Another card from MTG Salvation, it looks like the zombie tribal decks across all formats are going to get a boost in an effective 1cc zombie.
This card is amazing. As it stands, the options for 1cc zombies were Diregraf Ghoul, Sarcomancy, or Carnophage. Sure, this zombie can't block and it only has 1 toughness, but because it can just keep coming back over and over, it's value this zombie brings above the others isn't even close. Gravecrawler is just so much better than the rest. In fact, if your deck features some self-mill, the value found in this card goes up that much more. Which brings me to my next point...
...this card is just begging to be put into my Innistrad Constructed BUG Zombie Deck. Once Dark Ascension is released, the first thing I'm going to do is replace the Diregraf Ghouls with four copies of Gravecrawler. It's going to be great.
