I m going to the GT in London, and am currently trying to decide whereever or not to use my Grey knights or my Thousand sons, here is the force if I decide to go with Thousand sons
Zarathustra Suicune , exalted sorcerer on disc of Tzeentch and with Helm of the third eye
Ahriman on disc
10 Tzaangors with Tzaangor blades instrument of chaos
Rubric Squad Ptolemy:10, 8 inferno boltguns, one soulreaper cannon, force staff and plasma pistol.
Chaos Rhino with combi bolter
Rubric squad Belshazar: 7, inferno boltguns, inferno bolt pistol, force staff.
Chaos rhino with combi bolter and havoc launcher
Chaos Xiphon interceptor
Hellforged Chaos Contemptor dreadnought with chainclaw, butcher cannon and combi bolter
Ensharhaddon Raiku, terminator sorcerer with force staff, inferno combi bolter and spell familiar, warlord.
Hellbrute with twin lascannon and missile launcher
Hellbrute with hellbrute plasma cannon and missile launcher
Scarab occult squad Mithrandir:5, force staff, 4 power swords, 5inferno combi bolters, heelfyre missiles
With the changes to deepstriking, I am thinking of dropping the terminators in favour of a hellforged predator with lascannon sponsons and either the C beam cannon or a Plasma destroyer, if I did that I'd likely drop the exalted's disc, make him the warlord and put him with the tank dreads as a firebase.
If I did that I'd most likely try and squeze a unit of enlightened with bows in to act as a objective grabber/distraction.
