I will help with this if I can.
Ferrothorn:
Replace it for Forretress. That way you can have Rapid Spin. Use this:
Forretress@Leftovers/Rocky Helmet
EV's: 252 HP, 128 SpDef, 128 Def
IV's: 0 Spd
Trait: Sturdy
Relaxed/Sassy Nature
-Rapid Spin
-Volt Switch
-Stealth Rock
-Gyro Ball
Aegislash:
Put Leftovers here. Change the EV's for 252 HP/120 Def/120 SpDef/16 Atk. I recommend 0 Spd IV's, Brave Nature, and Shadow Claw in place of Shadow Sneak so that he can be hit in Shield Forme and hit in Blade Forme.
Greninja:
Switch the 4 HP EV's into Attack for U-Turn.
Rotom-H:
You want to replace? I have a couple great Fire-type candidates and an Electric one. This will take a while, so get ready!
Infernape@ Life Orb
EV's: 252 SpAtk, 252 Spd, 4 HP
Trait: Blaze
Timid Nature
-Nasty Plot
-Vacuum Wave/Focus Blast
-Flamethrower/Overheat/Fire Blast
-Grass Knot
Infernape is great specially. Nasty Plot and Life Orb combined with Nape's 104 Special Attack stat make for a great hitter. There is the choice of using U-Turn in place of Grass Knot and putting the 4 EV's into attack while changing the nature to Hasty or Naive. For a physical set, try:
Infernape@ Life Orb
EV's: 252 Atk, 252 Spd, 4 HP
Trait: Blaze
Adamant Nature
-Swords Dance
-Blaze Kick/Flare Blitz
-Close Combat/Mach Punch
-Flame Charge/U-Turn/Earthquake
Infernape's physical side is just as good as his special side. There is the option of Choice Band and replace Swords Dance with one of EQ or U-Turn. Flame Charge is a no for that because it would be used once- usually on a switch- to boost your speed. I don't think you should use it unless you go for Close Combat, as priority+ speed boosting is redundant. Or, there's a great mixed set:
Infernape@ Assault Vest
EV's:252 Spd, 128 Atk, 128 SpAtk
Trait: Blaze
Hasty/Naive Nature
-Close Combat/Mach Punch
-Flamethrower/Fire Blast/Overheat
-Grass Knot
-Any physical attacking move
One of Infernape's great assets is his versatility. This is probably Nape's best set because it destroys SkarmBliss completely with your Fire move of choice and Close Combat or Mach Punch. for "Any physical attacking move" I recommend using Flame Charge, Earthquake, U-Turn, Shadow Claw, Ice Punch, ThunderPunch, Poison Jab, Aerial Ace, or Stone Edge. Can you see why I didn't put that on that line? But I'm not done yet! For a special sweeper, this oughta work:
Volcarona@ Lum Berry
EV's: 252 SpAtk, 128 Spd, 128 SpDef
Trait: Swarm
Modest/Timid/Calm Nature
-Fiery Dance/Fire Blast/ Flamethrower
-Quiver Dance
-Bug Buzz
-Hidden Power {WHATEVER}
Volcarona is a really great Pokémon to use. You will need Rapid Spin support, however. Set is self-explanatory, I'm getting tired of this by now. Last set!
Jolteon@ Air Balloon
EV's: 252 Spd, 252 SpAtk, 4 HP
Trait: Volt Absorb
Timid Nature
-Thunderbolt
-Volt Switch
-Signal Beam
-Hidden Power {ICE}
Self-explanatory. Your Electric option here.
Gliscor:
Replace 4 Spd for 4 Atk.
Talonflame:
Plates are useless competitively outside of Arceus. Use Life Orb because it'll boost his attacks for no extra recoil. Swap the HP and Speed EV's.
I hope I helped!
