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.
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.
