I would like to suggest a change in Qwilfish since is a little forgotten:
Basically give him as Passive: Harden since it has a bit lower hp (22k although it has protect) harden would give more advantage in both duel and level, then Poison Jab based on bulbapedia Qwilfish learn it from level and here he drops the Tm and doesnt even have the move, next since Qwilfish is weak to Psy type, the move Destiny Bond is a good way to get to defend himself in the duel part for example in a duel with Delphox (fire-psy) Qwilfish lost easily and then the move Spikes goes for immunity to poison from the Steel type pokemons.
Every Proposition has been made based on Bulbapedia.
Original move set:
M1 Poison Sting
M2 Sting Gun
M3 Bubblebeam
M4 Water Shuriken
M5 Surf
M6 Toxic Spikes
M7 Scald
M8 Fell stringer
M9 Protection
M10 Brine
To:
Passive Harden
M1 Poison Jab
M2 Water Gun
M3 Bubblebeam
M4 Water Shuriken
M5 Surf
M6 Destiny Bond
M7 Gunk shot
M8 Fell stringer
M9 Protection
M10 Spike
