I sent out luxray first which caused her to switch to seaking. I predict the switch and send out noctowl to use hypnosis. I switch to cacturne to take out the seaking. I use cinderace with poison sweep to kill the primarina, but had to revive him once because he was the only mon that outsped. I used cacturne on the dewgong and HAD to hope for a crit. Luckily a crit one shot and it never attacked me after numerous turns. Luxray did the rest.
