Metagross rocks. I use mine in all my BF battles except the battle pyramid because of the damn status afflictions there, and the fact that items are scarce and you have a 1/5 chance of running from the extremely annoying wild pokemon. Still working on my silver symbol because of this. In Fire Red, I never bothered to train a dragonite because of the fact that it is a pain to raise Dratini from lv 21 to lv 30 (I raised a Dragonite on my last file, and it took away so much of my time that my friends were like "Dude, why the f are you not answering our calls" and leaving my answeing machine filled with such profanity.) I then found out about the handy dandy Lucky Egg and now I have a Ttar and it only took me an hour to raise because of the E4 2nd round battles, in which Mewtwo sweeps, and my Salamence also was breeded to perfection and it took me 30 mins to raise.
TCM is down so I'll tell ya firsthand, I'm at the BF. Symbols won: Luck (silver)
Currently Training: Charizard, Scizor, Salamence, Milotic, Swampert Venusaur and Crobat
