2500 Tomb Kings

So I need to get my army painted for the GT in november at Showcase Comics. I'd really appreciate some advice on what to take.

Here the models I have

4 liches
1 tomb king
necrotect
prince apophas
55 archers
6 chariots
10 light horsemen
40 tomb guard
3 necropolis knights
1 scorpion
catapult
casket

Any and all help would be appreciated.

Looks good - seems like too many point in characters in my opinion. What items and banners are you thinking about? I would take more than 3 necropolis knights if you can manage and/or get a warsphinx in there - they are amazing infantry killers.

Well I don't have much money, but I might be able to get a box of knights or a sphinx in before the tournament. I had been using the BOTUL but I haven't really been getting a sense of it being that useful. For 2 dice i can cure a decent amount of troops and slap a buff on them too.

Liche High Priest w/ Earthing Rod, Healing Potion, Lore of Nehekarah
Liche High Preist w/ lvl 4, 5+ Ward, Lore of Light

Tomb Prince w/ Charmed Sheild, Light Armour, I10 Sword, Potion of Strength
Necrotect- Dragonbane Gem, Ironcurse Icon
Prince Apophas

8 Chariots w/ Banner of Eternal Flame
19 Archers w/ Banner
18 Archers w/ Banner

30 Tomb Guard w/ Full Command, Razor Standard
3 Necropolis Knights w/ Champion, Entombed Beneath the Sands
Tomb Scoprion

Casket of Souls
Screaming Skull Catapult

I got like 20 more points to play around with... but so far i'm liking it. Not as many necroknights as I'd like but whatever
