Pure Power (Skill Swapped from your team, then back to Shuckle) +6 Attack Power Trick Shuckle holding Metronome on the 5th turn of Rollout having used Defense Curl, and scores a Critical Hit (you can Baton Pass a Focus Energy) hitting a -6 Defense Shedinja.
I believe that's the most 'powerful' damage modifying combination possible.
