This look really depressing, good thing Avengers will get some well deserved points decrease.
+1LD is worthless on aspect warriors, especially if you bring Khaines Avatar.
Boost to shuriken weapons already exists from the PL's and the Autarch, less PL's and Autarchs for biel-tan is counterfluffy.
The stratagems are neat though very costly so you need an Autarch to recycle CP's, wait Autarchs other ability is useless when playing biel-tan
Feigned retreat is probably most useful for shining spears, while the court is for Banshees, you still need that Avatar close by to take full advantage of the court, combined with Jain Zar this would just be CC-overload, so noone would ever go near them.
The last stratagem is actually quite nice, if not for the small detail it only works in the fight phase, I have NEVER lost an Avatar in CC in my 20+ years of playing. Lascannons and missile launchers is what kills Avatars.
The only thing that could save biel-tan would be Avenger spam, with DAVU returning for mechanized lists.
