THANKS again :D

Alakazam is a bit too frail to pull off a TrickOrb set. It's best off as an all-out attacker:
-Substitute/Calm Mind
-Psychic/Psyshock
-Shadow Ball
-Focus Blast
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Life Orb/Leftovers
Ability: Magic Guard

Lanturn lacks STAB attacks whatsoever, which hurt. A special tank set could help here:
-Scald
-Ice Beam
-Thunderbolt/Discharge
-Heal Bell/Thunder Wave
Nature: Calm
EVs: 40 HP/192 Def/100 SAtk/176 SDef
Item: Leftovers
Ability: Volt Absorb

or
-Thunder Wave/Discharge
-Confuse Ray
-Surf
-Ice Beam
Nature: Calm
EVs: 40 HP/192 Def/100 SAtk/176 SDef
Item: Leftovers
Ability: Volt Absorb

Snorlax isn't a good RestTalker unless it's using Whirlwind with entry hazard support. Spiritomb can fill in for it due to its lack of weaknesses:
-Calm Mind
-Dark Pulse
-Rest
-Sleep Talk
Nature: Bold
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers

For Gallade, you can give it Trick over Earthquake to screw over walls. You can also mix and match the last 2 slots in its set to deal with threats your team has a hard time with, as seen here:
-Close Combat
-Trick
-Ice Punch/Stone Edge
-Zen Headbutt/Night Slash
Nature: Adamant/Jolly
EVs: 4 HP/252 Atk/252 Spe
Item: Choice Scarf

Use Double-Edge instead of Toxic on Staraptor and give it Life Orb. Sure, it'll die quicker, but it'll have some form of neutral coverage other than Brave Bird. It's also a bit frail to use Toxic effectively.

Why doesn't Porygon-Z have Tri Attack? Without it, Adaptability is useless. Use this instead:
-Nasty Plot
-Tri Attack
-Dark Pulse
-Hidden Power (Fighting)/Substitute
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Life Orb/Leftovers
Ability: Adaptability

I'd say thick fat over immunity since your gonna rest anyway and why no STAB on porygonZ? other then that looks pretty good
