Hordes: Morvahna the Dawnshadow Spoiler

Feat: Blood Sacrifice – Morvahna immediately suffers 1 or more damage points. This damage cannot be transferred. For each damage point she suffers, return one destroyed non-character living friendly Faction warrior model to play completely within Morvahnaʼs control area. Units cannot exceed the number of models that they had at the start of the game as a result of Blood Sacrifice. Place returned trooper models in formation with their original units. Returned models forfeit their actions the turn they return to play.

The rules for trooper models include officers as well as multi-wound models, so that means you can bring back cavalry, Tharn Ravagers or Bloodpack, or even models like Nuala or the Warpborn Alpha.  Just remember to bring some way to heal her up and keep her protected!
