This entry is a modified version of demon Angron. As such, I have moved his retinue to Codex: Space Marines. It would be possible to swap the Vanguard Veterans to Wolf Guard if you wanted to use Codex: Space Wolves instead.
This entry is originally from a Apocalypse Datasheet published in White Dwarf. Since we have an official listing for a primach (albeit a demon one), Angron will be the basis of all future builds, structured around an Apocalypse Datasheet. This doesn’t mean that Primarchs can only be used in Apocalypse, but that they are pointed around the game. I would suggest at least 1750+ points to help keep the field level, as the units may be seen as game-breaking otherwise.
