Mind you, these are all the models I currently have (besides an Archon and another Haemonculus), but I'm working on planning on getting another Venom next.

Illegal list. You need to have 2 troop choices, take another look and repost list and we can get a better understanding of what you need.

With most of the people I play with, there's a house rule that the only FOC requirement for a 500 point game is one Troops choice. However, I could easily split the Wracks into 2 squads- one of 4 and another of 5 with the liquifier.

The only scoring unit in your list is in a fragile transport. Not the greatest idea IMHO.

For these point levels, I prefer Haywire Wyches instead of Blasterborn for my AT. More bodies to soak up wounds, and more bodies = more units = higher target saturation.
