I'm looking for ideas about building a Tzeentch themed LatD army. The main issue I'm struggling with is how to get a few units of Rubric marines in the army. Ideally I'd like 2-3 units of Thousand Sons, but the way I read it I can only have one unit. This unit would occupy the 0-1 Elite choice for the Chaos Codex option. If I give the Mark of Tzeentch to Chosen (another way to have marked marines), they all become sorcerors. I'd like to have 2-3 units of Rubric marines. Is there anything better than just one unit of 18 Thousand Sons?
Thanks,
Gorthrax
