What kind of advice are you looking for?
More angel tokens?
Click here. This should have pretty much all of em, and as an unintended bonus, it has changelings too, which also count as angels.
The best angels you don't have?
Emeria Shepherd/
Karmic Guide could give you some reanimation.
Angel of the Ruins would be awesome since you're a little light on lands and removal.
Steel Seraph is a nice option early and late game, and supports the lifegain cards you have in here.
Mirror Entity is a straight up wincon, especially with the counters from Giada on top.
General deck advice? First, I would add at least 5-8 more lands. Maybe you could cut some of the non-angel cards (like
Raise the Alarm and
Alliance of Arms) for those? Maybe cut one of the higher cost ramp cards like
Gauntlet of Power? Also, I'd add more white sources. Maybe cut
Mirrex and
Dark Depths since they're off-theme and one doesn't give mana. I assume you'd added
Dark Depths for the combo with
Thespian's Stage/
Vesuva. It works, but it won't happen often in your deck since you have no way to find those cards. I would save that combo for a deck that has Green or Black. Definitely cut
Evolving Wilds; all it can find is
Plains, so just put a
Plains in it's place.
Then add more removal. I assume your main goal is to get angels on the field, but that won't work if your opponents are doing stronger things that you can't stop. Maybe remove
Demystify and
Erase for more flexible stuff like
Generous Gift and the new
Stroke of Midnight. They'll destroy almost anything, instead of just enchantments.
Rebuke could be replaced with
Swords to Plowshares,
Path to Exile or
Lay Down Arms. If you can find space, maybe even add all of em. All EDH decks need removal.
Lastly, at a glance,
Isochron Scepter,
Legion's Landing,
Eyes in the Skies and
Custodi Soulbinders don't seem on-theme or synergistic. And if you take only one piece of advice from me today, take this: remove
Armageddon. It's a fair card, but it makes people VERY angry. I'm guessing you wanted to blow up lands, then use
Crucible of Worlds and artifact ramp to
rebuild faster than your opponents. Again, I think it's a fair strat, but often it won't work out that way; you'll only end up prolonging the game by a lot, and your friends might not be your friends anymore
There's much more I could say, but a few of these things should help a little. Good luck.
