Does Ahri, Nine-Tailed Fox (Legend) give -1 might to every unit attacking a battlefield or just one? Does Ahri, Inquisitive work the same way?

Ruling: Ahri, Nine-Tailed Fox (Legend) gives -1 might to all units attacking her battlefield. Ahri, Inquisitive only targets one unit.

Sequence:

• When an opponent's unit is assigned as an attacker to Ahri Legend's battlefield, her trigger goes on the initial chain (before players can play actions)
• The -1 might applies to all attacking units at that time
• If a new unit joins combat later (e.g., via Ride the Wind after the initial chain resolves), Ahri Legend triggers again for that new unit
• The new trigger starts a new chain that players can respond to with reactions

Nuances:

• Ahri Legend can trigger multiple times in one combat if new attackers are assigned after the initial chain
• Ahri, Inquisitive only triggers once per combat
• Ahri Legend's trigger occurs during the initial chain, but once on the chain, players can respond with reactions
• When a unit joins combat via an action like Ride the Wind, it doesn't gain the attacker designation until that action resolves, so Ahri's trigger starts a new chain afterward
