More JML Talk

I played Legion in mk2 and sold them off. Looking to get back into the game with a JML.

I can choose between these 4 casters to start:
Abby2
Kryssa1
Saeryn1
Vayl1

We start at 0pts and increase by 15 each week. Can start using themes at week 3(30pts) and can add BEs week 6 (60pts).

Im eventually wanted to build out a 2 list pairing of oracles with lots of spells and Primal terror with lots of beef. I was recommended starting the JML with Saeryn1.

Was thinking:

Legion Army - 0 / 0 points

[Saeryn 1] Saeryn, Omen of Everblight [+28]
- Carnivean [18]
- Nephilim Bloodseer [8]

Then

Legion Army - 12 / 15 points

[Saeryn 1] Saeryn, Omen of Everblight [+28]
- Carnivean [18]
- Nephilim Bloodseer [8]
- Seraph [14]

Then

Legion Army - 30 / 30 points
[Theme] Oracles of Annihilation

[Saeryn 1] Saeryn, Omen of Everblight [+28]
- Carnivean [18]
- Carnivean [18]
- Nephilim Bloodseer [8]
- Seraph [14]
Blighted Nyss Sorceress & Hellion [0(6)]


Does this seem like the right track to take?
