I'm no good at rating, but let's see…
Kingler
Item: Choice Band
Rock Slide
Swords Dance/Brick Break
Crab Hammer
X-Scissor
If he can survive to set up Swords Dance this works but his Sp Def is terrible and Speed average at most. Consider Brick Break to deal with steel and dark.
Roserade
Item: Black Sludge
Sleep Powder
Energy Ball/Grass Knot
Shadow Ball
Sludge Bomb
Roserade is kinda sweepish so he needs plenty of attacks. I would prefer a quick Sleep Powder since he has above average speed. He can't really outlive the opponent even with Toxic
Typhlosion
Item: Choice Specs/Maybe Power Herb for an emergency Solarbeam?
Sunnday
Solarbeam
Flamethrower
EarthQuake
Poor Typh lack good moves :sad: But I like this moveset. EQ wipes dangerous rock-pokemon and other fires.
Miltank
Item: Leftovers
Thunderwave/Heal Bell
Brick Break
Milk Drink
Return
This one is cool. Hope it has the Scrappy trait. Thunderwave is mostly for annoyance and Milky already has great speed so Heal Bell is an option.
Hitmonchan
Item: Choice Band/Life Orb
Thunder Punch
Ice Punch
Sky Uppercut/Close Combat
Agility
Not so sure about this guy but if Iron Fist applies to Sky Uppercut go with that, otherwise Close Combat. One Agility and Chan will be faster than most pokés, he needs to be fast to sweep.
