I'm am pretty sure this has been asked before but I couldn't find it. So, for some clarification. Basically, what stats of the opponent does it copy? I've heard that for hackmons on showdown, imposter blissey is a good idea. So, I assume that imposter does not copy the hp. But I also know that imposter does copy speed, because in showdown when my ditto copies something it gives the estimated speed of the opponent. So, which stats does it copy?
