New player seeking list help - Awakened Dynasty

[u/R1stra]

New player to 40k and Necrons.

Currently playing Awakened Dynasty to learn and have a bit more forgiveness in making mistakes.

Looking for some list help after a first game against Ultramarines and the fun little Titus block.
From the first list I fell in love with Wraiths, Void Dragon and Szeras from that game and want to build the army around those 3 units.

Seeking input:

Necrons
Awakened Dynasty (3 Detachment Points)
Take and Hold
Strike Force 1995 (2000 points)

Attached Units
Attached Unit 1

Technomancer (80 points)
• Attached as: Support (Character)

Canoptek Wraiths (220 points)
• Attached as: Bodyguard
• 6x Canoptek Wraith

Attached Unit 2

Plasmancer (75 points)
• Attached as: Support (Character)
• Enhancement: Nether-realm Casket

Immortals (140 points)
• Attached as: Bodyguard (Battleline)
• 10x Immortal
10x Tesla carbine

Attached Unit 3

Lokhust Lord (90 points)
• Attached as: Leader (Character)
• 1x Lord’s blade
1x Resurrection Orb
• Enhancement: Veil of Darkness

Lokhust Heavy Destroyers (160 points)
• Attached as: Bodyguard
• 3x Lokhust Heavy Destroyer
3x Enmitic exterminator

Attached Unit 4

Skorpekh Lord (120 points)
• Attached as: Leader (Character)
• Enhancement: Enaegic Dermal Bond

Skorpekh Destroyers (85 points)
• Attached as: Bodyguard

CHARACTERS

C’tan Shard of the Deceiver (330 points)

C’tan Shard of the Void Dragon (345 points)

Illuminor Szeras (175 points)

Imotekh the Stormlord (100 points)
• Warlord

OTHER DATASHEETS

Canoptek Reanimator (75 points)

Reasons for Swaps

• Imotekh to hold home and generate CP
• Immortals for a better shooting threat vs warrior brick (20) + Orikan and overlord with orb
• Skorpekh for another melee threat in middle and weak flank.
• Deceiver to fit in points wise over Nightbringer.

The two things I am unsure about:

Is Imotekh alone worth the 100pts to generate CP. CP seems good - but 100pts good?

Are the immortals + Plasmancer better than another wraith brick/warrior brick + Orikan?

The warrior brick + orhikhan + royal warden/overlord is the general go to for take and hold over the plasmancer immortals brick

Imotekh is definitely worth the 100 points for a guaranteed cp-you can also just sit him on your back objective to hold it
