MTG - Khans of Tarkir Cube Update 1

Another big update with the release of Khans of Tarkir.  My previous cube post had my thoughts on what I was planning on adding and I pretty much stuck to it with a few minor deviations.  I also took the opportunity to add a few things from Conspiracy and a few other sets.

Of the mechanics in Khans I added three (really only two because I only added one card)

• Outlast - Mostly added this because a few of the outlast creatures gave creatures with +1/+1 counters extra abilities.  I have a lot of ways to give creatures +1/+1 counters so these creatures would benefit those decks a lot.  The actual Outlast ability was secondary.  
• Ferocious - Works well as there are a lot of 4 power creatures in the cube or ways to get 4 power creatures.
• Prowess - Only added one card with this ability, Monastery Swiftspear, as it plays well with the Izzet Blitz archetype I have present.  Blue has no cheap Prowess creatures and I don't really think going Jeskai Blitz would work well in limited (white has a few cheap Prowess creatures).  Admittedly there is a lot more fixing in my cube so it could work.  Something to think about in the future.

On to the actual update!
