Well that was far easier than I was expecting...
Not one casualty after the five battles, although at least three were in single figures health by the end so I suppose there was some luck that they survived.
Hodor's rather spectacular combo of Sleep Powder and Solarbeam took out all of Lorelei's Ice types, except Jynx who was clobbered by Hairball's Rest/Snore attack and finished off by the surprisingly useful Strength
Not surprising was all of Bruno's line up being annihilated by Hitchcock's Psychic as was pretty much all of Agatha's Poison/Ghosts. The only beast that I decided to give Hitchcock some help with was the lv58 Gengar, who I am pretty certain has Shadow Ball and would be quicker than my Kadabra. One quick Sleep Powder from Hodor after he survived a Sludge Bomb allowed Hitchcock to lay his Psychic smackdown once more.
So far my attempt on the Elite 4 had been straightforward but as predicted, the dragons posed a more difficult conundrum. However, after Hercules had fried Gyarados with Thunder and Adrian! had Rolled Out Aerodactyl, the combination of Rest/Snore and Strength from Hairball ripped the guts out of Lance's two Dragonairs. And then it was the big one... Dragonite. For him I decided to give the the trusty Sleep Powder a whirl and it worked straight away allowing Hitchcock to deal some heavy damage with Psybeam. Unfortunately, then there came Full Restore but through some good fortune, I was able to put the dragon to sleep again and Psybeam him once more, only for ANOTHER Full Restore to appear. But again Sleep Powder subdued him and a critical hit from Psybeam did the job.
Seeing as how I had all of my squad still around, the Champ proved rather straight forward as I had the types to deal with his array. Adrian's Rock Slide did for Pidgeot, Hercules' Surf did for Rhydon, Sleep Powder/Solarbeam/Razor Leaf did for Alakazam when he once again decided to repeatedly use Reflect and Future Sight instead fo attacking Hodor, Charizard was Rolled Out by Hairball, Egyptian finally got in on the act with a Drill Peck/Fly combo on Exeggcutor and Hercules finished things off with a Thunder attack on Gyarados.
