Just a few thoughts for sideboard or mainboard depending on what you think:

Honor of the Pure since you are running mono-white.

Elite Inquisitor might be a good choice if Midnight Duelist is replaceable...its an extra plains yes, but it has pro-Werewolves/Vamps/Zombies.

Angel of Jubilation might be a nice angel to add as well.

Honor the Pure is a great idea, as is Elite Inquisitor. I might sideboard inquisitor, I put Duelist in specifically because he's a single mana drop.

Also, going to probably pull out Scroll of Avacyn since I have a good bit of lifelink without it.

Added a maybeboard with other cards I have in the Avacyn set that I could drop in.

Depending on what you drop scroll for...have you thought about Riders of Gavony? granted its a 4 drop and only affects humans, but still...

Increasing Devotion is good too if you can drop Timely Reinforcements mainly because those are humans, while timely is soldiers. It is a little high on mana, so if you wanna keep it low use Gather the Townsfolk. Also, if you want one drop human, why not Champion of the Parish? (those two in combo are fun!)

Oh! Solid point on Timely Reinforcements. Thanks again for the recommendations!

I forgot about Thraben Doomsayer as well. He just pops out human tokens or chump blockers each turn... or Mikaeus, the Lunarch either of those are good as well.

Yeah no problem!...I'm also working on a deck...or rather trying to revamp my BW Human Sacrifice deck to a human/angel deck. also for a gamble you could try to grab an Entreat the Angels...but its only good if you get its miracle cost...a 7 cmc for 2 4/4 angels is rough (non miracle)

Might just be me, but I thought Voice of the Provinceswas a bit overcosted.

I watched a couple of people play them at Prereleases and they always seemed rather ineffective.

So, if you're looking into adding Increasing Devotion, I'd drop the Voice.

Yeah...I agree with that...I'm not planning on using it in my human/angel deck...which you can take a look at W Humans/Angels (just need to get a few more cards) if you want to see my take on a human angel deck. also I forgot about Defy Death! pretty nifty for angels (or a human if you REALLY want that particular human back on the field).

Avacyn, Angel of Hope is a maybe...it would be a late game drop or earlier with Herald of War. I only use her because of the game changing aspect she brings.

Gideon Jura might also be a good thing to put in. Hes great in general but he turns into a HUMAN soldier...so he can pump up Champion of the Parish as well.

Angelic Overseer is a must as well (in my opinion).

I agree with ElementTitan, you gotta run Angelic Overseer. Humans and Angels is literally the deck type that card is made for.

Ok, made some changes ... added Gisela, Blade of Goldnight took out the Avacyn Scrolls as well as timely reinforcements. Changed the mana situation and dropped in Angel of Jubilation.

So this is all based on the cards I presently have. Going to look into the remaining cards you guys recommended and maybe pick them up pending on how this plays now.

Additional thoughts?

I would swap the Midnight Duelist for a couple Champion of the Parish and perhaps a few Timely Reinforcements to get some tokens out quick and give him some beef.

Timely Reinforcements wont beef up Champion of the Parish .

I borrowed a few of the cards on this deck. Because of that +1 :)
