Universal Rule.
The model cannot be deployed during the Deployment Phase. Instead, at the start of any Player Turn, the owner may choose a friendly unit of Vermin Velites, Vermin Legionaries, Blackfur Veterans, Shadowfur Stalkers, or Ignifier Grenadiers that is not Fleeing and that the model can join, and apply the following rules:
• Remove a R&F model from the chosen unit’s first rank as a casualty. You cannot remove the last R&F model from a unit.
• Deploy the Duskblade Assassin inside the unit in the position of the removed model.
• The Duskblade Assassin cannot voluntarily leave its unit during the Player Turn in which it was deployed.
• If the model is not deployed by the end of Game Turn 4, it counts as a casualty and cannot be deployed for the rest of the game.
• The model cannot be deployed in a Summoned unit
