Ok here is my first attempt at a RMT.
Hippowdon
Fine i like it, good job on that!
Scizor
Ok i have a few suggestions here. Change U-turn for Bug Bite and Roost for Super Power.
Apart from that nice one SF
Ferrothorn
Ok i am going to suggest Ferrothorn over Staraptor.
EV's: 252 Def 252 SpDef 4 HP
Trait: Iron Barbs
Item: Rocky Helmet
Moves:
- Leech Seed
- Power Whip
- Gyro Ball
- Payback
Now this can act as you staller but it can also attack the enemie. Power Whip is coverage against water types.
Jellicent
Another good job. Well done!
Reuniclus
I am going to suggest Reuniclus over Gengar.
EV's: 252 SpDef 252 HP 4 Def
Trait: Magic Coat
Item: Leftovers
Moves:
- Calm Mind (It was always going to be there :P)
- Psychic
- Shadow Ball
- Recover
Now this is your proper staller and all round power house. Magic Coat prevents Status, Hazards and Weather. Use Calm Mind to set up and then Baws with Psychic or Shadow Ball. Recover is there to heal along with Lefties.
Crustle
Fine, just fine. :P
Hope this helps! ^.^
