Graveborn

[Gorzo]

I just found this deck and got a pretty good deal for it...
But what changes do I have to make to make it standard legal? I love the theme so I'd love to play it at my LGS...

I think except for the basic lands nothing is standard legal

{Duress} is standard legal. That's the only card other than {Swamp} that I can remember from the set that would be legal in standard.

Edit: double checked - Duress is indeed the only card from grave born that is standard legal.

Oh.... Ok... Just casual play then.:-)
So which decks should I look for which have the same kinda theme and are Standard legal?

I don't think there are any preconstructed standard decks at the moment that focus on Reanimation. If you're looking at standard only though, you'll want to have a look at event decks and Intro Packs. RTR, Gatecrash, and soon-to-come Dragon's Maze theme decks will all have standard-legal cards. Event decks are usually pretty good decks that even include a 15-card sideboard, and intro packs are moderate-decent decks + 2 booster packs (but no sideboard).

There are a couple of decks for the Golgari guild (Green/Black) that involve graveyard play, but not the same as returning creatures to life like {Reanimate} does.
