1750 Crowe - Advice Welcomed!-

I want to build a semi-competitive while fun list. The upcoming week I'm going to be playing against my friend who plays eldar, and so I came up with this list:

HQ: Castellan Crowe – [150]

Elite: Techmarine (90): Rad grenades (15), Psychotroke Grenades (10), Blind Grenades (5), 2 Servo Skulls (6) – [126]

Troops1: 10 Purifiers (240): 4 Psycannons (40), 3 Halberds (6), 2 Daemon Hammers (10), Knight of Flame with Halberd (2) – [298]
Troops2: 5 Purifiers (120): 2 Psycannons (20), 1 Halberd (2), 1 Daemon Hammer (5), Knight of Flame with Halberd (2) – [149]
Troops3: 10 Terminators (400): 2 Psycannon (50), 4 Halberds (0), 4 Swords (0), 2 Hammers (0) – [450]

Fast Attack: Storm Raven (205): Twin-linked multi-melta, Twin-linked lascannon – [205]

Heavy1: Dreadnought (115): 2 Twin-Linked Autocannons (15), Psybolt ammunition (5) – [135]
Heavy2: Dreadnought (115): 2 Twin-Linked Autocannons (15), Psybolt ammunition (5) – [135]

Transport1: Razorback with Heavy Bolter, Psybolt Ammunition (5), Flashlight (1) – [51]
Transport2: Razorback with Heavy Bolter, Psybolt Ammunition (5), Flashlight (1) – [51]

Total: 1750

I was considering cutting the termi squad to 5 man to add another purifier squad and razorback.

There are many options that can go with the list.

• Although I only could fit 2 servoskulls, it will help in deep striking the terminators or stormraven.
  
• The purifier/terminator squad can be broken into combat squads
  
• Either 10 man purifier or 5 man terminator can use the storm raven + Techmarine
  
• An extra razorback can be used for Crowe

Advice, ideas, or critiques are welcomed!
