I can help you the best i can :) Im admiring how you use Togekiss :D
Try my strategy for Togekiss?
Modest / Timid Togekiss
EV's on either Spe/SpD or Spe/SpA or SpA/SpD
I use Sweet kiss on everything that learns it
Ability Serene grace + Air slash = 60% chance to flinch
Roost for SpD Investment, Tailwind for Spe Investment
Nasty plot for SpA Investment / Thunderwave for SpD/Spe Investment
This is my choice
Modest Togekiss
EV's on 100 SpD / 156 Spe / 252 SpA
Sweet kiss
Air slash
Tailwind
Nasty plot
But, this whole thing is just a suggestion.
hope i helped!
Paralysis is more reliable than confusion, as the opponent is forced to miss a turn 25% of the time. Paralysis also significantly lowers the victim's Speed, compensating for Togekiss' own not-so-stellar Speed:
-Nasty Plot
-Air Slash
-Thunder Wave/Heal Bell
-Roost
Nature: Timid
EVs: 252 HP/80 Def/176 Spe
Item: Leftovers
Ability: Serene Grace
Out of your list of current six, I'm afraid that Weavile, Altaria, Cresselia, and Togekiss (to an extent) are the most viable options. Audino is straight-up outclassed by walls like Cresselia itself and Hippowdon because of its lack of resistances. Get Aegislash back in there, too:
Weavile:
-Knock Off
-Icicle Crash
-Ice Shard
-Low Kick/Pursuit
Nature: Jolly
EVs: 252 Atk/4 Def/252 Spe
Item: Life Orb/Focus Sash
Ability: Pressure
Cresselia:
-Psychic/Lunar Dance
-Ice Beam
-Thunder Wave/Toxic/Trick Room/Lunar Dance
-Moonlight
Nature: Bold
EVs: 252 HP/252 Def/4 SDef
Item: Rocky Helmet
Aegislash sets if you're interested:
-Shadow Ball
-Flash Cannon/Sacred Sword
-Shadow Sneak
-King's Shield
Nature: Quiet
EVs: 252 HP/252 SAtk/4 SDef
Item: Leftovers/Weakness Policy
or
-Substitute
-Toxic
-King's Shield
-Flash Cannon/Shadow Ball
Nature: Modest/Timid
EVs: 252 HP/252 SAtk/4 SDef (Modest) or 252 HP/4 SAtk/252 Spe
Item: Leftovers
or
-Iron Head/Shadow Claw
