Serperior-Pure Power Type
-Leaf Storm

Serperior-Balanced Type
-Hidden Power [Fire/Ice]
-Aerial Ace
-Leaf Blade
-You choose if you need an other grass move or if you want something else.
Excadrill
-Rock Slide
-Earthquake
-X-Scissor
-Sandstorm/Shadow Claw/Posion Jab/Focus Blast <----You can switch between them after where you are since all of them are TM moves.
Sawsbuck
-Jump Kick
-Horn Leech
-Aromatherapy
-Nature Power/Shadow Ball
Hope this helped to give you a idea of how you're movepool should be.
