As a person who played the renfri soldiers assimilate hybrid all season, nauzicaa is a busted pointslam that has a way to easy to fulfill condition.
Here is my proposition for the card change in the future.
4 power 5 provisions. Exactly as it is now.
Change the deploy ability into an order and give the card zeal. Keep the existing requirement to lose a round before the order is available.
Give the order BARRICADE requirement.
Now, if you want to spawn and play battle prep on the turn you play the Card you either need to run the imperial formation leader and spend a charge, which implies saving charges for round 2/3. Or you run it in other archetypes but need to include cards that give allied cards armor such as mantlets or iron falcon troubadours, or if you’re running it outside of renfri lists, war council order or using the order of a nauzicaa sergeant played last turn.
