MTG Salvation

I have a deck that harnesses Grisly Salvage and I need a creature card besides deathrite shaman and besides threshhold that can harness non-creature cards that are in the graveyard. Anyone have any ideas?

You looking for casual or competitive?

There are several, but it will depend on what format you mean. Also, in the future you should post in the appropriate forum (modern, casual, standard, etc) for the type of deck you're trying to build).

lord of extinction is a decent choice for casual if that's the sort of effect you're looking for.

Phyrexian Devourer + Triskelion + Necrotic Ooze for a bunch of damage.

Or just stuff with Flashback, like Call of the Herd.

Gravecrawler and Bloodghast

Cards with Retrace, like Raven's Crime.

Thanks for the suggestions so far, I plan on making it a competitive casual for real life, so that it has the potential to beat tournament-worthy decks that pro players might use for fun but isn't going to end up in tournaments itself.
Lord of Extinction was a good one, but I already am running Varolz, and that can turn into a 14/14 pretty easily. I was thinking of something as sophisticated as Deathrite Shaman but more focused on non-creature cards or with a bigger effect than just making them lose 2 life. I will already be exiling some creatures with Varolz as well as run vengevine, so too much creature exile won't work.

any others?

• treasure find
  
• regrowth
  

You can try Terravore, it can grow pretty big once you have a stuffed graveyard. Mesmeric Orb can help act as a secondary grisly salvage that also mills out your opponent.

Terravore is ok, I use to run it in the deck, but I wish there was a version of it that cost 2 mana and wasn't over $170 and named tarmogoyf.
