Hi, suggestions are always welcome !
But I have no reason to use Clampearl/Gorrebys/Huntail over Cloyster.
If I wanted to use anything over Cloyster it would be something that 1HKO's Slowbro/Slowking or has access to Taunt.
As much as I'd love to play Battle Subway and stuff, stuff relating to the VGC has been taking up a lot of my time for playing Pokemon. You could say that I'm taking a long break.
