Hint: Better card pop card with your rival
Save the game before you card pop with your rival. If you do
not like the card, turn off the Game Boy Color and try again.
Repeat this as many times as needed.
Hint: Cards for cards
When you get to the Pikachu Gambling Center on Great Rocket Island,
go to the big machine. For five tokens you can send five cards to
Dr. O-Yama. If he likes them, he may get good cards for mail.
