Honestly, i don't know how you always do so well with this deck. It looks really sweet, but everytime I try it, it's just awful. I get run over by aggro decks, I get humiliated by control and bigger decks, or I get color screwed.
Personally if I want to play midrange, praxis, xenan, hooru, elysian or a plate deck all seem like better options. Maybe it's different in best of 3, but for ladder I don't see this deck preforminh
At least from my experience playing TJP Mid, you win Aggro matchups through your cheap yet quality statlines making your board hard to punch through (and Commando lifesteal if he somehow doesn't get Torched on sight), while the control matchup is won through your beefy Aegis 4 drops forcing 2-for-1 on removal, Stand Together protecting the rest of the units, and Kothon/Siraf ults making free board presence. Opposing midrange decks feel like the diciest matchups, as that's mostly solved through drawing enough removal to answer threats that are too big for your units to handle.

And very smart use of the sideboard vs. In Cold Blood.
