Catch it.
Nope, unfortunately there has been no legit way to catch celibi in the mainstream Pokemon games (ruby/fire red/platinum etc)
Stop cheating and catch your pokemon legit
At this time, there is no legit way to capture him.
I've tried to do what it says on u tubebut it didn't workModified by Wyra: There is no legit way to steal a rental Pokemon from the Battle Tent -- "legit" including glitches.
NO it isn't legit if you cheat to get it.
Trade from Ruby and Sapphire is a must, how ever jirachi and deoxys can't be obtained without going to events but the u.s.a no longer holds gameboy advance events, however it is possible to obtain every other Pokemon legit
You cannot get Mew legit in Pokemon FireRed, for the event for Mew has ended. You would need to use a GameShark or trade for it from Pokemon Emerald.
legit means not hacked.
in Pokemon pearl or diamond, you cannot find a legit deoxys. you can only get one in Pokemon emerald, firered, leaf green by visiting birth island.
You can only Catchall Pokemon in Emerald using a Hacked Rom OR Patching OR Cheating with Codes such as Gameshark & Codebreaker & Action Replay. For those who like legit ways you cant catch but you can get all Pokemon by trading from others using two Gameboy Advance with Cartridges or use VisualBoyAdvaceLink (its an Emulator for Playing GB/GBC/GBA roms on PC) its Better option in my opinion.For Trading you can get save files from various websites or Simply use your savegames in Both Windows. Search on Google for link to VBA Link's Homepage. 1.8.0 beta3 was latest version when I Checked it Last. Hope this Helps !!!!!
No, besides getting it from a honey tree, trade is the only other legit way without cheating.
