 {Blood Artist}   {Sign in Blood}? What's the main deck idea?

[Ejazz00]

I just want a bunch of good creatures out there an be able to keep up with a lot of decks. I guess midrange agro? With  {Griselbrand} to put my mana into late game.

Although there's more mulicolored creatures due to Gatecrash, I'd go {ultimate price} over {murder}.
