Greninja is still the better Spikes lead over Froslass because of its better Speed and offensive presence:
-Spikes
-Hydro Pump/Surf
-Dark Pulse/Ice Beam
-Hidden Power (Fire)
Nature: Timid
EVs: 4 Def/252 SAtk/252 Spe
Item: Life Orb/Focus Sash

A Life Orb cuts into Dragalge's good bulk. It's still better off using Black Sludge as its item. Dragon Tail also works well with the hazards you put in:
-Toxic Spikes
-Sludge Bomb
-Dragon Tail
-Surf/Hydro Pump/Thunderbolt
Nature: Sassy
EVs: 252 HP/40 Def/216 SDef
Item: Black Sludge
Ability: Poison Touch

Assault Vest won't let Malamar use status moves, including Trick Room. If you want to use Assault Vest with Malamar, replace Trick Room with Rock Slide. Or, you can opt for any of these:
-Night Slash
-Psycho Cut/Substitute
-Superpower
-Topsy Turvy/Hypnosis/Light Screen
Nature: Adamant
EVs: 32 HP/252 Atk/224 SDef
Item: Leftovers
Ability: Contrary

or
-Rest
-Sleep Talk
-Night Slash
-Superpower
Nature: Careful
EVs: 252 HP/4 Atk/252 SDef
Item: Leftovers
Ability: Contrary

What's the deal with using Mime Jr. on the team as opposed to Mr. Mime? It's weaker and slower. Even then, Mr. Mime is only good for Baton Pass teams. Gardevoir is the better fit:
-Calm Mind
-Moonblast
-Focus Blast
-Shadow Ball/Thunderbolt
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Life Orb
Ability: Trace

or
-Wish
-Protect
-Will-o-Wisp
-Moonblast/Psychic
Nature: Calm
EVs: 252 HP/4 Def/252 SDef
Item: Leftovers
Ability: Trace

or
-Calm Mind
-Moonblast/Psychic
-Shadow Ball
-Focus Blast
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Gardevoirite
Ability: Trace

You already have Dragalge setting up Toxic Spikes for you so I'd replace Drapion with something more useful, like Crobat, who has Defog to clear away hazards:
-Brave Bird
-Taunt
-U-turn/Toxic
-Roost
Nature: Jolly
EVs: 120 HP/136 Atk/252 Spe
Item: Black Sludge
Ability: Infiltrator

or
-Brave Bird
-U-turn
-Defog
-Roost
Nature: Jolly
EVs: 252 Atk/4 Def/252 Spe
Item: Black Sludge
Ability: Infiltrator

I don't know how defensive Arcanine fares in the current meta, tbh. I think that something like Super Size Gourgeist can prove useful, as its high Defense can help with the team, or Trevenant, who can keep itself alive very easily:

Gourgeist (Super size):
-Will-o-Wisp
-Leech Seed
-Protect/Pain Split
-Seed Bomb/Shadow Sneak
Nature: Impish
EVs: 252 HP/4 Atk/252 Def
Item: Leftovers
Ability: Frisk

Trevenant:
-Horn Leech/Wood Hammer
-Earthquake/Rock Slide
-Will-o-Wisp
-Rest
Nature: Careful
EVs: 252 HP/140 SDef/116 Spe
Item: Leftovers/Lum Berry
Ability: Natural Cure/Harvest

or
-Substitute
-Leech Seed
-Will-o-Wisp
-Phantom Force
Nature: Careful
EVs: 252 HP/140 SDef/116 Spe
Item: Sitrus Berry
Ability: Harvest
