First off, no said psychic decks would be invincible after Gym Challenge came out. Just a whole lot better. Ever heard of Resistance Gym? Wigglytuff might be able to K.O Sabrina's Alakazam, but not before losing half its life( if Wigglytuff got 1st hit). You can't really use MP Mewtwo to make psychic look bad, because Mewtwo is also psychic. Sure ditto can destroy psychic Pokemon, but he has the risk of being destroyed himself, because ditto also shares the psychic weakness. And also, I don't know what your saying with Sabrina's Golduck, since it is water, not psychic. 
 
 
Thats all for now. Love notes, hate mail, suggestions, send here, because I'd love to here about it. cmcknight@interhop.net seeya,  Damon  Martin
