Do On Attack triggers all resolve before On Defend triggers start a chain?

Ruling: "When I attack" and "when I defend" triggers all go on one chain together. Attack triggers are put on the chain first, which means defend triggers will resolve first.

Sequence:

• Attack triggers are placed on the chain first
• Defend triggers are placed on the chain second
• The chain resolves in reverse order (defend triggers resolve first, then attack triggers)
