This deck is very solid man. You have clearly put in a lot of thought for its build and in the 3 games I played against it you were dropping brutal Soul Sister + HoTP + Spectral Procession combos constantly (while Ranger of Eos comes in to add ascendants for aggression or sisters if they have been wiped).

Ajani Goldmane and Serra Ascendant of course are easy, fast beaters and its crazy how quickly you gain life and deal damage. If I were to make any suggestions, it would be to try and mainboard some Brave the Elements (I really am a fan of that card, it single-handedly wins games). When I played against your deck with mine the only thing that let me win was the colour prot it granted me to bypass all of your creatures.

You pretty much have all of the cards that you need for a WW-lifegain deck in modern. You arguably could take out Aven Mindcensor but as you said in your description you are keeping him in for your current meta. Maybe you could add a Sword of Fire and Ice or two to mix things up? Protection is IMO the most broken ability you can give a creature in magic and white abuses it better than any other color.

Other than that awesome, +1 to a fellow white mage! :)

+1 Impressive Deck. Someone would have to kill you 2 to 3 times to actually kill you.

Life gain, ugh, that's why I dread playing White sometimes. HA!

Nice Soul Sisters build -- I like it a lot. It's a very straightforward and simple strategy, but it works really well. +1
