The best super cell play I saw was at Arizona, quarterfinal 2 match one. (
video here)
The red alliance of 2840, 60, and 2839 had a super cell available in each corner. The first super cell was thrown into a pileup, missed the trailer, and landed on 2839's pneumatic shooter. Several seconds later they aimed and fired it into the trailer (the only robot to score a super cell at AZ, I think). To top it off, the payload specialist from the other corner scored the second super cell from over half the court away!
