Before I type anything, I just want you to know these sets and Pokemon are just my opinion. I'm not trying to edit your team for you or tell to change anything. These are just ones "I think" could help.
How about a
Brave Escavilier? +ATK - SPD
Only issue is, if their packing a fire type move. They'd 1hko your Foretress along with this.
neutral as for moves,
X scissor - STAB damage
Iron head - STAB damage
No idea on the other two moves, maybe Swords dance and Giga Impact?
or Toxic and Protect?
Also How about a
Quiet Elektross? - SPD + SPC ATK
half of your current team is weak to Earthquake a VERY common move. Switch to this lil fella and take advantage of its Levitate ability.
as for moves,
Volt switch
Flamethrower
Flash cannon
thunderbolt/thunder/protect if you happen to use toxic on another Pokemon to help drain their health.
How about a
Brave Rampardos? +ATK - SPD
This bad boy packs a whopping 471 ATK give em some trick room and it's clobbering time.
as for moves,
Head smash/Rock slide/Smack down/stone edge - STAB damage
Earthquake
Thunderpunch - rid of those water types trying to take out your fire.
Giga Impact/swords dance/hammer arm or rock polish - when your trick room ends, you can boost your speed drastically with rock polish.
Lots of options, these are just 3 I think would help with a trick room team.
Edit: adding 1 more.
Timid Espeon +SPD - ATK
Reason being, you only have 1 Pokemon with Trick room, and once its all gone you'll need a speedy Pokemon to set it up again. Just in case your Chandelure gets 1hko after setting it up. You have this speedy Espeon who can not only set up another Trick room, but also lay the smack down or lay down a defense if necessary.
as for moves,
Trick room
Psychic - STAB damage
Shadow Ball/Toxic/Reflect/Hyper beam/Hidden Power
Morning sun/Protect/Light screen/Signal beam - so you can beat down those Dark types.
Edit 2: Adding another one, I bet your tired of me by now LOL
Timid Gengar. +SPD - ATK
May be a better choice than Espeon, due to having a better move pool. not to mention Gengar also have the ability Levitate and is a Ghost type..so some moves wont effect you. =)
as for moves,
Trick room
Shadow ball - STAB damage
Thunderbolt/Toxic/Will-o-wisp
Focus Blast/protect/Confuse ray
As for your Infernape, Maybe switch out Brick Break with U-turn. Unless you have the Brick break to knock down Reflects and Light screens.
Just a suggestion. -shrug-
Also why Naive Nature? Try to get a Jolly Nature Infernape. Naive + SPD and - SPC DEF. Thats going to hurt you in the long run.
neutral Heres a website that shows the natures with their boosts and such.
http://www.legendarypokemon.net/natures/ Was looking at your Chandelure, it's speed is quite low. It may not be able to set up the trick room in time. Maybe breed another and get a Quiet one which is +SPC ATK - SPD so it can be part of the trick room team. Even if it was a +SPD nature, the most it could be is 284. Alot of Pokemon in competitive play are over that. It's just a suggestion, if you like it the way you have it. Then leave it be. =) Just hope you dont get 1hko'd before you can set up the trick room, then your strategy will be useless. =(
I think I'm done for now...anyhow if you like any of these feel free to use them, if not I tried lol. Hope I helped.
