I'm just getting back into the game, and Angel of Serenity tickled my deck building fancy. I've got basically nothing from Innistrad block, so I'm trying to keep the stuff from there limited to common/uncommon as figure it'll be fairly easy to pick those up over the power rares from that block.

The overall plan is to use my control elements to keep the game locked down, using Augur of Bolas with Nephalia Smuggler or Chandra's -2 to keep restocking my hand until I can get out an Angel along with a Smuggler to completely lock the game down and swing for the win.

I'm iffy on the Guttersnipe as all it really does is provide an alternate win vector.

I've also considered swapping the red for black. If I do that, I get more direct kill (Murder, Tribute, etc) as well as Ravenous Rats to really lock down the game if I can get it into the later game.
