@ Texas: i do agree with dark-ray: It is my understanding that you should use the 3, and can only use pokemon that you cannot encounter until beating Fantima.
Ex: if i used that challenge in Heart Gold and I got a 3, I can only use pokemon i could find after beating Whitney but before Morty (eg. Miltank, Tauros, Magnemite, Flaffy, Farfetch'd, Mankey, etc.) (Sadly 4-5 are all the same (Safari Zone doesnt open until I beat Jasmine if I recall).
His challenge was for new pokemon that you can access between beating the gym you roll'd (Fatima) and the next one (Maylene).
