Mega Diancie revenge kills Mega Pinsir quite easily if it is healthy enough to survive one quick attack and in return OHKOs with diamond storm (assuming you hit, lol) or if the Pinsir is weakened enough to knock it out with a moonblast. It can also switch into a close combat + quick attack with no hazards on the field.
