Er, I don't think much people here will approve of hacking, but to answer your question, you can Google online Pokesav.
I personally don't got a problem with people using Pokesav Pokemon, as long as they aren't given impossibly high stats (31 IV's everwhere), attacks that cannot be learned, and made automatically shiny.
However, people who only have Pokesav Pokemon are really missing out on the satisfaction of raising a Pokemon!
(Unless the Pokemon they made is at a low level)
