Here’s your team, but fixed:
Orangoru @ Mental Herb
Ability: Inner Focus
Relaxed Nature
EVs: 252 HP/140 Def/20 SpA/92 SpA
IVs: 0 Spe & 0 Atk
- Trick Room
- Psychic
- Instruct
- Protect
Description: Telepathy is completely useless as you don’t have any moves on your team that hit all pokemon, so Inner Focus is much better as it allows Orangoru to not be shut down by Fake Out. 0 Speed IVs is to ensure outspending (or underspeeding, depending on the way you look at it) your opponent. 0 Attack IVs is to minimize confusion damage. Safeguard doesn’t help much, so I put Psychic on instead to perhaps finish off an opponent at low HP.
Shuckle @ Life Orb
Ability: Sturdy
Brave Nature
EVs: 252 Atk/172 SpD/84 HP
IVs: 0 Spe
- Power Trick
- Rock Slide/Stone Edge
- Knock Off
- Gyro Ball
Description: I think Rock Slide would be more practical than Stone Edge as it has better accuracy and hits both opponents, but I guess with instruct it doesn’t really matter. Z-Power Trick doesn’t offer much niche, and the Z Move slot is much better used on Stakataka.
Stakataka @ Rockium Z
Ability: Beast Boost
Lonely Nature
EVs: 252 Atk/252 HP/4 SpD
IVs: 0 Spe & 15 Def
- Trick Room
- Gyro Ball
- Rock Slide
- Protect
Description: Stakataka needs 15 Defense IVs in order to gain an attack raise from Beast Boost. 10 Defense IVs are much too little, 15 and Lonely Nature is the perfect combo.
Amoongus @ Sitrus Berry
Ability: Regenerator
Relaxed Nature
EVs: 240 HP/172 Def/96 SpD
IVs: 0 Spe & Atk
- Spore
- Rage Powder
- Giga Drain
- Clear Smog
Description: Much less gimmicky than your Toxapex and offers a huge niche in Rage Powder, allowing a partner to sweep, even without Trick Room.
Cresselia @ Leftovers
Ability: Levitate
Relaxed Nature
EVs: 252 HP/252 Def/4 SpD
IVs: 0 Spe & 0 Atk
- Trick Room
- Skill Swap
- Ice Beam
- Psychic
Description: Offers a great niche in Skill Swap, great Trick Room setter, has excellent bulk, and offers a nice support role. Stealth Rock isn’t very useful in Doubles, and your Palossand just didn’t add very much to your team, so I replaced it with him Cresselia.
Mawile-Mega @ Mawilite
Ability: Intimidate—>Huge Power
Brave Nature
EVs: 252 HP/252 Atk/4 SpD
IVs: 0 Spe
- Iron Head
- Sucker Punch
- Play Rough
- Protect
Description: Outclasses Camarupt-Mega by far as a Mega Trick Room sweeper. With a much better offensive typing, better ability, no 4x weakness, and ability to hold its own without Trick Room (with Sucker Punch) makes it a much better choice over Camarupt-Mega
That’s it! Sorry I replaced half of your team, but I truly think this’ll is the best way to maximize your team’s potential. Good luck in your doubles adventures.
