I like it!  A few things that stand out to me:
 
1.  The whole faction has a nice cost\benefit feel.  Lots of command cards with powerful abilities mixed with potential drawbacks, and several units that have great strengths and severe weaknesses.  I really like the leadbelchers in this regard, as their range limitation is nicely balanced by their stamina and their damage potential.
 
2.  Balancing "core" type units with stamina will be tough--ironguts, for example, with guard, charge, and stamina, are going to be absolute beasts in a brawler role.  They are costed fairly high at the moment, so this might be fine, but stamina is just so good that it is hard to tell until I see them on the table.  The army will be very difficult to kill, that much is certain.
 
3.  The freeze keyword is interesting, as it opens up some very interesting possibilities in scrums, but is relatively worthless in single combat.  It would definitely be best used with ranged attacks if available. 
 
4.  Not sure I would ever take the scrap launcher.  Ability to wound itself, range limitations compared to other siege weapons...but interesting counterpoint with stamina, toughness, impact.  Again, hard to say without seeing it in action.  Mournfang also feel underwhelming to me, but again, you are walking a fine line with that stamina, so maybe they are priced correctly.
 
You have enticed me enough that I am thinking about proxies and a little test battle...keep up the good work!

Version 1.1 is here
I introduced two new abilities - Freeze (Thundertusk) which comes with new token and Ogre core (small disks solution)
I created one new unit - Yhetees - otherwise Tundertusk'd be the only one with Freeze ability.
I created one Gnoblar unit. (Surprisingly I found another good artwork, but realized I prefer only one Gnob)
I boosted some units, I nerfed some, changed prices (in fact almost all units are at least a bit modified)
I reworked two cards: Aura- It's d6-1 an hits even allies, and added Guard 1 to Wall of Guts.
Thanks for suggestions!
I'm curious what you think about the new changes!

Since there is no expansion, I decided to make my own
I chose Ogres and I'm looking forward to your comments and ideas!
Enjoy!
