Have you considered Defy Death as a potential power play? bringing back an angel and giving it +2/+2 after you have used a board wipe could be a strong move.

Check out my deck Angel of Stupidity for some cool cards that are less known / older in addition to all the fun white playthings. I'm too lazy to type them over here, sorry.

Palisade Giant can do some cool things with Avacyn.

No Ajani Steadfast? His ult seems pretty rad in a deck like this. +1

I have a ton of suggestions based on my own mono-W deck Rune-Tail Vigilance EDH

Land:
Thawing Glaciers - solid land searching
Terrain Generator - amazing ramp
Absolute Grace / Absolute Law - cheap for a permanent effect
Blind Obedience / Crackdown - slows opponents and gains you life
Land Tax / Endless Horizons / Weathered Wayfarer - more lands
Ghostway / Faith's Reward / Rootborn Defenses - protect your board
Expedition Map - find the land you need
Leonin Sun Standard - scalable white overrun
Mass Calcify - almost a Plague Wind
Angel of Jubilation - cuts off a lot of shenanigans + anthem
Eight-and-a-Half-Tails - even more protection
Sunblast Angel - asymmetric multi-kill spell - so silly after you Angelsong an alpha strike

Heartstone to reduct that activation cost.

Platinum Emperion?
Negates life-gain as well though, but acts as a win-con being an 8/8

This... this is awesome T_____T

I thought the "beloved daughter" angle was a reference to Tales of Symphonia. +1 from me all the same.

Nah, tis a reference to Tsubasa Resevior Chronicles, Sakura was called the "beloved daughter of God" in one of the dimensions they went to because of her purity and innocence.

i love this deck too yumesama7, one of my go-to decks if someone is getting uppity ;P

it gets online so quickly, and is fairly quiet, so opponents tend to ignore me, thinking that i'm getting screwed in some way, little do they know... >=3

Yeah, the deck itself is amazing, but the backstory and TRC reference... they make me wanna cryyyy T___TAnyway, +1 from me, you deserve it :D

Ghostly Prison, Karmic Justice

wtf?

no Divine Intervention for flavour? and awesome endings?

my god, why have I never seen this card before?

I dont know, but its hilarious.

especially when someone gets it in cube.

If you can Illusionist's Bracers the Palisade Giant, you can copy its ability onto Stuffy Doll, and that hurts. >:) +1

@Nightdragon779 that doesnt work.

the bracers only work on ACTIVATED abilities, not any triggered ones. and even if this were an activated ability, you couldn't just move it around however you please.

Oh. :'( Damn.

You can use Stonehewer Giant and Pariah's Shield with Stuffy Doll to go nuclear at instant speed if you want.
Granted, that is two non-angel creatures, so you'll have to consider the likelihood of it coming together.

I've debated on including Stuffy Doll before, but the card seems to draw alot of hate, especially if there's a Pariah's Shield on it.

I'm going to give this a +1 only because of the alternative art of the Avacyn

Perhaps consider Defy Death instead of Resurrection, since most of your creatures are angels?

Reconnaissance Acts as Vigilance for your creatures after dealing damage and also can save your creatures by removing them from combat once blocks are declared. Its a sneaky card I would suggest reading up on and taking into consideration, also another great combo I like to abuse in my angel tribal deck is Seraph Sanctuary + Archangel of Thune + Herald of War :P

Mass Calcify works wonders

I love the series that you have the alternate arts for. VERY good choice. +1 from me for that alone, not to mention this looks fun as hell to play. :)
