After November Regionals ended, I pretty much put away my DS and didn't work on my team or make any new ones until now. I took my regionals team and changed it around a bit to get the team I have now, or this team. So yeah, I'm just looking for suggestions on what I could do to improve this team before Regionals in April. Thanks in advance for any suggestions :)
The Team at a Glance:






---------------------------------------------------------------------
The Team

Hariyama @ Flame Orb
Nature: Brave
Ability: Guts
EVs: 248 Atk, 124 Def, 132 SpD
IVs: 31/31/31/30/31/0
Moveset:
-Fake Out
-Close Combat
-Ice Punch
-Protect
Hariyama is my typical lead to use Fake Out alongside Trick Room to get a guaranteed TR up T1. Close Combat hits like a truck after STAB and a Guts boost, and Ice Punch provides awesome coverage and OHKOs plenty of things weak to it. Protect is there in case I don't lead with Hariyama and need to activate Flame Orb.

Musharna @ Mental Herb
Nature: Sassy
Ability: Telepathy
EVs: 248 HP, 124 Def, 132 SpD
IVs: 31/30/31/31/31/0
Moveset:
-Trick Room
-Psychic
-Protect
-Helping Hand
Musharna is my standard TR lead to use with Hariyama. Since being taunted wrecks Musharna, I've given it a Mental Herb so that it can at least make it through the first turn and set up TR. Helping Hand is there to boost my ally's attack power, Psychic so that I can do damage if necessary, and Protect so I can live an extra turn.

Dusclops @ Eviolite
Nature: Sassy
Ability: Pressure
EVs: 8 HP, 248 Def, 248 SpD
IVs: 31/31/31/30/31/0
Moveset:
-Pain Split
-Will-O-Wisp
-Night Shade
-Trick Room
Eviolite Dusclops is one of my favorite Pokemon on this team. With Eviolite any attack hardly puts a dent in it while it can cripple you with Burn, heal itself and damage you with Pain Split, and damage you with a consistent 50 damage with Night Shade. It's also my back up Trick Roomer in case Musharna's KOed and TR wears off.

Suicune @ Lum Berry
Nature: Relaxed
Ability: Pressure
EVs: 248 HP, 8 Def, 248 SpD
IVs: 18/20/29/19/17/3
Moveset:
-Scald
-Rest
-Toxic
-Calm Mind
This was the Pokemon that inspired me to make this team. After getting what looked like a really crappy Suicune from the Gamestop event (I got it quickly and didn't check anything until I'd left the store... :/) I looked at it's low speed IV and nature and decided to try using it in Trick Room. Scald hits pretty hard after stacking a few Calm Minds, and while your opponent is wasting away from Toxic your healing off everything they did to you with Rest + Lum Berry.

Ferrothorn @ Leftovers
Nature: Relaxed
Ability: Iron Barbs
EVs: 248 HP, 148 Def, 108 SpD
IVs: 31/31/31/30/31/0
Moveset:
-Power Whip
-Leach Seed
-Gyro Ball
-Protect
Ferrothorn is amazing. Leach Seed + Protect is just so broken, just hit your opponent with a Leach Seed on each Pokemon then alternate Protect and Power Whip/Gyro Ball FTW. STAB Power Whip OHKOs a lot of things like Swampert, Quagsire, and Gastrodon and 2HKOs almost anything weak to it, making Ferrothorn one of the perfect counters to Rain Teams with it's resistance to Water as well. Gyro Ball doesn't have that great of coverage, but it's still alternate STAB and can hit Ice types such as Abomasnow harder than Power Whip.

Gastrodon @ Rindo Berry
Nature: Relaxed
Ability: Storm Drain
EVs: 248 HP, 248 Def, 8 SpD
IVs: 31/30/31/31/31/0
Moveset:
-Surf
-Earth Power
-Ice Beam
-Protect
Gastrodon is the final Pokemon on the team. With pretty good defenses, awesome coverage, the ability to absorb Water Spouts and Surfs, and low speed, Gastrodon is an awesome Pokemon and works well in Trick Room. When paired with Musharna, I can STAB Surf all day without Musharna getting a single scratch thanks to Telepathy. Earth Power and Ice Beam provide great coverage together and both hit pretty hard.
