Go to the event.There is no way around it.
Trade with someone that did the events. That's about the only way.
you can get to all islands without events to get the three remaining legendaries are paticipating in an event not possible anymore or action replay, cheating and glitching with the game.
i think you have to trade them from other games
I think it's impossible without cheating, you can get almost all Pokemon the normal way, but pokemons like celebi, jirachi... i don't think it's possible without cheating... sorry
no, arceus is an event Pokemon. all event Pokemon are impossible to encounter without an action rep;ay
trade from other games
Yes you can, with hard work and dedication.
No i can,t because i don,t have Action Replay and its not time for the arceus event I just want it in My pokedex that all i want how do i do it
Don't cheat then. The only ways to get Mew is to go to a Nintendo Event or use a cheating device. Unless if you have Pokemon Yellow/Red/Blue, there is a way to catch Mew without cheating.
It is only cheating if the 386 Pokemon were acquired by a hacking device such as action replay/game shark , but it does sound rather suspicious because its very , very hard to get all 386 Pokemon without cheating.
Not possible unless you use a cheating device.
You cannot without a cheating device such as the Action Replay. Sorry.
