Since the battle which from now on I shall refer to as the "Serpent Spam incident" I mulled over my units and decided I needed to make some drastic list changes. So I put the Helblades to rest concluding that they are paper cannons (Can do a lot of damage, but die if someone sneezes on them) and replaced them with an extra unit of 5 Nurgle Spawn. I also decided to mount my warlord sorcerer on a bike to allow more maneuverability. Looking back on my previous game the spawn did really well considering I didn't know what the Wraith Guard weapons did, but you live on and learn.
This game has considerable alterations in how I worked my army and what tactics I used, especially playing Thunder Cav, drop pod space wolfs for the first time in 7th edition. This was a good game.
