Sir We have question to ask about using Imperial Deployment as action in limited. Then I will announce to attack the enemy province after I destroy his province. He use a retribution or The perfect moment . We want to know if may unit will straighten after he announce the action? Thank a lot if this question is to be answer.
Imperial Deployment Open: Choose your performing Personality: The Empress dispatches him to the Colonies. Negate other players' cards' effects that prevent him from assigning. After the next time this turn an attack is declared, straighten his unit.

Imperial Deployment says "next time this turn". That means you don't get to choose. If you use Imperial Deployment during your Action Phase, and then you declare an attack, that's the point when the straightening effect will trigger, that's the "next time this turn an attack is declared". This means that, if the Personality is unbowed, the effect will fail and be gone forever. Any further Attack Phases that turn (such as Retribution or Perfect Moment) will not straighten the Personality because they're not "the next time".
