I Found this one Great: Ice beam: Drake. Grass. Surf: STAB Earthquake: Duh. Brick Break/Mud SHot/Rock SLide: Rock Slide is Move Tutor, but a good move. Mud SHot Lowers Speed Nicely. Or Brick Break For Move Coverage against The Elite 4.
I think it would be: mud slap hydro pump earthquake and probably surf
Well this is a moveset that I have tried and it worked pretty well for me:
Earthquake Blizzard Surf/Muddy Water/Hydro Cannon Hyper beam
