GU, midrange, power from number of creatures in the graveyard.

Winning with the "Deathfed" deck requires some patience. Your deck is designed with the late game in mind, and if you rush your strategy, your opponent may just overrun you. Don't worry if you appear to fall behind early. Your biggest strength is a well-stocked graveyard, and all of your cards will give you an incremental advantage while fueling your graveyard. Once your engine is up and running, it's very difficult for any opponent to stop.

The easiest way for you to fill up your graveyard is to use spells like Mulch and Forbidden Alchemy. You'll get more resources while also getting more creature cards into your graveyard for future use—a win-win situation. You can also plunk down Armored Skaab in front of opposing creatures and get an even fuller graveyard for your trouble. Use Viridian Emissary to block and take down an attacking creature and get another land, and keep a steady stream of spells and lands coming with Merfolk Looter. You can use Green Sun's Zenith to find whichever creature you need at the moment.

You'll be well rewarded for all those creature cards in your graveyard. Boneyard Wurm keeps growing as you keep filling your graveyard. Splinterfright has the same ability, plus even fills your graveyard for you. You can create huge armies of spiders with Spider Spawning (and then flashback the Spawning later). Bonehoard is particularly strong in this deck. Even if your opponent can kill the Germ, you'll have plenty of extra creatures around to pick up the Equipment. Eventually your creatures will tower over your opponent's and you can win at your leisure.

Your main deck is tuned to face a wide variety of other decks, but your sideboard allows you to attack specific strategies. With Naturalize, you can blow up annoying artifacts and enchantments. Use Negate to counter powerful spells from opposing control decks, or Flashfreeze to counter pesky red or green spells. You can fight directdamage spells by gaining life by the boatload with Gnaw to the Bone. And of course, you can always steal opposing creatures with Mind Control.

Tweaking the deck to your own satisfaction could take it in a variety of directions. Mirror-Mad Phantasm adds a more aggressive element while still fueling your graveyard. Skaab Ruinator provides an alternative use for the creatures in your graveyard and takes the fight straight to the enemy. Or you could use Jace, Memory Adept and Jace's Apprentice to dump even more creatures in your graveyard—or turn the tables on your opponent and win by depleting their decks!
