Honestly, I just use a z fleur cannon Magearna. If the opponent has no steel type, then I just lead with Magearna and click on the z. Pelipper should be afraid of a thunderbolt or volt switch and would thus switch to Swampert, which gets destroyed by z fleur cannon. If Pelipper doesn't switch out then it's the one that will die to the z fleur cannon so whether the other guy switches or not, I win. This does get a lot more complicated if there is a steel type though
