I have three principle Angel decks, with the creatures falling under one of the categories of protection, life, or strength. Any that don't are just classed "miscellaneous" and thus, I will generally use these in whichever deck they best compliment. I also try to keep support cards within the Angelic theme as well (Glorious Anthem, for example, because it looks and seems reasonably angelic), though sometimes I stray a little bit for the sake of effectiveness. I still juggle the cards around to try and get the most effective mix, however, so I don't always form decks that strictly follow one of the three categories.
I also have Serra Avatar. Serra is an Angel, therefore, in my book, her avatar counts as being Angelic, despite not strictly being an Angel. The same goes for Angelic Page, which is a spirit, of course.
Also, I must point out, I will never, ever touch Platinum Angel just out of principle. I have a friend who has no less than THREE Platinum Angels in his Artifact Deck of Stupidness (tm), and I want nothing to do with that monstrosity of a card.
Anyway, here is the list of Angels that I own, from memory.
ANGELS OF PROTECTION
- Akroma, Angel of Wrath
- Pristine Angel
- All of the Voices (All, Truth, Law, Reason, Duty and Grace).
ANGELS OF LIFE
- Angel of Mercy
ANGELS OF STRENGTH
- Radiant, Archangel
- Angelic Page
MISCELLANEOUS
- Angel of Retribution
- Tormented Angel
- Haunted Angel
- Wayward Angel
The angelic support cards I have are:
- Angel's Feather (Artifact)
- Angelic Favour (Instant)
- Akroma's Blessing (Instant)
- Serra's Hymn (Enchantment)
- Glorious Anthem (Enchantment)
- Worship (Enchantment)
- Serra's Blessing (Enchantment)
- Serra Aviary (Enchantment)
To compare this against, I have compiled a list of all of the white Angels I could find. It may not necessarily be a comprehensive list of all white Angels in Magic, but I trawled through various websites and have yet to find any others to add to the list. I didn't include non-white Angels as I only play a pure white deck, and I compiled the list to help me in collecting my Angel decks.
The exceptions are Iridescent Angel and Guiding Spirit, both of which are white/blue.
It also has a fairly good listing of Angel support cards in there (instants, enchantments, artifacts, etc).
