Strategy
As most of "my" decks (Cecil speaking) this is an extremely expensive deck. This is packed with rares. So if you're on a budget, you may just be reading and not trying this one out. Especially trying to get ahold of Coat of Arms. The balance of elves and enchantments help speed the deck up, so as for casting costs, this is bearable and can hold it's own fairly well.
This is another very VERY strong thug deck. The more players there are, the stronger this deck usually becomes. This is not a fast deck, and multiple player games can be a great way to stall. However, even in single duels, this is a horrible deck to play against.
Your angels will be doing the majority of the attacking of course, but with Coat of Arms out, even the Elves can have a little fun too. :) With many angels out receiving many bonuses with Coat of Arms, it is possible to wipe out multiple players in single attacks, and still have your angels block.
Now, just remember, you don't want to play Coat of Arms if the opponent also has a theme deck, like ... Knights. :) If they have more knights than you do (or snakes, etc.) and they could easily kill you in one or two turns, you should hold off on playing it until you have enough angels to support yourself.
Other than that, the Blueprints speed your deck up, and the Aviary just helps you out a lot more. That's about it. But when you play this deck, you'll understand just how powerful it is, and how soon you will need to kill some artifacts...
