>>16167494I'll go through each pokemon just for you bud. I'm being as critical as I can and my criticisms are going to be based 100% on the current meta + team synergy.
Ferrothorn - I'd drop the rocky helmet for a leftovers instead. I know 90% that you're using rocky helmet instead of leftovers because there's only 1 in the game. Train 6 lvl91 dedennes with pick up from restaurant le wow. I have 17 leftovers already. I would drop power whip and give it stealth rock so you can open up a move slot for your garchomp. Your chandelure already has energy ball. Reason why any team should have a grass type move is for the water/ground master race dual types and it doesn't matter if the grass type move you have on your team is physical or special when it does 4x damage.
garchomp - Since you would have an open slot because ferrothorn has stealth rock, I would give your chomp swords dance or dragon dance (preferrably swords dance since you are already jolly). I don't like the small % chance to miss with dual chop but I do understand why you have it (substitute)
Starmie - Went over already. If I had to pick a replacement, I would go for a tentacruel with rapid spin, scald, recover, toxic. Can rapid spin and can bait an earthquake so you can switch in your talon flame stealth rock free
Talon Flame - Can't really say anything here. It's a general standard build. If you want, you can get a flying gem and use acrobatics instead but its all personal preference.
Chandelure - Same as Talonflame. It's a standard scarf build. I would get flamethrower instead of fire blast only because I hate those small miss chances but it's again, personal preference. If you really needed that extra power with a fire type move, you already have overheat.
Sableye - I guess this is your unique snowflake pokemon. If you want a pokemon that does what this guy does but better, I would get a duskclops with an eviolite and give the leftovers to your ferrothorn.
