I have tried to get a couple of achievements through the starter deck duel events. I tried to get the "Taking you with me" achievement (where you have to win on the same turn you sacrifice 6 or more permenants) by casting Lich-Knights' Conquest in the golgari snack time deck. I have done this achievement twice. Both times the opponent did not surrender so I know the spell resolved and I killed them on the same turn. At first I thought the achievements might not be connected to the stater deck duel event, but I noticed I made progress toward the lifegain achievement with the same golgari deck through food.
