Trick Sand

[Bootortle]

I would like some help with this team, since the Regional in my area is in a couple days.

So, to start, I have:
Tyranitar @ Focus Sash
-Rock Slide
-Crunch
-Protect
-Superpower (any suggestions for a replacement here?)
Stats at level 50: [Adamant Nature]
HP-172
Attack-203
Defense-134
Sp. Attack-97
Sp. Defense-119
Speed-71
This guy is there to set up the sandstorm, and then hit hard. Protect is there for common reasons(Fake Out, Fighting type moves, etc.) Crunch is for a strong Dark STAB(Great for Cresselia/Latios), and Rock Slide is there for spread damage and Volcarona. I'm not sure what to say for Superpower, though. He can usually take hits pretty well, so that's a plus. His speed is excellent for Trick Room. Obviously, he is a strong physical attacker.

Gyro (Reuniclus) @ Life Orb
-Shadow Ball
-Psyshock
-Focus Blast
-Trick Room
Stats at level 50: [Calm nature]
HP-193
Attack-76
Defense-110
Sp. Attack-170
Sp. Defense-133
Speed-50
This guy is the big special attacker of the bunch, and is one of the two that can use Trick Room. Psyshock over Psychic, because I fell as if it is slightly more fitting. Shadow Ball is there to hit ghosts and other Psychics, and Focus Blast is a strong fighting type move (although it is risky at some points). He takes hits pretty well, too, but not as well as Tyranitar.

Boo (Dusclops)@ Eviolite
-Trick Room
-Night Shade
-Wil-O-Wisp
-Pain Split
Stats at level 50: [Bold Nature]
HP-115
Attack-84
Defense-191
Sp. Attack-77
Sp. Defense-177
Speed-40
Although total taunt bait, this guy is good. He can take any hit like it's nothing, and then Wil-O-Wisp right back. Night Shade is there for 50 damage all the time (and for Taunt)
and Trick Room is there for Trick Room (obviously). Pain Split can be useful if he has low HP and the opponent just switched in. Another plus, he's immune to Fake Out, so I can start a match only fearing Taunt. On to the next guy!

Dancer (Swampert) @ Sitrus Berry (any suggestions for a better item?)
-Waterfall
-Wide Guard
-Rock Slide
-Earthquake
Stats at level 50: [Adamant Nature]
HP-196
Attack-178
Defense-110
Sp. Attack-85
Sp. Defense-107
Speed-80
This guy is there for more strong physical power. He can be quite useful at times, and Wide guard protects him and his partner from common spread moves. Rock Slide is for Pokemon not affected by Earthquake, and Waterfall is a strong Water type Attack. His Earthquake works well with the next guy's Discharge.

Mr. Too (Rotom-Mow) @ White Herb
-Thunder
-Shadow Ball
-Discharge
-Leaf Storm
Stats at level 50: [Modest Nature]
HP-125
Attack-63
Defense-133
Sp. Attack-159
Sp. Defense-135
Speed-102
The lawnmower here is my second Special attacker, whose primary goal is to counter annoying water types I was having trouble with before (including his own Washer form).
Discharge is there for spread damage, and goes well with Swampert. Thunder is there to counter rain teams. Shadow Ball hurts psychics. And Leaf Storm is used with White Herb so he can launch off 2 strong STAB Grass Attacks against anything that needs to be put down (Other Tyranitar, Gastrodon, Rotom-W, etc.) Also, his name is an anagram.

Finally, we have:
Peek (Omastar) @ Air Ballon (this isn't the best item for doubles, replacement suggestions?)
-Earth Power
-Ice Beam
-Protect
-Surf (should I replace this with Hydro Pump?)
Stats at level 50: [Gentle Nature]
HP-139
Attack-68
Defense-125
Special Attack-163
Sp. Defense-92
Speed-105
This is the only female on the team, and really useful against Rain teams due to Swift Swim. In Sandstorm, her Sp. Defense is boosted, so she likes either weather. She is one of the best Garchomp counters, with that speedy Ice Beam and ignoring ground attacks. Ice attacks are very useful, but this is the only Pokemon on my team that uses one effectively. Earth Power is a strong Special ground move, Surf (Hydro Pump?) is a strong special water move, and Protect is for the same reasons as most with Protect.

Some common threats to the team include Scizor, since I can't hit one for super-effective damage. Latios, because he's always a threat. Taunt users if there isn't rain. And many unmentioned as well.

If you would like to see them in action, here's the battle video number:
26-72323-27168

So, what do you think?

 

[Hydro Cannon]

Definitely watch out for Thundurus w/taunt and grass knot. Rain teams will also prove to be a little challenge, and Scizor just loves your team. Still looks kind of solid, I wish you luck at Regionals.

 

[Bootortle]

Thundurus doesn't take a Rock Slide too well, and Scizor loves my team, but can usually be taken down with a couple of Rock Slides, or Focus Blasts, or Thuders/Discharges. Mr. Too and Peek both like rain and Boo and Gyro don't mind it.

 

[One Approved]

Can you post the EVs for each pokemon instead of the stats for each individual one? It looks like you EV trained them (203 Attack on Tyranitar doesn't just happen on accident,) so it would be easier for you to just post the EVs instead.

Anyways, I like your movesets on the first two Pokémon. The only suggestion I would have is to try and make Reuniclus a + Special Attack nature instead of a + SpDef one, so it will hit much harder. Quiet would be preferred, but Modest works as well.

Dusclops, I would honestly just scrap. It really is a terrible pokemon. I know 130/130 defenses with Eviolite looks really good, but it's just not powerful enough to take multiple hits from the opposing team. I think Dusknoir would work much better. It has Trick Room, good defenses, but it also has a usable Attack stat, which can be very helpful. Otherwise, Cresselia, Uxie, Bronzong, and Metagross are able to use Trick Room very well. Metagross can hit hard, while the other 3 play more supporting roles with Helping Hand, Reflect, or Light Screen.

I'll be back after I work to rate the last 3 Pokémon.

Thank you for the input, but I'm not sure what I would replace Dusclops with. I like him because he's so bulky (And I like his design way better than Dusknoir). The replacemet options I like best are Porygon2 (who is also bulky, but can actually attack) or Chandleure(This one has a lot it could do). Both of the alternatives have more than four useable moves, so that would be helpful. I'm not sure which would be more useful, though. I may be able to post EV spreads, if you would give me a while. And, is there any way to change natures?
