When a unit is moved into combat after the initial chain (e.g., via Ride the Wind), does Ahri Legend's ability trigger to reduce that unit's might by 1?

Ruling: Yes, Ahri Legend triggers for each unit the first time that unit gains attacker status during each combat, regardless of whether it enters during the initial chain or later via effects like Ride the Wind.

Sequence:

• When units initially attack a battlefield defended by Ahri Legend, each attacking unit triggers Ahri's ability once and gets -1 might
• If additional units are moved into the same combat later (e.g., via Ride the Wind), each of those units also triggers Ahri's ability once when they first gain attacker status
• Each unit can only trigger Ahri's ability once per combat, even if that unit somehow leaves and re-enters the same combat

Nuances:

• Attack triggers occur "when a unit gains the Attacker designation for the first time during a combat"
• The "once per combat" restriction applies per unit, not per ability - Ahri Legend can trigger multiple times in one combat for different units
• If a unit somehow loses and regains attacker status in the same combat, it will not trigger attack triggers again
