I just beat Drayden (7th Gym). I also need 1 more pokemon to fill in because Ducklett is just a slave, RMT and suggestions would be nice for a 6th Pokemon.
Scolipede (Max) LV:46 @Poison Barb
1. Steamroller
2.Bug Bite
3.Toxic
4.Venoshock
I would honestly ditch this Pokemon. It doesn't get good coverage with its moves post-game, which is not worth the hassle.
Emboar (Bacon) LV:48 @Rocky Helmet
1.Flame Charge
/thrower
2.
Scald
3.
Wild Charge
4.
Hammer Arm
This set gets unresisted coverage and can decimate everything.
Ampharos (Voltage) LV:46 @Magnet
1.Discharge
(replace with T-Bolt when it learns it)
2.Volt Switch
3.
Focus Blast
4.Thunder Wave
No point in having a Physical electric type move as it is going to be weaker even against physically weak Pokemon.
Flygon (Gunter) LV:48 @Ground Gem
1.Dragon Tail
(replace with D Claw when it learns it)
2.
Fire Punch
3.
Bulldoze
4.
U-Turn
Lucario (Liu Kang) LV:48 @Expert Belt
1.Swords Dance
2.Extremespeed
3.Close Combat
4.Ice Punch
