Anyways here's the list

Lords

Enchanted Shield

Heroes
Chieftan
Enchanted Shield
Seed of Rebirth
Weeping Blade

Warlock Engineer (taking warp lightning)
Level 1
Warplock Pistol
Warp Energy Condenser
2 Warpstone Tokens

Core
40 Clanrats
Shields
Standard Bearer
Musician
Plague Wind Mortar

20 Clanrats
Shields
Standard Bearer
Musician
Warpfire Thrower

Special
2 Rat Ogres
Master Bred
Packmaster

I'm mostly just working with what models I have available. I do have a suitable proxy for a warp lightning cannon if needed but other then that these are all WYSIWYG models.

I plan to toss the grey seer and chieftan in the block of 40 amd march them up to distract the enemy while the group of 20 with the engineer goes up on flank and the ogres go up the other. My only real opponent that I can play regularly is a VC player but there are a few players at a GW store near me that play many other races.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/546914/5960157.page http://www.dakkadakka.com/dakkaforum/posts/preList/546914/5960157.page GMT are you looking for a crushing tournament style list or just something more friendly?
You're going to get a lot of advice about getting a hell pit abomination and/or the doomwheel and the lightning cannon.

I don't think the seer can take the shield because casters can't take armour.
You can only have 1 enchanted shield in your army. You can't duplicate magic items with a few exceptions from the scavenge pile.
It will be suggested that you turn your chieftain into a battle standard bearer with either the storm banner or the standard of discipline.
You can save points to get the banner by taking slaves or dropping the mortar.
Though tricky and terribly random you'll get far better results from the warpfire thrower.
I would definitely add the cannon it will give you something to hit big tough things with
It looks as if you pretty much have the island of blood miniatures...do you have anything else to add?]]> http://www.dakkadakka.com/dakkaforum/posts/preList/546914/5960205.page http://www.dakkadakka.com/dakkaforum/posts/preList/546914/5960205.page GMT VC. Any ideas as to how to expand upon my army would be fantastic since all I have is what you see on the list.

I didn't bother with the stormbanner since the VC player that I know uses little to no shooting which would render the banner useless.

I was using battlescribe to make this list I guess it needs to be edited a bit since it didn't catch that I had 2 enchanted shields and my grey seer had the option to take magic armour]]> http://www.dakkadakka.com/dakkaforum/posts/preList/546914/5960422.page http://www.dakkadakka.com/dakkaforum/posts/preList/546914/5960422.page GMT
Personally I dislike rat ogres, so if you need a place to get points (other than switching some clanrats to skavenslaves) I would suggest dropping them,]]> http://www.dakkadakka.com/dakkaforum/posts/preList/546914/5961877.page http://www.dakkadakka.com/dakkaforum/posts/preList/546914/5961877.page GMT
If those are the models you have there isn't much more you can do but go with it.

You can always get another island of blood to help with models. Or use eBay if you're on a budget.

The storm banner also stops flyers which can slow your opponent down.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/546914/5962971.page http://www.dakkadakka.com/dakkaforum/posts/preList/546914/5962971.page GMT

You might want to give the standard bearer a ward or better armor.
