it was to be creative. like the other moveset that was creative but hard 2 use. I thought it also might be helpful in certain situations. ie: if u need a staller pokemon/ want to stop a bper, etc. the point is, it is a very guaranteed switch, u just need some luck. and if alakasm can survive 1 psycial attack with all evs into hp and def, and def + nature, then u can give it pyschic, which basically means, u cause a switch use psychic to get a free hit in. and if i remember correctly alakasm has strong sp. attack, so as long as alakasm can use a good sp attack, it will do good to give a surprising attack.
