Does Ahri's Alluring ability affect only one character when multiple characters move to showdown, and when is the target declared? Does her leader ability affect one or all units?

Ruling: Ahri's Alluring character ability affects only one unit when multiple units move to a showdown at her battlefield. Her leader ability affects all units you move to a battlefield she controls.

Sequence:

• When you move a unit to the battlefield Ahri is occupying, at the beginning of the showdown, the opponent declares which unit is targeted by Alluring

Nuances:

• The character ability (Alluring) targets a single unit
• The leader ability applies -1 to each unit attacking a battlefield Ahri controls
