When Dazzling Aurora reveals Miss Fortune Bucaneer and plays her to an empty Battlefield, does it start a Showdown, and does the turn end immediately after that Showdown resolves?

Ruling: Yes, revealing and playing Bucaneer to an empty Battlefield starts a Showdown, and the turn ends immediately after that Showdown resolves if nothing else is triggering.

Sequence:

• Bucaneer is revealed and played to an empty Battlefield
• Showdown is initiated
• Showdown resolves
• Turn ends immediately (if no other triggers)
