Hey, I don't think you'll lose too much of this deck's power come Theros. You're really only losing a few creatures, which doesn't seem too rough. Maybe switch out Wolfir Silverheart for two more Desecration Demon , they compliment Varolz, the Scar-Striped really well. And, when you lose Skirsdag High Priest , Strangleroot Geist , and Vampire Nighthawk , look into Deadbridge Goliath and maybe a few more non creature spells. A couple more Abrupt Decay and Putrefy couldn't hurt. I also recommend Grisly Salvage , it really helps speed things up.

You'll also be able to run Scavenging Ooze , which I think could play really well in both of our decks.

I've tried Grisly Salvage , but it was kinda slow. Also, casting a Wolfir Silverheart after a Vampire Nighthawk can really help me. Maybe I'll add some more Desecration Demon s after theros comes out. Thanks for the suggestions though.

I might swap out 2 Wolfir Silverheart for 1 more Desecration Demon and 1 more Strangleroot Geist . (If i end up with another Desecration Demon .

I was just thinking about when everything rotates out, but whatever floats your boat!

Ok. But still, I'm really considering some of the suggestions.

Right on, good luck with your deck.
