Cool Throne of Skull army ideas

Hi all just come back from Throne of Skulls, had a wicked time won 3 lost 2 (One I blame hideous dice the other my own incompetance due to a horrific hangover).

I took a Codex Marine list 4 Razorbacks with assualt cannons, 3 vindicators, one assualt squad with Characters and extras to take it up to 1750. I really enjoyed my games and I liked my list alot.

Next year however requires a new army.

I saw some amazing armies there full armour Eldar lists, full Wraith Guard lists, all Khorne Chaos Marines, Ork Dred lists, Ork Battle Wagon Lists, Armoured Guard, All infantry Wolf lists, Vulkan Melta/Flamer lists, Draigo Wing lists. All sorts I'd like a bit of help thinking of an unusual but fun and effective list to build for next year.

My highlight was powerfisting Ragnar to death.

Ideas so far:
All Infantry Guard
All Hamouncllous Dark Eldar List
All Genestealer List
All Jump infantry list
Pure Tzeentch Deamons
Grey Knight Psychic Henchman list

All thoughts appreciated....cheers
Charlie
