When Ahri, Inquisitive attacks and Master Yi defends, does Ahri's -2/-2 effect resolve after Yi's +2/+2 from defending?

Ruling: Master Yi's +2/+2 from Wuju Bladesman is a passive effect that applies immediately and cannot be reacted to. Ahri's -2/-2 trigger goes on the stack after, with the attacker having first focus and priority.

Sequence:

• Yi gets +2/+2 immediately (passive effect, does not use stack)
• Ahri's -2/-2 trigger goes on the stack
• Attacker has first focus and priority to respond

Nuances:

• Attacker triggers go on stack first, then defender triggers, but passive effects like Wuju Bladesman don't use the stack at all
• This assumes Yi is defending alone
