Well, I saw some other threads about Gym teams so I decided to experiment on this for a few days. There's one thing I noticed about Psychic types, and most of them have lower speed than average. So, I made a team that builds on slow Psychic types, and covering the different weaknesses of Psychic. Trick Room works amazingly on this team, but it was kinda weird when I ran into another Trick Room Team. Of course, everyone has 0 Spe IVs.
Mesprit @ Leftovers
Trait: Levitate
EVs: 252 HP / 180 Def / 76 SDef
Relaxed Nature (+Def, -Spd)
- Trick Room
- Thunderbolt
- Ice Beam
- U-turn
Mesprit is a great Trick Room lead. It has below average speed and it can kill off several leads after a Trick Room. I notice most leads try focusing on being fast, so Mesprit's below average speed and very good all around stats make him a prime choice for setting up Trick Room for my team. Then the BoltBeam combo let's me hit nearly everything. U-Turn is for scouting any incoming threats.
Slowking (M) @ Life Orb
Trait: Oblivious
EVs: 252 HP / 252 SAtk / 4 SDef
Quiet Nature (+SAtk, -Spd)
- Trick Room
- Ice Beam
- Surf
- Nasty Plot
There can never be too many Trick Room users on a Trick Room team, so I chose Slowking as an alternative way to set up Trick Room, just in case Mesprit dies. As one of the slowest Pokemon, he can easily move before the opponent. For offense, he also acts as a Nasty Plot Sweeper. After a few Nasty Plots, I reset Trick Room, then proceed to sweep the rest of the team.
Claydol @ Leftovers
Trait: Levitate
EVs: 252 HP / 144 Atk / 112 Def
Relaxed Nature (+Def, -Spd)
- Rapid Spin
- Stealth Rock
- Stone Edge
- Earthquake
Claydol is my utility Pokemon. He has very good defensive stats, has the ability to set up Rocks, and Spin at the same time. Stone Edge is the primary STAB move, and can kill off pesky Bug types, and Earthquake is for switch ins that resist Stone Edge.
Metagross @ Leftovers
Trait: Clear Body
EVs: 252 HP / 236 Atk / 20 Def
Brave Nature (+Atk, -Spd)
- Meteor Mash
- Earthquake
- ThunderPunch
- Ice Punch
Metagross, is always amazing on Psychic team. His speed isn't very high, so he's a nice addition for this team. His moveset gives him near perfect coverage. He has fantastic defense, and especially Attack. Ice Punch and Thunder Punch is kind of like a BoltBeam combo but physical so basically just those two attacks provide good enough coverage, and Meteor Mash is a great STAB move and finally Earthquake for electric and fire switch ins.
Gallade (M) @ Life Orb
Trait: Steadfast
EVs: 252 HP / 252 Atk / 4 SDef
Brave Nature (+Atk, -Spd)
- Swords Dance
- Close Combat
- Stone Edge
- Psycho Cut
Gallade, his Speed is also below average, so he's my Swords Dance sweeper, and he's great for this team. After a few SDs, he becomes force to be reckoned with, sometimes, ripping apart a whole team. Close Combat is a great STAB move, and the Defense effect will not be much of a bother, since I will outspeed a lot of Pokemon anyway. Psycho Cut is a reliable STAB move, and it works great in conjuction with Close Combat. Finally, Stone Edge is for Flying types.
Exeggutor (M) @ Leftovers
Trait: Chlorophyll
EVs: 144 HP / 112 Def / 252 SAtk
Quiet Nature (+SAtk, -Spd)
- Sleep Powder
- Trick Room
- Psychic
- Leaf Storm
My last Trick Room user if all else fails. I wanted one more heavy hitter, and with Exeggutor's low speed, high Special Attack, ability to set up Trick Room, and to induce sleep makes him a good candidate for the last slot. I needed one more Trick Room user, and, it sort of feels like what Blue did. Leaf Storm is for Water types, preferably the bulky kind. Psychic is for a powerful STAB, and Sleep Powder is to status the enemy to be able to set up either for myself or my team mates.
Any comments, or suggestions?
