Didn't see anything exceptionally unlucky in your draws really, you even had a few collisions early on your chapel/explorer. It seems like a reasonable strategy that mitigates some of the issues with chapel in province games where when you start greening your deck chokes. For a 5/2 start I think it was a good opening, I don't see anything better in the kingdom really for the opening. He probably had a better shot if he opened swindler instead of silver though.
EDIT: Sorry meant didn't see anything exceptionally lucky in your draws (since you mentioned feeling lucky, I didn't really see it)
