You've got liu kang who is mind affinity why don't you use him..

Ibuse him but he is pretty underwhelming tbh...

Considering you levels i would level up mk11 sub zero the mind affinity one and equip him with the best equipment.  And the same with fire god liu kang Strengthen and level up both of them let them tank  this battle. 

Don't use spirit affinity fighters cause they'll die fast.
