The "Grave Power" deck harnesses the power of lost souls, refracting them into gigantic entities and overwhelming advantages. The dead may be gone, but they're definitely not forgotten.

The key to winning with this deck is to put as many creature cards into your graveyard as you can with cards like Deranged Assistant, Mulch, Tracker's Instincts, and Armored Skaab. You can also get creatures into your graveyard from the battlefield, of course, perhaps by sacrificing Dawntreader Elk or by engaging in combat with Ambush Viper.

The fatter your graveyard is, the more you'll reap the rewards. Imagine you have just six creature cards in your graveyard: Boneyard Wurm and Splinterfright are each 6/6 creatures, you can cast the mighty 10/10 Ghoultree for just (that's less than normal), Wreath of Geists gives the creature it's enchanting +6/+6, Grim Flowering would let you draw six cards, and Gnaw to the Bone would have you gain 12 life!

While attacking with huge creatures is effective, attacking with huge creatures that can't be blocked is even better. Either Chasm Drake or Executioner's Hood can grant an evasion ability to one of your giant monsters. Alternately, you could enchant a flying creature with Wreath of Geists.

If you'd like to make the deck more consistent, you could simply add more Boneyard Wurms and Splinterfrights. The Magic 2012 card Jace, Memory Adept is another great way to fill up a graveyard, and the Innistrad card Kessig Cagebreakers is another great way to capitalize on a full graveyard since it creates a Wolf token for each creature card in your graveyard each time it attacks.
