Chain of Memories White mushroom cards

Has anyone gotten one of these, I've spent the last couple of days trying to get one. I'd like to know if there is some sort of trick or something besides just satisfying them that I have to do. It is now the last card I need before I get 100 percent.

 

i remember getting it in Twilight Town is the original, but im not sure about RE: CoM

 

Well,i don't think that there is a trick about getting it...But i remember trying A LOT to get that one!:/ I'm sorry for ya man...

 

you only have to fight and hoping
they give you a price if you use the magics on them (like KH 1) and they'll give you that yellow card with the P between (if you have it at the end of the fight, you can choose a card from your deck and then it'll use less CP)

 

you have to keep fighting them and giving them the element they want and hopefully they'll drop it.
