7th Ed. 2 person team 9000 point megabattle

I'm doing this HUGE battle w/ my friends. I'm teaming up w/ a WE player, and we're playing against BoC and TK. What should I build my army around? I have:

1 Slann
2 Skink Priests
2x 12 Saurus
2x 20 Skink Skirmishers
3 Kroxigors
3 Chameleon Skinks
3x 5 Cold One Riders
2 Salamanders

What do I need to add, cuz i need another 2500-3000 points.

 

stegadons, temple guard, even more saurus warriors, old bloods/scar vets to bolster your units, a carno would be nice...
Add more priests, turn your cavalry into 2X8 or 2X10
EOTG's
Terradons


I think the question is, how big is your board?

-Eagle-

 

half of a basement. and the basement is enormous.

 

you might take a couple of slann's that way the magic phase will belong to you

 

Pack some flyers. Heh. Also go through the spells and look for things that take effect regardless of range, those will be helpful in such a massive game.

If you're talking ultra massive, you might just want to double everyone's movement and double all the relevant ranges.
