World eaters
death guard
Thousand sons and actually
red Corsairs, simply bevause the tyran of badab is awesome

Thousand Sons and Red Corsairs

Sticking with the theme of Chaos Undivided, it'll likely (and should be) the Alpha Legion. Unless them, then either the Crimson Slaughter or the Blood Gorgons which are GW's new babies, both of which were featured with the new sixth ed.

W T F, lol.

Death guard!

I am Alpharius
Alpha Legion!!!!

I see Alpha legion being in this because they bring the sabotaging aspect to the game.

Death Guard, World Eaters and Thousand Sons. In that order. I will cast my vote so that even one of those legions have a better chance to make it into the game over any other warband or legion.
