I know my Pokemon are legal because I sav them myself, I do not use traded Pokemon. And I cannot reply on computer chat during a battle because I play in another room, since my router signal is otherwise too weak.
Hippowdon has an attack stat of 260, Mew has 236 Sp. Att. They run no offensive AVs. I don't use damage calculators but those are the stats and I really don't see what you are complaining about. I used legal moves with legal stats, if it doesn't seem right them perhaps the problem is your Alakazam.
1. Didn't I didn't rage quit, I gave fair warning.
2. Ran damage calcs on both Mew and Hippowdon and for the damage of each they had to be max spec def and HP. Hippowdon had to have at least 100 attack EVs to OHKO.
3. If you knew that you're pokémon were legal you would have said something in chat instead of waiting until I left.
