Thanks! I knew that in my senerio I was dead but I wasn't exactly sure I had all of the mechanic worked out.
What does the stack look like?

Nothing will be on the stack, as you will die before the Angel triggers even get put there.

Interesting. I never even thought of checking the game status before the Angel triggered.
The Angel actually did already trigger, when the damage was dealt.
However, triggers can't go on the stack until a player would recieve priority.
Before this happens, state-based effects are checked. So, while the angel did trigger, the game ends before the trigger is placed on the stack.
