There are several side quests and occurences that you can also pursue during your quest for the legendary cards. Ishihara's House The Pokemon collector Ishihara's house is in the upper left part of the world map. You need to go there to find Grass Club Master Nikki initially, but he will also be a valuable trading partner. Over time, Ishihara will offer to trade his Surfing Pikachu Lv13 for your Clefable Lv34, his Flying Pikachu Lv12 for your Ditto Lv19, and his Surfing Pikachu Lv13 for your Chansey lv55. Check back with him often. Ishihara's library is also a great source of information about various Pokemon. Ronald Your rival will show up and challenge you from time to time. The first time will be after you win your second Medal. Ronald- I'm Ronald! deck Prizes: 6 Win: Jigglypuff Lv12 This deck is made up mostly of basic Pokemon, of various types. Whatever deck you used to win your second Medal should be plenty good enough to defeat it. Your second duel will come after you've won your fifth Medal. Ronald- Second Duel deck Prizes: 6 Win: Super Energy Retrieval This time, Ronald will play smarter and use better cards. I suggest using a Psychic or Fighting deck to duel with him, or maybe a combination of the two. He will use mostly powerful basic Pokemon that need no evolution like Hitmonchan Lv33 and Tauros Lv32. Ronald will challenge you again at the second Challenge Cup. Ronald- Third Duel deck Prizes: 6 Win: Jigglypuff Lv12 By now, Ronald has learned that you are someone to contend with and has pulled out all the stops to try to beat you. He will use several different types of Pokemon, so I suggest a Psychic deck with an energy removal strategy. If you win, you will get another Jigglypuff Lv12, the same as the one you won for beating him the first time. After this, you won't see Ronald until you enter the Pokemon Dome and challenge the legendary Masters. Challenge Cup Once or twice during your quest, at unknown times, a Challenge Cup will be held at the Challenge Hall. If you arrive at the right time you can enter, and will face 3 random members of the various Clubs in duels. if you win them all, you will have won the Cup, and will be given a very rare card as a reward. The first time you win, you will be given a Mewtwo Lv60 card. The second Cup you win will get you a Mew Lv8 card. Challenge Cups will continue to be held randomly even after you win the legendary cards, and will offer various very rare cards as prizes. Imakuni? A very strange man, Imakuni? is a mystery even to the other people in the Clubs. He claims to be a musician, but also wears black mouse ears on his head, so who knows for sure? He will appear randomly from time to time in a Club, and you can challenge him to a duel if you can find him. Imakuni? Prizes: 6 Win: One of each booster Imakuni? uses a Water/Psychic type deck. A decent Lightning or Psychic deck should be good enough to beat him, especially since he insists on playing his trademark card. The Imakuni? Trainer card is an interesting collectible, but all it does is Confuse your own active Pokemon. Imakuni? will use it all the time, and if you beat him enough times, he'll give you one of your very own!
