I would definitely run Trouble in Pairs over Mangara, the Diplomat. Unfortunately it doesn’t come in foil and I’ve made it a point to foil out my entire Giada deck.

2 non-angel cards I have my eye on are Lost Jitte and Collector’s Cage.

With Jitte I’d probably stack counters and dump them all at once to untap a strong land like Nykthos, Shrine to Nyx or Lotus Field.

For the cage I like the idea of doing hideaway on something big like Avacyn, Angel of Hope or Serra's Emissary for board wipe protection and a big swinger on your turn. You can then reset it with Guardian of Ghirapur or something that blinks it.

Perilous_Percival : ditto, it's nice getting a trickle of angel support each set.

Lord_of_Lords : that's definitely a viable strategy. You can also try out Oketra's Monument if you haven't already to get little dudes on every cast. They come with vigilance so you can get some free attacks in while saving for a convoke spell. If you're pumping out enough tokens and have nothing to do with it then I'd also recommend Skullclamp as it's the best equipment draw. I'd take note of if you can reliably get a token producer every game before slotting it in though.

Perilous_Percival : That's an interesting one as well, it's 1CMC more than Firemane Commando but you don't need to swing with 2, just by itself and its power will definitely be greater than 6. Without a haste enabler though you won't be getting that free draw till turn 5 at the earliest if you drop it in with Giada turn 4. Firemane Commando could get you the free draw turn 4 if you hard cast her without Giada and use Giada and a 3 drop Angel to attack. Firemane Commando also has the second line which allows your opponents to draw if they're hitting your other opponents which has pros and cons. It's definitely worth experimenting with but not sure if it's a slam-dunk.

Angel of Indemnity

5W - Angel Warrior

Flying, lifelink

When Angel of Indemnity enters the battlefield, return target permanent card with mana value 4 or less from your graveyard to the battlefield.

Encore 6WW

I like this card but not sure if it'll replace Karmic Guide for me. Costs 1 more than Guide and doesn't have an echo cost. It can hit all permanent types but only CMC 4 or less, so similar vein as Serra Paragon but you can do some blink shenanigans with it. The encore effect at 8CMC is only one more than Emeria Shepherd and can hit 3 targets if all opponents are still in play and gives you 15 attack power on board, much more if pumped with Giada.
