Looks good so far! good job!
May i suggest card:Faith's Shield? It seems you're going for a pro-colour theme, so I would use it as a three of, so that u can protect from board wipes/removal and get that last push through... Just a thought
actually, fetyr2004, card:Faith's Shield doesn't protect creatures from board wipes, unless it's dealing damage. cards like Terminus , Day of Judgment , and card:Black Sun's Zenith are all global effects, and will kill your creatures even if they are pro-everything. just to clear that up :P
as far as the deck, i love it. the War Falcon is beautiful synergy with the knights/crusader/paladin. i would actually run a bit more removal mainboard, though, i think.. +1 for sure tho :)
if you'd like, check out my Moral Support (B/W Exalted Tokens) :) it's centered more towards tokens, so i can take advantage of Sublime Archangel , and the black is more for removal (and Lingering Souls ' flashback). tell me what you think!
oh the one other gripe i had, playtesting yours, was seeing that double-white in time for the turn three Silverblade Paladin , Mirran Crusader or Vampire Nighthawk . if you do tweak the deck, maybe up the mana base of one of the colors a bit more to clear that up. and if you feel risky, Vault of the Archangel is fantastic :)
