Yay how do you use the wish stone and make a wish.i herd you should use..

Well actually when you turn down jirachi when it ask to join your team. It hears a song and lets you make a wish. If you select "Wish for something good" and you leave the cave, the next day a Pokemon will come to your house and ask to join you team.The only only Pokemon that ask to join your team are ones that you haven't recruited. So lets say the only Pokemon you had left to recruit was kecleon a kecleon would come to you house and ask to join. However all the Pokemon that do jone whilst using this method are all at level one.

You need to go to wish cave and reach b99 and got something speacial and you will get jirachi

It may be easier to wait until you have a Pokemon over level 90 and have a Friend Bow then just go "rob" one of the stores in a dungeon (run off without paying) to get a chance to recruit one of the many that will come after you, then use an Escape Orb to get out, but to get Kecleon by wishing would be tough unless you had almost all the other 386 as it could be any that one you don't have yet...or if you aren't at Lucario Rank, asking for "Something Good" can also increase your team's ranking.
The other wishes you can make:
"Lots of money"-all of the money from Wish Cave
"Lots of items"-all of the items in Wish Cave
"A Friend Area"-one of the Friend Areas you don't have yet
"More strength"-An item that will raise your stats
You can keep going back and wishing again until you recruit Jirachi, too, but that's up to you.

Wish stones can be used not just if you turn down jiratchi but if you accept him and leave him in his friend area then he will appear in wish cave again to use a wish stone but I'm not sure if it's true.....
