Cheater!! Cheater!!

• Whenever Dr. Mason e-mails you a booster pack, save your game before opening
  the e-mail. Once opened, if you do not want the cards in the booster pack,
  shut the game off immediately and start over. This time, the cards in the
  booster will be different. Repeat until you find the cards you want.

Patience is for Panzies!

• If you want to give all of your cards to the man in order to get your MP
  Pikachu a faster way to do this instead of waiting for him to ask for one is
  to do this: When he asks you for a card give it to him, write in the diary,
  and shut off the gameboy. Turn it back on and talk to the same man. He will
  ask for it immediatley. Repeat in order to get the MP Pikachu way faster!
  

The game auto-saves in a battle... abuse it!

• Tip 1
  First you must understand how the game saves. The game automatically saves
  after each input command that you do. It does not save after your opponent
  attacks, only after you input. Use this to your advantage. If you get a
  result you don't like, just turn off the game, then turn it back on. Now you
  can try something else.
  

• Tip 2
  See all of your prizes
  After you beat an opponent, select a prize. Once you see what it is do Tip 1.
  When you turn it back on you will be back to just before the attack. Attack
  again and select a different prize. Repeat this with all prizes and you can
  select the one you want/need.
  

• Beat the coin flip
  Coin flips in the game are NOT random. They are on some type of predetermined
  routine that you can take advantage of. If you have a Pokemon that has a
  damage attack and a coin flip attack (like Lapras) then always try the status
  attack first. For example, if you have 2 Water energies on Lapras. You can do
  a 20 pt Water Gun or a 10 Confuse Ray attack. Try the Confuse Ray attack. If
  it's heads then you get the 10 pts damage and your opponent is confused. If
  you get tails, simply turn off the game as soon as the coin shows tails and
  start it again. Now do Water Gun. Don't bother with Confuse Ray because once
  it's tails it will ALWAYS be tails. This can also be used with trainer cards.
  Once you know what the coin flip will be you can decide if you want to use
  cards like Gambler or Recycle.
  

• Psychic Killer
  The Meowth lv14 card is the ultimate in Psychic killers. Simply put him out
  when your opponent has alot of Psy Pokemon and he'll take out the benched
  characters. His Resistance keeps him safe and having some Potions and
  Defenders assures you an easy win. Four of this cards should be in your deck
  when you expect to face Psy decks.
  

• Challenge Hall
  Save the game before each battle. Now enter the battle and see what type of
  deck your opponent is using, Use the almighty Tip 1 to go back to before the
  battle and when you're asked if you want to prepare your deck, just say yes
  and choose a deck that is the stronger one. I suggest carrying a Fire Deck,
  Water Deck, Electric Deck, and Grass or Colorless deck. No one is resistant
  to Fire (and Ponyta and Magmar give you 30pts for 2 energy attacks); A decent
  raindance deck can beat any Fire deck in the game; The sheer amount of
  Pikachu cards (and you can use 4 Pikachus AND 4 Pikachu variants like
  Surfing) gives good access to the killer Raichu card and most can Paralyze;
  and smart use of the "Team Rocket" cards Koffing/Weezing & Ekans/Arbok can
  destroy anything short of a straight Fire deck.
  

• Best Pokemon
  Scyther is clearly the best non-promo giving a 60 pt attack by turn two
  (killing any Pokemon with Grass Weakness). Using a Scyther/Rattata/Spearow
  combination gives three zero retreat cost pokemon that cover loads of
  different opponents. Simply swap them whenever it's best for you (especially
  when poisoned).
  
  

• To get more Legendary Cards, beat the Grand Masters again, and 1 randomly
  selected legendary card will be added to your collection. When I beat the four
  Grand Masters and I had 2 of every card, they said that there wasn’t any more 
  to give so don’t expect to get a lot of those.

Promo Plethora!  

• Here is a very cool cheat.  After you have beat the Elite Four and
  Ronald it will make the game randomly open the Challenge Cup more
  often.  Also you can win any of the promo cards for prizes.  Well here
  is the cheat.  Always save before each of the 3 matches.  If the card
  you get is not the one you want restart your GameBoy and start from the
  save game before the last match the cards will be different.  I tried
  this and it does work it got me my Lvl. 9 Slowpoke to give me all 226
  cards!!!
  

Imakuni?

• This is relatively easy to do. First go to each club lounge until you find
  Imakuni? Then battle him which isn’t hard to do and you’ll get 4 Booster Packs each
  time. However he may give you his Imakuni? card. Repeat the process until you have
  most of the cards you need to build a healthy deck.

Don't let the Fat Lady sing too soon!

• One tip is when you beat the grand masters go to the deck machine on the top 
  of the screen before you get the cards to build an awesome deck. If you don't it
  will go to the credits and you will have to beat it again

Fire Club Trade?

• I know a way to get the Lv.9 promo Slowpoke easier. You can put all of your
  energies except one in temporary decks. Then talk to the boy. He will
  reveal the location for only 1 energy!
