I figure in the stax-heavy metagame of the midwest, some version of Life.dec might be playable. I've always had fun with it, and I'd like to give it a shot... possibly at SCG Chicago next month. I don't have the time to do much competitive playtesting, so if anyone has any advice on how to make this deck work, it would be greatly appreciated.
Here's the decklist I've sketched out so far:
Combo:
4x Daru Spiritualist
3x Task Force
4x Nomad En-kor
3x Shaman En-kor
4x Worthy Cause
1x Animal Boneyard
Protection:
4x Duress
4x Cabal Therapy
Search:
1x Demonic Tutor
1x Death Wish
1x Vampiric Tutor
4x Academy Rector
Kill:
1x Test of Endurance
1x Form of the Dragon
Mana:
5x Moxen
1x Black Lotus
1x Mana Crypt
4x Scrubland
4x Swamp
3x Starlit Sanctum
6x Plains
Explanation:
The combo is an old one. Use the en-kor's ability to repeatedly target Daru Spiritualist or Task Force so that the toughness becomes an ungodly number. Then sacrifice the creature to Worthy Cause, Starlit Sanctum, or Animal Boneyard in order to gain that much life. Once that happens, it's all over but the crying for many decks.
I chose to go with White/Black build in order to add tutors and hand disruption. Death Wish is a nice way to go get a win condition from the sideboard after you combo out. I think Neverending Torment might be fun if the test of endurance route doesn't work. I will probably devote only two or so slots to wish targets in order to ensure a win after my life gain. It is easier to put a couple alternative win conditions in the sideboard than to waste maindeck slots on them.
Academy Rector is probably the most controversial slot on the deck. It allows me to devote only one slot each to Animal Boneyard and Test of Endurance. It's a cleric, and it can be sacced to Worthy Cause, Starlit Sanctum, or Cabal Therapy. I think Form of the Dragon will make a nice silver bullet against several decks (I'm thinking fish), but I haven't added any other enchantments to the maindeck. I thought of a single Serenity, Rule of Law, or Ivory Mask. Any suggestions here would be great.
Clearly this deck is not Tier 1, but it has surprise factor, and can go off quickly. Since I find most Smokestack/Mana Drain decks tedious to play, I am looking for an unanticipated combo. (Seriously... if anyone's going to plan for Life.dec, I'll see you in the X-2 brackets)

What do you think? Should I just play Dragon? Is there a way to make this effective in a Workshop heavy metagame?
