When a combat has both a 'when I attack' and a 'when I defend' trigger, which trigger goes on the chain first and which resolves last?

Ruling: Attacker triggers go on the chain first, then players who are neither attacker nor defender, then defender triggers. Since the chain resolves first-in-last-out, defender triggers resolve first.

Sequence:

• Attacker adds their triggers to the chain
• Players who are neither attacker nor defender add their triggers
• Defender adds their triggers to the chain
• Chain resolves in reverse order (defender triggers resolve first, attacker triggers resolve last)
