Land Down Under

There are two decks I've been watching closely in the Extended metagame; Pox Rock and Green Depths. I love the destructive nature of them both, their ability to grind down an opponent or win out of nowhere.

The two decks share a pedigree of sorts, coming out of the BG Rock decks of ages past. They also share an awful lot of cards. As such I thought I might as well tinker with the next evolution of the two decks. Here it is, Land Down Under:

Here's a deck that has the insta-win capabilities of Green Depths, or the grind-it-out capabilities of Pox Rock. There are some extra synergies here as well:

* Hexmage + Jitte = good times. The Jitte triggers off the first-strike damage, so you can then shrink you're opponent's creature in response before normal damage occurs, or buff your hexmage out of death range.
* Grim Discovery + Bloodghast + Fetch Lands. You get extra extra utility out of your Bloodghasts thanks to Grim Discovery, and if you fetch the Eternal Witness with it you can also recover a removal spell, Smallpox or Jitte. You can even start to get back your man lands if you're so inclined.
* Grim Discovery + Hexmage + Dark Depths. Lose the combo? Get it back again. Can be done several times thanks to Eternal Witness.
* Smallpox + Bloodghast. Clearly a key synergy in the deck, this is part of what allows you to keep coming back and back and back and back.
* Dark Confidant + Darkblast. The ability to hit your opponent's Boros 1/1s or Elves will be crucial in the upcoming metagame.
* Hexmage + Dark Depths + Tarmogofy. Triggering the combo also happens to make your Goyf bigger.

As you don't have all the tutors, you may not necessarily have the combo-consistency of other Depths decks, but you will certainly be able to grind it out against GB depths, shut down several combo decks through hand disrution, and hopefully grind it out until your combo comes online - if your opponent lives that long.
