ok so I have a few suggestions below
Ludicolo : blizzard imo isn’t very good in terms of accuracy, personally I’d go for ice beam. also replace surf with scald as it’s a better stab. although if you don’t have it surf is fine magic bounce is actually better than sync imo
D. Liepard a pretty bad mon. but if you give it choice specs/band might give it a good enough boost to be useful. also you may want to go with one type of move (Special/physical) below( if you want to be aggro)
sucker punch/foul play/ knock off
shadow claw/ phantom force
poison jab
play rough
you can also use focus sash swords dance/coil set with aqua tail instead of poison jab
you could also go with specs
sludge wave/ bomb
thunderbolt/ dark pulse/ energy ball/ hyper voice
moonblast
shadow ball
also a dumb support set
focus sash/ scarf
confuse ray/ thunderwave/will o wisp-/ moon blast
endeavor/ trick
confide/sub
double team
D. weezing I’m not sure about this one, you could go with a belly drum set
sitrus berry / 1/3rd berries
spark/ wild charge
bounce/fly
explosion/return
gunk shot
OR you can go special with an amplifier set with
specs/scarf
boomburst
heat wave
thunderbolt/voltswitch
hurricane
you could also go bulky/support with max defense
leftovers
thunderwave/toxic
roost
thunderbolt
light screen/ reflect
D. Huntail
well crippled a ton by it’s lack luster speed and 4x weakness to fairy. but you can go for a set I made
focus sash/life orb
dragon dance
sucker punch/knock off
outrage
a fang move
d. scizor replace false swipe with ice shard
(scyther is all around better lmao)
rock tomb is kinda ok for speed control although you can replace it with bulk up if you like
D. vespiquen so you usually are gonna want to go with a single a single type, but with lonely nature you can go with
iron head
flare blitz
swords dance
roost
lmk if you have any questions/ need help with post game tutors
