@tauvhieq this isnt even the right post for it...
anyways, to answer your question, the ralts was moved waaay later in the game (post aya AKA 5th gym leader) (to op plz nerf/move/axe) to the underground railnet, in one of the rocksmashable rooms. either way espurr/ meowstic is still great in the early game btw. just because you dont have these powerful mons early on doesn't mean that your gonna fail, come up with strageties!
hope this helps
