Okies. Looking for some constructive criticism on a 50pt Lich Lord Asphyxious list I'm intending on using at an upcoming tourney.

Lich Lord Asphyxious (6+ WJP)
Deathjack 12
Cankerworm 5
Nightwretch 4

Max Bane Thralls 8
+UA 3
Min Bloodgorgers 5
Bane Lord Tartarus 4
Gen Gerlak Slaughterborn 3
Saxxon orrik 2
Withershadow combine 5
Warwitch siren 2
Bloat Thrall 2
Necrotech and scrap thrall 1

Reserves - Harrower 10


The only thing I can really see as a problem with this list is the lack of pathfinder if I come up against a list with area denial like pIrusk or anything with inhospitable ground, which is why I brought orrik.
The only other thing I am unsure of at the moment is the reserves. Was thinking that the other option of taking would be a full 10 man unit of bane knights, but I like the anti infantry potential the harrower has, at range and in melee, plus it gives me another jack beatstick in the army.
