If Sett uses his legend ability to save a unit during a Showdown, does the Showdown still occur and both units die, or does the Showdown disappear?

Ruling: The Showdown occurs as normal and both units kill each other. Sett can then use his ability to save and recall the unit to base.

Sequence:

• Showdown occurs between the units
• Both units die in the Showdown
• Sett's legend ability triggers to save the unit
• The saved unit is recalled to base
• No unit remains at the battlefield
