I mean it looks alright and I don't see why you couldn't take a few games by surprise, but it's not exactly like you're going to win an FNM with this by a long shot.
My first suggestion would be to scout out your local FNM to see how hardcore the competition is. In the event that people are all playing Tier 1 decks, well, you're probably going to lose... a lot. But, if it's more of a home-brew crowd, you could likely slide in and get some wins.
I see a few issues here:
1) You rely entirely on Angelic Accord. Literally there is no other back-up plan, shy of a monstrous, Unflinching Courage Fleecemane Lion. This is a problem, as people will catch on to your plan after Game 1 and can plan accordingly - Detention Sphere, Golgari Charm, Bramblecrush, etc etc - care of Sphere and Underworld Connections people are packing more enchantment hate in their boards than normal, making them particularly suited to deal with your plan.
2) You have a complete lack of resiliency against sweepers. A resolved Elspeth, Sun's Champion just ends the game as she can easily drop all your angel tokens while outpacing the rest of your board. Nevermind this, Supreme Verdict also pretty much just hoses you unless you can gain more life quickly.
3) This deck is SCREAMING for some Selesnya love to help out. Think about the gain you'd get from Trostani, Selesnya's Voice. Once you get an angel token, you can essentially ensure you will plop more out... populate a token, gain four, get another token... she becomes a life-gain and token generator rather quickly while also giving you a solid blocker. You'll note she also is pretty solid with Voracious Wurm.
- To this end, I would also suggest cards like Advent of the Wurm, Rootborn Defenses, and even things like Gods Willing and Brave the Elements.
4) I know they're pricey, but Temple Gardens are a must to be competitive in these colors. If you do want to go the gate route, 4x guildgates and Saruli Gatekeepers aren't a completely terrible idea.
5) I don't know that I'd run Alive // Well as it will require you to have a board presence to gain life. You could just as easily run Riot Control for the Fog effect and life gain there.
To make a long story short, go scope out your local meta to see if this could get any traction. If you're in a control heavy meta, you're screwed (same goes for Tier 1 builds), but otherwise you could likely steal a few games/rounds and likely have some fun.
Good luck!
