Ya pretty much just Warstorm Surge and Sheoldred trying to make a combo thing with that you know like Rescue from the Underworld something like that
Babassoonist's suggestion about transitioning over to Jund seems like a good idea. Finding more cards that will fill your grave and recur cards from your grave are a good idea. Ramp will also be a good consideration since the focus of your idea is at the 6 and 7 mana range (and you should include something like
Rune-Scarred Demon to tutor the parts of the combo you need). Ramp will also allow you to put in some fatties as an alternate game plan/win condition and will provide some big triggers on warstorm. Looking at cards that increase your draw/filter would be good (not to mention chump/filler cards that are low on the CMC curve to clog up the board and allow you to transition into a late game where you can start your combo). Red can also be considered part of your removal package (instead of going the control route - just burn them out). Here are some cards you might consider:

Bloodghast,
Fling and
Undying Evil have nice synergy.
Shadowborn Demon also has nice synergy with Sheoldred (and can combo with a lot of ETB cards - even something like
Pelakka Wurm can become a twisted form of card draw/life gain).
Hopefully there's enough suggestions/ideas here to get your brain buzzing and building (and we'll see ya over in the Jund thread
). Just remember though that getting your 'combo' on line is expensive/slow and if it does come on line, games won't last longer than a turn or two (since you'll win right away).
