Black white life shenanigans

http://deckbox.org/sets/483074

Above is my black white life gain/drain deck
It is 70 cards and I am playing it casually.

I would like to get it down to 60 if possible.

The deck is centered around control using pacifism, sign in blood, silence, tnacious d etc.
My win con is angelic accord + The vizkopas
Or angelic accord + some ing else with life link.
Obzedat is in there is well for late game use

Alternatively, I can use the guildmage + exquisite blood + any of my other creatures with life link for infinite profit.

Nighthawk for discouragement, and a bunch of enchantments including sphere of safety and the one that makes their spells tapped for total domination.

Looking for ways to improve this and make it actually useful and not just a good idea.
Thanks.

Ps sorry for any typos. In a hurry lol
