You need a bit more counter cards. How about this:
-1 Wave-Motion Cannon
-1 Seven Tools of the Bandit
-1 Destruction Jammer
+1 Mystical Space Typhoon
+2 Dark Bribe
OR if ya wana get a bit risky with your life points:
-1 Wave-Motion Cannon
-1 Seven Tools of the Bandit
-2 Destruction Jammer
+1 Mystical Space Typhoon
+2 Solemn Judgement
+1 Dark Bribe
I would advise you keep mystical space typhoon in your hand in case of a royal decree. But with the new counter cards, that should be MUCH less of a problem anyways.
