Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I'd try a SpA build with Dragapult
Dragapult @ Choice Scarf
Ability: Infiltrator
EVs: 252 SpA / 4 SpD / 252 Spe
Timid/Modest Nature
- Draco Meteor
- U-turn
- Fire Blast/Flamethrower
- Shadowball
as you can now keep Ferrothorn in check
That's a pretty nice team, but there is an important flaw;
>Sablenite on Sableye
>Bold > Impish, cuz u're using Shadow Ball (which could be replaced with Dark Pulse due to the normal spam / fight spam)
Nice team as always, keep up the good work!
Dugtrio: You should replace Substitute with Stone Edge for OHKOing Zard Y and Talonflame
Sableye: Impish > Bold cuz you're using Knock off and Fake Out
