A couple weeks ago, i was playing this guy on wi-fi on my platinum game, and one of the pokemon he used was a blissey (we were using all level 100s) and it used seismic toss over and over again. took out 3 of my pokemon i think. my question is this: how is it possible to teach seismic toss to a blissey? i looked on serebii.net for info in the pokedex section, as well as the attackdex section, but i have not found any viable non-hacking method of doing this.
