When Ahri, Nine Tailed Fox's ability triggers against units attacking from Trifarian War Camp, does Ahri reduce their Might before or after War Camp's buff applies?

Ruling: Trifarian War Camp's passive applies first, giving attacking units +1 Might before Ahri's ability triggers. Ahri then reduces the buffed units' Might by 1.

Sequence:

• Units move to the battlefield and are designated as attackers
• Trifarian War Camp's passive immediately applies, increasing their Might (e.g., 1 Might becomes 2 Might)
• Ahri's ability triggers on the attacking units, reducing their Might by 1 (e.g., 2 Might becomes 1 Might)

Nuances:

• War Camp is a passive effect that applies before triggered abilities like Ahri's
• Ahri's ability specifically deals with attacking units, so it triggers after units are designated as attackers at the battlefield
