left in the tourni will battle untill only one is left with 6
Pokemon each, Then the Trainer left will have to battle the Elite

Cities
ok First off, you have to be in a City with a Pokemart to Buy
Items. Pallet town is the only City without a Pokemart. Every
Citie is Unique, you can Catch certian Pokemon in Certian Areas,
like you can't Catch a Gengar in Pallet. You can only Catch a
gengar in Pokemon Tower in Lavender, ect.
It takes 2 Days on foot to get from city to city, 1 day with a
