From reading the article "Bust Out the Soap, It's the Simic" on the MTG website, the last creature in the little game in the article is obviously a preview for Coldsnap and, from the text revealed when you click the link labelled "More", that poison counters will be making a return in Coldsnap.

Scroll all the way down to the bottom. It's the last entry in the game.

Yes, the more awkward the Ultimus, the better Magic becomes.

So, you don't have a win condition, aside from DSC? What happens when that should fail?

Is your win condition Black Vise?

How do you plan to stay alive long enough to play these 3CC and 4CC enchantments?

The Meddling Mage problem is a good point.

I believe I've really settled on DA. Three copies means I can Intuition for some card-drawing or have plenty to pitch to Bazaar. A second Lim-Dul's Vault gives me deck manipulation and something to pitch to FOW.

I don't want to cut off-color moxen. They're there for the crazy, second-turn win hands.

EDIT: Alternatively, a Vault and a DA can be repalced with a Chain of Vapor and possibly Mystical Tutor.

Whoops, yeah, Ancestral should be in there.

For alternate kill, I was considering Eternal Witness, but I really am not familiar with that kill mechanism.

In putting together Dragon for a tournament, I find myself wondering what should go in the last four slots in my deck. I find myself partial to draw spells, especially spells that have great synergy with Intuition. That means AK or DA. Alternatively, Careful Study provides a discard outlet while digging through the deck. I suppose I should include some copies of Complusion, in case of Bazaar going off-line. I'll post the list and would love to hear thoughts about what belongs in Dragon. Forgive the lack of a sideboard, as my friends and I have yet to get that far into planning.

I don't believe that it holds a candle to Tinker. It's essentially Tinker for twice the cost.

Thanks to Oath, Dragon's classic win condition, the good Ambassador, is thwarthed by Gaea's Blessing. Alternatively, one can Ancestral his opponent to death, but another elegant solution has been given us from Dissension: Rakdos Guildmage.

Rakdos Guildmage B/R B/R
Creature -- Zombie Shaman
3B, discard a card: Target creature gets -2/-2 until end of turn.
3R: Put a 2/1 red Goblin creature token with haste into play. Remove it from the game at the end of turn.
2/2

The inclusion of such a kill requires just one land capable of producing red mana. This has advantages over Sliver Queen and Caller of the Claw in that they can swing on the turn they're created, dodging any sorcery speed removal. It has a slight advantage over Shivan Hellkite, in the odd case someone plays some manner of protection like CoP: Red, among other things.(Though,why are you playing such jank?) They wouldn't have enough mana to protect themselves, and it requires considerably less thought than stacking each damage individually. And in the odd chance some Workshop or Welder deck is running PlatAngel, the guildmage shoots it down, along with the Welder.

Well, am I off my rocker?
