Any advice for a soul tapped deck?

I'm interested in making a soul tapped themed deck any advice? Or even a link to a thread on this?

 

Are you looking to run a split or pure UD?

 

I have a decent FW UD split that worked quite well but the hunter nerfs have killed it.
UTTERDARK Leviathan was a key rune from FW. I'm not sufficiently technically gifted to paste it here.

 

I guess it would have to be fs or fw split.

That's too bad Fentum.
