So i just battled this team and found some stuff.
Ninjask looks good overall. You're actually not going to use him to attack. I recommend this EV Spread: 248 HP/ 224 Def/ 36 Spd. Speed EVs don't need to be Maxed Out as he's going to outspeed the whole tier, even the majority of Scarfed Pokes. Also, give him an Impish Nature. He needs to stay on the battlefield as long as possible so you can get more and more and more Speed Boosts and more SD's. I actually prefer Protect over Substitute so that could work.
Furret's turn. This guy really surprised me. I really had no idea anybody would even use him. Once again, you are missing 4 EVs. I would recommend 4 HP. Also, i would replace Aqua Tail for ThunderPunch. Paired with Ice Punch, you will have the formidable BoltBeam combination. Only Magnemite will resist you (Who even uses a Magnemite in NU?!) and Shedinja won't take any damage from you. But Shedinja is rare as well so...
On to Eelektross now. So you're using Smogon's set. It's pretty good apart from the fact that i prefer Specs for the added power. Some people prefer Leftovers but that just my two cents.
Rampardos..... You're using an unusual set here. Outrage + Lum Berry was a combo i idolized when i was younger but in NU.....? Nah. Rampardos has many many more attacks he can benefit from. Sure, Outrage is powerful in NU as of the lack of Steel types but it's way better when STAB. I'll be suggesting a whole new set:
Rampardos (M) @ Choice Scarf
Trait: Mold Breaker
EVs: 20 HP / 252 Atk / 4 Def / 232 Spd
Jolly Nature (+Spd, -SAtk)
- Fire Punch
- Head Smash
- ThunderPunch/ Zen Headbutt
So my Smogon set variant. Fire Punch kisses bye bye to Grass types while Head Smash is terrifying STAB. Earthquake and Head Smash make the EdgeQuake combo. On the fourth moveslot, ThunderPunch can be used for Water types while Zen Headbutt crushes those Fighting types that resist Head Smash.
To Alomomola now. I suggest this set:
EVs: 252 HP / 252 Def / 4 SDef
Impish Nature (+Def, -SAtk)
- Knock Off
Credit to Mike for this set. Tired of typing xD Figure it out yourself.
On to Floatzel. He adds more Electric and Grass weaknesses to your team. He's also the 4th physical attacker of your team. An opponent with Alomomola or another physical wall such as Weezing could screw you up. I also found that he wasn't supporting your team whatsoever. That is, during our battle. I will be suggesting a good Special attacker:
Charizard (M) @ Choice Specs
EVs: 252 SAtk / 4 Def / 252 Spd
Timid Nature (+Spd,-Atk)
- Fire Blast
- Air Slash
- Hidden Power Grass
- Focus Blast
This guy hits so hard...... Specs boost his already-high Special Attack to insane levels. Fire Blast and Air Slash are STAB and hit hard while HP Grass and Focus Blast are coverage. 'Nuff said.
Sorry if this is a too short answer. I did my best, though. Hope i helped!
