Everybody seems to be building lists of only stuff they have on them right now,
wysiwyg and already assembled and painted and all that instead of theorycrafting. I'll throw in my lot

I'll jump on the bandwagon. Here's 1850 points of very casual models in my collection
HQ:
Captain in Terminator armor with dual lightning claws, 155
Captain in Terminator Armor with Sword and
SB 140 (could be a Libby if he had a hood but it's definitely the Captain model)
Elites:
5 tactical terminators, one assault cannon 230
Sanguinary Priest, barebones - 50
Sanguinary Priest with Jump Pack and Infernus pistol - 90
Troops:
5x assault marines, sarge has a power sword, in a Land Raider Crusader
DT with a Multimelta - 340
10x assault marines, two melta guns, sarge has power axe and infernus pistol - 240
5x assault marines, one plasma gun, in a Razorback
DT with Twin linked assault cannon - 170
5x scouts with snipers and camo cloaks - 90
Fast Attack:
Flamestorm Baal Predator with Heavy Bolter Sponsons - 145
Heavy Support:
Storm Raven with
TL Multi Melta and
TL Lascannons - 200
All termies and the barebones Sang priest (he could pretend to be Corbulo?) go in the Crusader, the displaced Assault Marines go in the Storm Raven for a Turn 5 hover charge to try and win an objective. Reserve: the SR (duh), Flamestorm Baal for outflanking,
AC Razorback to protect it and the Jumpers can either reserve to Deep strike to shoot for Rear armor or fly up the middle with the
LRC to help out cracking transports and assaulting things that need to be assaulted.
It's different. I'll give it that much. No one would see this list coming. Then again there's nothing gimmicky about it to use that surprise to it's advantage.
I have some other models I could use (
lol Sanguinary Guard and tactical marines) but this is what I came up with at the drop of a hat. Let me know what you think!
