White 2 PWT Team

So, I've been using this team and while it has worked wonders, I'm kinda bored of Alakazam so I'm kinda considering using somebody else, anyways the team right now is:

Neesha
Hydreigon @ Wise Glasses / Levitate
Modest 4 HP / 252 SpA / 252 Spe
-Dragon Pulse
-Dark Pulse
-Flamethrower
-Sur
I usually lead with her, pretty much getting rid of entire teams, This set has proved to be quite good, So I'm not rly considering to make any changes at all.

Abhik
Garchomp @ I DONT KNOW! I just gave her a Dragon Gem / Sand Veil
Jolly 4 HP / 252 Atk / 252 Spe
-Outrage
-EQ
-Stone Edge
-Brick Break
My physycal powerhouse, she gets rid of almost anything, Dragon Gem'd Outrage is huge damage. I'm thinking about slapping a Focus Sash on her, she's been OHKO'd by those damn Weaviles many times... Brick Break por coverage, Considering to change SE for Rock Slide, not sure yet, suggestions?

Mahin
Alakazam @ Life Orb / Magic Guard
Timid 4 HP / 252 Spa / 252 Spe
-Psychic
-Energy Ball
-Shadow Ball
-Focus Blast

Dont get me wrong, this guy is a killer, has awesome speed (31 Speed IVS) and Magic Guard is an awesome ability, free boosts from Life Orb mean huge damage. Psychic over Psyshock, I used shock first, but it proved to be kinda pointless, This guy can OHKO Blissey with Focus Blast anyways; Energy Ball and Shadow Ball for coverage, I hate Focus Blast, it misses way too much :/

So this is the team as of now, I'm considering to change Alakazam since I rarely use him, any suggestions?
