don't bring mew or mewtwo, i know they level up freaky fast but their stats are not-so-great, bring Charizard (heat wave pwns 2 much), OR Electrode (SUPERB sub lvl.20 moveset, learns sonicboom at lvl.1 which deals 55HP SET damage, also he learns it AGAIN at lvl.15, if ever you're lucky enough to find a link box, you could link them together to deal a total of 110HP SET damage, you could ALSO try using Alakazam (EXTREME starting stats of def. and sp. def.) Also, try to beat a lot of pokemon in each floor so you could lvl. up and get stronger because opponent's lvl. increases in the upcoming floors and once you haven't reached a certain level before going to a specific floor, you're TOAST
