mew, they might have equal stats, but mew can learn every single TM, and it can even transform into jirachi, so, well, there really isn't any possible doubt :s
Can you guys stop making pointless thread like'Mew vs Jirachi' or 'Mewtwo vs Deoxys'.I think it is considered postcount. If you really want to do it just play in the game corner.
They are questions for people, the person who made it probably want to know who is better, like me when i made my "Mewtwo VS Deoxys" thread, i wanted to know who is better in strength, and other things i wanted.
