Tried SLKR vs SLKR and both team members were impossible to beat forever. See the attached image. Note that the defending team had new DC level 15 for Night vision Rey. Other counters did not work ...
Ideas
I know her abilities. She should not be untargetable forever, only for one turn or so.
So with this DC it's a sort of infinite loop we had in the game before.
As I said, her Malevolent Lineage removes 100% TM from your team. She is using that to remove all your teams TM, WHICH IS MAKING SOMEONE ON YOUR TEAM NOT A TURN. Then if you use it, someone on their turn might not be getting a turn. See how that works?
