Xenan Xumucan Midrange (now with extra Kairos!)

10/29: Slight update to the market; seems this deck is still quite decent.

Just in time for it not to matter at all, here's my finely tuned Xenan Midrange. This deck is based on camat0's deck wlaSI1cOZXw combined with josecarlos Xumucan deck Xenan midrange (with Xumucan) to make something that can actually win midrange games AND beat control! Unfortunately, we're still in an aggro meta which makes this one a tough out, and Flame of Xulta is released on Monday, but hey, enjoy this expensive deck for 3 days. :P

As camat0 pointed out, the necessary cards for the Kairos combo are relatively few, and the combo is absolutely devastating. Just to head off some questions, I ended on Last Chance in the market because I have 8 merchants/smugglers, and the 8 power combo is the fastest to pull off.
The combo is to have a merchant/smuggler in the void and play Talir + Last Chance to summon Kairos for free. Destroy your opponent's face. Or anything else for that matter...
