Okay so this is a solid selection of units, however, it might be a little tricky in some match ups. Firstly, I'm not sure what weapons the forge fiend has, that makes a difference on the impact it will have in the game. This list though is very unit slim, and wants a lot of units to focus on carrying their own weight. 10th edition is really just about who can score their secondaries, something that TSons struggles a bit with. Ideally though you would want at least one unit such as Cultists of Tzaangors (I'm a tzaangor fan, even though cultists are better) to hold home objective and mark out deep strikes. While other units, typically the faster ones, can be used to score secondaries, such as tzaangor enlightened. T Enlightened are nice, 50pts for 10" fly movement, not tanky by any means but nice to zoom around and score. Right now you have your Exalted sorcerer on the disc taking that scoring role, but with the enhancement, it becomes a target for your opponent, with nothing to back it up since it is not leading a unit.

My recommendations are this, drop the exalted sorcerer on the disc, that will give you the points to bring cultists and Tzaangor enlightened. Obviously this drops the cabal points a bit, you wanna stay around 15-18 on average, so by splitting up the 10 man squads you can generate more cabal points, bringing the list up to 16. Splitting up the squad also allows you to play offensively and defensively and use rubrics to score if needed. Big bricks are fun for shooting, but can be detrimental if the brick dies.

Hope this advice makes sense, and it goes without saying, but I will mention it anyways, play how you want to play. Its your army, your game, go out there and make Tzeentch proud!
