Since Yours Is EV Trained In Attack, I Will Give A Physical Moveset. If You Would Also Like The Special Moveset, Comment Below, and Ill Edit it.
Physical: Item: Quick Claw:
Rock Slide: It Covers So Many Weaknesses, that Just Like Sceptile, It Is Worth It.
Power Whip/Seed Bomb: STAB, Decent Coverage.
Sleep Powder Isnt Exactly Accurate, But If You Want To Keep It Go Ahead. If Not, I Would Suggest Earthquake To Cover Its Final Weakness.
Finally: Leech Seed: For Healing, Or Brick Break or Poison Jab For More Coverage.
Mine As Well Make Use Of That Chloyaphyl, or Leaf Guard.
Sunny Day: Ability, Solarbeam, Etc.
Solarbeam: STAB Strong Acc. and Power
Ancientpower: Covers 4 Weaknesses
Synthesis: Heals Alot Of HP In The Sun:)
Preferably Holding A Heat Rock.
