Alpha Sapphire Team Help

Hi all, I want to start Alpha Sapphire, but I cannot decide on the last spot for my team. It is purely for in-game use, so no competitive battling. These five I have so far:

Sceptile
-Leaf Blade (Energy Ball later)
-Earthquake
-X-Scissor
-Rock Slide or acrobatics

Gallade
-Brick Brace (Drain Punch later) or Close Combat (downside on Close Combat is the pp)
-Psycho Cut (Zen Headbutt later)
-Night Slash
-Earthquake

Tentacruel
-Sludge Wave
-Surf
-Ice Beam
-Dazzling Gleam

Magnezone
-Flash Cannon
-Thunderbolt
-Thunder Wave
-Signal Beam

Mega Altaria
-Fly
-Dragon Pulse
-Moonblast
-Flamethrower

Then the last spot, I'm doubting between Absol and Dusknoir. Both can act as counters for psychic and ghost pokémon. Absol does a better job typewise, but Dusknoir has high defenses. Furthermore, Dusknoir is also a good counter for poison types with EQ. The movesets I have in mind are as follows:

Absol
-Sucker Punch
-Psycho Cut (later Zen Headbutt)
-Stone Edge or Rock Slide
-Swords Dance

Dusknoir
-Shadow Punch
-Earthquake
-Fire Punch
-Brick Break

I'm curious about your opinion which of those two fits my team best. And also what some good alternatives for the moves would be. My team is very attack-oriented as I always play like that in-game, but if you know some useful status moves please let me know. Thanks in advance!
