The biggest problem by far is that Sandslash is just...there. He exists in your party for most of the game without doing anything of note.
My Sandslash currently has 75 Sp. Defense at level 51 (and for reference 152 HP, 122 attack, 136 defense)
Do you have a special defense lowering nature? Mine has a neutral nature.
As for just being there I'd have to argue against that. I've been using mine a fair bit for hitting poisons, rocks, ghosts (I opted for Shadow Claw over Rock Slide; apparently Sandslash can outspeed most of the Jellies, who knew) and just general hitting of things. But that will probably vary based on people's team mates
