these are the moves:
Rest and Sleep Talk (rest talker)
P.S this is a Thick Fat, leftovers Walrein
Why? This makes for a good staller and Encore can lock them into a status move and you can kill them with Surf while Ice Beam is a good offensive option with OK power and it gets STAB. Can be bought at the Game Corner in Mauville. Toxic makes for a good staller. I chose these moves to use because it provides good support and a Surfer if needed. I used this set so I recommended it. Worked extremely well for me. May not do anything to steel types, but Surf kills them slowly and Leftovers provides recovery as you do that.
Hope I helped!
