2000 Point Skaven Tournament list for the weekend

[Lukes1504]

Hey all just wanting to get some thoughts on this list i will be using at a tournament on the weekend.
The general plan is to use the blocks of skaven slaves to hold against front charges allowing my better and i use the term loosely lol skaven units to flank charge the enemy. My opponents armies will be wood elves, high elves, dark elves, ogre kingdoms, warriors of chaos, lizardmen and orcs and goblins.

Army List is as follows.

Grey Seer with talisman of preservation, dispel scroll, skalm

Warlock Engineer with doomrocket
Warlock Engineer with death globe
Chieftan with halberd, battle standard, armour of destiny

30 Clanrats with shields, full command, poisoned wind mortar
30 Clanrats with shields, full command, warpfire thrower
30 Stormvermin with shields, full command
30 Skavenslaves
30 Skavenslaves
27 Giant Rats with 3 Packmasters

6 Gutter Runners with slings, poisoned attacks

Hellpit Abomination
Warp Lightning Cannon
Warp Lightning Cannon

In the army the warlocks join the two slave units to give them base leadership five plus the rank bonus for strength in numbers, the chieftan will go with the stormvermin and the grey seer will join a units of clanrats.

General plan is to set the two units of slaves up as a screen and force my enemies to charge or be charged moving my other units armound the flanks and rear. The gutter runners will take care of any pesky lone characters, mosters or fast cavalry while the two warp lightning cannon shld destroy units on their own.
