"WOOOHOO!"
I just beat the E4 on my Emulator-Diamond a wee bit time ago. It was weird.
For Aaron, I miraculously managed to set up two Nasty Plots on my Lv57 Azelf, so it just sweeped his entire team with Flamethrower+Extrasensory.
For Bertha, my Lv53 Empoleon did awesome.
For Flint, my Empoleon pwned again.
Lucian was SIIIIMPLE! I did three Nasty Plots and Flamethrower just took out all of his pokemon.
Cynthia.. was a nightmare.
Stupid Spiritomb! It had me wasting all my Empoleon's PP as I Waterfall+Surf-spammed it. I got it in the end though.
And her Garchomp.. ARGH! At least my Dialga did a great job. I took it down with a few Dragon Claws.
For Gastrodon, I just spammed Nasty Plot again and Extrasensoried it to fainting.
Roserade had the same fate, except that I used Flamethrower instead.
Lucario was an ass. He fainted many, many of my pokes. I finally got him down with Empoleon though.
Milotic was pure evil. I only had Empoleon and Dialga left after that dumbass Lucario critted my Azelf with Dragon Pulse (stupid high crit hit probability attacks!)
I decided to use Dialga. Of course, Dragon Claw did just a little bit to it (look at the line below to see what it did) and I didn't want the recharge from Roar of Time, so I kept using it.. and of course, I get a crit when I don't want it (I was just taking down its HP for a Roar of Time-KO) and she Full Restores. In the End, I get it down though. And I felt...
"VICTORY!"
My Lv52 Dialga's Dragon Claw did this much to her Lv63 Milotic:
