1.missingno is only found in red/blue and yellow i think, but you can trade them onto gold/silver/crystal
2.yes, i have, i advise saving the game just before you start the competition, so if you dont win you can just turn the power off and on and try again
try getting a buterfree, beedrill, or even better, scyther or pinser
those are the best pokemon, get them highest level (14 i think) and i think males are better...
