The deck seems fin because of the blend of + life, posion and damage reducers. Try some stop opp: bonus and stop opp ability if you don't have them in the deck allready.
Skrumxxt or eris
Sylth or Askai
This is pioson but a sketz sacorum works really well for a defensive player
I'm guessing your going T2? try sentinel, ulu watu, and/or sakrohm. I have had the most success with those clans. If you really do prefer jungo/sak, then I strongly suggest you atleast use a leader. The problem I see with just those 2 clans is the lack of power/attack manipulation on the jungo side.
