.

The deck totals 75 cards, any suggestions?
