DESIGN: Lamenters or Star Phantoms (Part 2)

Lamenters or Star Phantoms?

The Star Phantoms are one of the more enigmatic chapters. They do not have a confirmed legion of origin, and have little to no background to speak of
Therefore, it was such a surprise when one of their captains, the one known as 'Captain Androcles', wounded Huron himself during an attack on the Palace of Thorns
So, the Star Phantoms are also LOYALIST during the Babab war, and are also noted as using Drop Pods during their attack on the Palace of Thorns. Therefore, I will be using a Drop Pod Assault Army. Then we shall see what happens.
Here is the Home-Cooked Chapter Tactic:
Chapter Tactic (Vital Blow): Not all Star Phantom units gain this rule - only 3 units and all the characters may use it. When the unit is mounted in a Drop Pod, they may assault on the turn that they are deep striked, a lot like Heroic Intervention. However, they may run on the turn they are Deep Striked in, and count as having Fleet of Foot

This means that they are perfect when used with the Drop Pod Assault - you pick 3 awesome units in order to assault the foe. Then, you finish them off with the slower parts of your force!
Bearing this in mind, i'm thinking of using this as my Star Phantom army:

• Captain with Combi-Melta, Power Sword, Artificer Armour, Digital Weapons
• 10 Sternguard Veterans with Drop Pod, Vital Blow
• 5 Assault Terminators
• 10 Tactical Marines with Drop Pod, Vital Blow
• 10 Tactical Marines with Drop Pod
• 10 Tactical Marines with Drop Pod
• 5 Scouts with Sniper Rifles
• 10 Vanguard Veterans with Drop Pod, Vital Blow
• Land Speeder Storm
• 10 Devastator Marines with Drop Pod

~ So, this is part 2 of the article. Perhaps there are two more parts - I wouldn't want the Astral Claws to feel too lonely...
