You know, you can buy coins!!!!!!!!!!! You could just buy 9,999 coins if you have enogh money. The coins are 50 for $1,000 or 500 for $10,000(yes, they are kind of a rip off but this way is still easier than trying to win the coin game!). If you need money, get the amulet coin(it doubles the money people pay you when you beat them) and give it to a pokemon that you use a lot against the Elite Four. Then go fight the Elite 4 many times until you have enough money.
