After a few tips this is the current working build for my Angel deck. It's being run as an aggro deck which can get Avacyn out as early as turn 4 with any another angel before it on turn 3.
The main idea is to get as much mana growth through
Ranger's Path
s, Rampant Growths, Somberwald Sage and Avacyn's Pilgrim as quickly as possible to start getting the big guns out.
Angelic Skirmisher I use to tweek each combat as neccessary.
Sublime Archangel is an obvious choice in an angel deck, especially in the early stages when you only have 1 or 2 flyers out, it can turn another 4/4 flyer into a 6/6, minimum, even more if a few of my ramp creatures have managed to stick around.
Who wouldn't want an angel that if you touch, you die.
Bow of Nylea serves a little added bonus of deathtouch, while also giving the option of giving my creature a boost, taking out a flying chump blocker, or giving a small boost to my life total, whatever's needed at the time.
And Descendants' Path is in for obvious reasons. Being a fairly tribal deck, with almost a quarter of it being Angels, this will help boost the number of creatures coming out.
Once either Akroma's Memorial or Avacyn, Angel of Hope come out, it almost always means game over.
If anybody can give any tips or ideas where I can improve this any further, it would be very much appreciated.
Cheers everyone!
