>>50777131Level up Lapras till 32 when it gets Ice beam and buy some X Speed/Special from Goldenrod and maybe some healing items. Sleep/Para the Gyarados with Gloom and then switch into Lapras boost up with X Items and sweep the rest of her team. I'd also recommend evolving Gloom at this point, you can get the Leaf Stone from the Pokeathlon or the Sun Stone from the Bug catching contest.
