4 Phyrexian Negator
4 Priest Of Gix
4 Dark Ritual
4 Flesh Reaver
3 Ravenous Rats
3 Duress
3 Ostracize
3 Bone Shredder
4 Howl From Beyond
2 Exhume
3 Lurking Skirge
3 Phyrexian Tower
20 Swamp
Well it is fairly simple to play this deck. Turn one swamp, ritual, priest of gix, phyrexian negator! Turn two swapm, flesh reaver, attack with priest of gix and negator, and so on. Just get out as many creatures as possible. If the negator gets in a pinch sack it to the tower. Use the other cards as backup for thing that might get in your way.
3 Defence Grid
3 Perish
3 Crawlspace
3 Phyrexian Processer
3 Planar Void
I have to say that the sideboard isn't to great but it works. The defense grids makes the life of a blue lpayer a lot harder(no couintering for you!). The perishs will get all those crappy elves and those thorny's out of the way. Crawlspace will slow down weeny hordes and the like. The proccesser will help get around pro-black cards and the voids will stop all of those opalescence decks!
