The team looks pretty fresh, but a lack of speed really pops out at me right now. I propose this solution.
Flygon @ Choice Scarf
Ability: Levitate
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Outrage
- Earthquake
- U-turn
- Defog
I really like scarfgon. I think it's extremely splashable, a great momentum grabber, and a very good revenge killer and cleaner. Anyway, I'm using it over scarf TTrum because the team, as it stands right now, is pretty weak to spike stack, which scarfgon can remove in a pinch and is generally a nice mon to use vs spike stack due to levitate and a favorable matchup vs garb, qwil, and accelgor. If Musharna gives us all the momentum we need, U-turn or Defog can be dropped for Aerial Ace to smack virizion, which the team is very, very weak to, even with musharna around. As much of a scarfgon as I am, I think that it's a very legitimate choice for the last slot of the team.
