Have good Pokemon with good moves at high levels. And a lot of revives, full heals/full restores and hyper/max potions.
just train your Pokemon each to lvl 55 and you should have no trouble
There is no easy way to beat the Elite Four. You have to level up your Pokemon and use the right types of Pokemon against each of the elite four (i.e. don't use a fire-type Pokemon against water-type. Use electric instead). I recommend level 60 or so for the Elites. Good luck!
The best way to trade i guess wuld be to 'MIGRATE' from LeafGreen, in Pal Park to do this you need to beat the elite four and get the national pokedex
the way to get Eneti and the other legendary dogs is after you beat the elite four they become wild Pokemon
he can be found all over kanto after you beat the elite 4.the only way you can get it is as if you picked squirtle
use good Pokemon that's the only way
use cheat codes
You have to beat the elite four and then go to cerulean cave and then you go all the way through then at the end is mew two and you have to catch it that is it
you should have beat the elite four then go on your way to catch mew two then play with friends on the cable or try to get a golden or light Pokemon
theres a way you go on mtmoon then you get out then you go to the girl in front of cerulian cave she will say i will let you in if you beat the elite four and then when you go in the cave and battle lugia and mewtwo.
Beat the elite for many times and let your Pokemon hold amulet coin to double the money.
you keep on beating the Elite 4 and every time you beat the Elite 4 the the successful launches goes up one to two times i don't think there is a way.
