it is simple first u must have got up to the point were u r able to go to the newly built collosseum,(were u got the gear frm) beat all the leaders and when the game ends u will be warned about team snagem and two people with a shadow crowdant and quilava train them to lv 35 each and they will their evolved forms

AFTER YOU BEAT THE GAME THAT NED GUY SHOULD SEND YOU SOME EMAILS ABOUT A SHADOW QUILAVA....CROCONAW....BAYLEEF- THE OTHER TWO THAT YOU DIDNT CHOOSE IN BEGINNING.THE OTHER 2 POKEMON ARE LOCATED @ THE SNAGEM HIDEOUT CATCH QUILAVA @ LVL 30 THEN TRAIN TO LVL 36 THEN HE EVOLVES.

I think you have to go to pheanec city. After the battle in the mayor's house you see guys in different colors if you talk to the guy inthe red suit you will battle and see a quilava. catch it and purify it make it evolve and you've got a typhlosion!

early in the game you will battle a shadow quliva snag it then train it to lv.36 then your typlosion

in the begining of the game at phenac city when you go there the 2nd time snag quilava from mystery troop rosso the red guy he has quilava then one to his purifying stage and are past the agate village level purify and then at level 36 he will evolve into typhlosion and there you have it.

Typhosilon isnt a shadow pokemon you are porbably thinkin bout Tyranitar bcos that is the
strongest shadow pokemon in the game so you have to use a master ball on Tryanitar

P.S REMEMBER THERE IS NO TYPHOSILON (SOZ BOUT SPELLING) IN THE GAME

u will first get qualava then beat the pyrite and the agate village place go to mount
battle defeat 9 people and u face #10 which he has a shadow entie beat him go to agate
village to the cave oh yeah a person will give you the time flute u must of purified 2 or3
pokemon
now play the flute and celibi comes purify the pokemon u choose

first get the exp share then get every pokemon out by swaping them around then kill the
trainer with the pokemon with exp share and you will level all your pokemon every battle
