MTG Salvation

I need some help with the way DTAs work. What happens if you control a Golgari Thug and attack with Vaevictis Asmadi, choosing to sacrifice the Thug. Will the Thug's trigger resolve first or will the DTA after everyone fulfills the requirement of sacrificing their permanent trigger first?

I assume that Asmadi's trigger resolves first, but just checking because it's a super neat interaction if Thug resolves first.

Wonder can be a win condition in my Sidisi, Brood Tyrant self-mill deck, although obviously I have a lot of ways to get it in my yard.
