Sitting at home one day, I decided to make a trick room team for UU play. Looking through the pokemon with very low base speed, I stumbled upon Trapinch. With a base 10 speed and base 100 attack, I realized that it could "outrun" anything in trick room, and could use arena trap to prevent the opponent from switching to a counter. And so the team was born.
Changes to the team are in Italic.
Uxie @ Leftovers
Levitate
Careful
252 HP/160 Def/96 Sp Def
Yawn
Trick Room
Stealth Rock
U-Turn
I tried Mesprit here, and in the initial testing, it worked great. However, it didn't keep up it's usefulness. The main reason I choose Uxie of Mesprit is Yawn and it's ability to hang around longer. Even if this does put me at a disadvantage against Roserade leads, I find it overall more useful. Yawn forces switches to rack up Stealth Rock damage and give me free turns for Stealth Rock/Trick Room set up, and by not using a -Spe nature or a 0 speed Iv, he can utilize a "slow" U-Turn in Trick Room to safely bring in a sweeper. Overall, the most reliable lead I have used.
Dusclops @ Leftovers
Pressure
Relaxed
252 HP/36 Atk/200 Def/20 Sp Def
Shadow Punch
Will-O-Wisp
Trick Room
Pain Split
Originally I had a Porygon2 here, but then snorlaxxz helped me realize that Dusclops works much better as a spin blocker/trick room setter upper. He can spread status to help with safe switch ins, and can kind of heal himself with Pain Split. A very good asset to my team. Thank you snorlaxxz!
Porygon2 @ Leftovers
Download
Quiet
252 HP/120 Def/136 Sp Atk
Trick Room
Recover
Ice Beam
Thunderbolt
After getting rid of Porygon2, I decided to bring him back over Slowking. He gives me a welcome immunity to ghost and non-weakness to dark, which is beyond useful on a Trick Roomer. Boltbeam is awesome, as usual, and will help with that glaring Tangrowth walling I had. If there is a set that would fit my team better than the one here, let me know!
Marowak @ Thick Club
Rock Head
Brave
252 HP/252 Atk/4 Def
Earthquake
Stone Edge
Fire Punch
Double-Edge/???
An obvious choice for a Trick Room team. Thick Club boosts his already good attack, and Trick Room turns his slow waddle into a massive sprint. Earthquake gets STAB and does massive damage, so it is an obvious choice. Stone Edge damages flyers that switch into Earthquake, Fire Punch beats down grass types that give my team trouble, and Double-Edge is just filler, so I am open to suggestions about other options for this slot. Unlike other members of my team, he does not like to switch in multiple times and often only comes in after a pokemon faints or when Uxie is able to U-Turn him in safely.
Cacturne @ Expert Belt
Sand Veil
Brave
4 HP/252 Atk/252 Sp Atk
Seed Bomb
Superpower
Dark Pulse
HP [Fire]
Originally I tested Blaziken and Honchkrow for the slot of wallbreaker. They worked....sort of. Milotic was destroying my team though. Then Sidd gave me the suggestion of Cacturne. He works very well as a wall breaker, and has become a useful member of my team. Seed Bomb gets STAB and helps with Milotic, Superpower decimates Chansey, Dark Pulse gets STAB and hits Mismagious, and HP [Fire] damages Roserade. But since this is also trick room, he makes for a great sweep ;).
Trapinch @ Life Orb
Arena Trap
Brave
252 HP/252 Atk/4 Def
Earthquake
Crunch
Rock Slide
Quick Attack
:). What else is there really to say? Trapinch shines in the late stages of the battle when the opponents ground immunity has been removed by the other sweepers and he can trap and kill almost anything in the metagame. Earthquake is STAB, crunch gets psychics/ghosts/exeggutor that give my team trouble, and rock slide ruins flyers and bugs. Quick Attack picks off weakened priority users such as Azumarill. Life Orb gives extra power, as recoil is not an issue: he dies in one hit regardless. I have debated choice band for extra power, but do not like the idea of being locked into earthquake in a bad situation. Despite his appearance, Trapinch can actually be a force to be reckoned with in UU play with a 328 attack stat.
Overall, I have tried to make a strong Trick Room team, while keeping a few unique pokemon. Anyone is open for replacement except Trapinch, as the whole point of the team is to create an environment for him to shine and become king of the waddle/sprinters. If anyone has ideas to help with my glaring water/grass weakness, I am all ears. Any comments are appreciated, and thanks for reading my RMT.
