{Jokulhaups} + {Liliana Vess}
Get her on the BF, play {Jokulhaups}, then use her big ability
as opposed to {damnation}?
{Jokulhaups} totally cripples the opponent long enough for {Lilliana Vess} to do her thing
{Damnation} leaves the opponent an avenue to get creatures on the BF and do other mischief as she is ramping up
I would include {Damnation} as a stop gap if {Jokulhaups} isn't readily available to cast
I'd probably go with the classic {Nevinyrral's Disk} in case they have enchantments you need to deal with.
Nice choice but I have all of the ones that I own in my {Necropotence} deck
