When Leona enters a battlefield with 2 units, stuns the stronger one, kills the weaker one in showdown but cannot conquer due to the stunned unit still being present, what happens to Leona?

Ruling: Leona is recalled to Base in whatever State she was in on the battlefield (e.g., if exhausted, she returns exhausted). She cannot conquer the battlefield because the stunned unit is still present, even though it didn't participate in the showdown.

Sequence:

• Leona enters battlefield and stuns the 6-might unit
• Showdown occurs between Leona and the 3-might unit
• Leona kills the 3-might unit
• Since the stunned 6-might unit still occupies the battlefield, Leona cannot conquer
• Leona is recalled to Base in her current state
