2000 Points Mixed Order Magic Heavy list (MAGICAL SUPREMACY battleplan)

[Maturin]

Hi guys,

I'll be playing this saturday at 2000 points, a mixed order army, against a guy playing Legions of Nagash specifically I think he's going to play the Death March Battalion + Vampire lord on Dragon Zombie, at least one or two units of Blood Knights, and some Black Knights.

The battleplan is straight forward, it's going to be MAGICAL SUPREMACY, :

OBJECTIVES
This battle is fought to control 2 objectives. Each is located on the centre line, 12" from the edge of the battlefield as shown on the map.
SUPREMACY
Add 2 to casting rolls for WIZARDS within 6" of any of the objective markers.
GLORIOUS VICTORY
Players score victory points for
the following:
• 1 victory point each time a WIZARD from their army successfully casts a spell within 6" of an objective marker
• 1 victory point for unbinding or dispelling an endless spell
• 2 victory points for slaying an enemy WIZARD that is within 6" of an objective marker
• 1 victory point for each objective they control at the end of the battle

So here's my list :

Allegiance: Order - Mortal Realm: Ulgu

LEADERS
Celestial Hurricanum With Celestial Battlemage (380)
- General
- Command Trait : Inspiring
Archmage (100)
- Steed
Loremaster (140)
Anointed of Asuryan on Frostheart Phoenix (320)
Battlemage on Pegasus (160)
Assassin (80)
- Artefact : Sword of Judgement

UNITS
10 x Longbeards (100)
- Great Axes & Shields
10 x Irondrakes (180)
20 x Freeguild Handgunners (200)
10 x Freeguild Handgunners (100)

ENDLESS SPELLS / TERRAIN
Balewind Vortex (40)
Chronomantic Cogs (80)
Emerald Lifeswarm (50)
The Burning Head (30)
TOTAL: 1960/2000 EXTRA COMMAND POINTS: 0 WOUNDS: 93
LEADERS: 6/6 BATTLELINES: 3 (3+) BEHEMOTHS: 2/4 ARTILLERY: 0/4
ARTEFACTS: 1/1 ALLIES: 0/400

What do you think of it ? I madesome lists including 30 PG, some GG instead of Handgunner's, but points skyrocketed and I didn't have enough points left for wizards. I'd like to squeeze in a Stardrake for the +1 to cast, bu also very expensive and not a wizard!
Since I'm very unlucky with rolls in general, I can't get rid of the Hurricanum, it's a very good investment for me, as well as the rerolls given by the Loremaster's spell.
The burning head will be cast in my backyards, I'll be using to give myself rerolls of 1's for my shooting units. At first I had put a Knight Azyros, but the head makes me save 70points, wich can allow me to take an assassin to be able to one shot, I hope, his Vampire Lord on ZDragon.
I'll be happy to hear your thoughts about that list.
