Suppose I assign a lion personality at Province A, leaving provinces B, C, and D. My opponents assigns his defenders to oppose my unit at province A. I choose to first resolve the battle at province B. My opponent passes and on my turn I play lion's strength targeting my personality at province A. And I move his unit to the current battlefield (B) fulfilling both rule of presence and location. Am I missing anything?
Lion's Strength Battle: Target one of your opposed Lion Clan Personalities: Target a Personality not at the current battlefield. Move him to the current battlefield. Straighten him if you do not control him.
