Okay, you can't open with both tournament and rebuild, but if you open tournament/silver and use your first two turns at five or better to buy rebuilds, all your four turns to buy tournament, and anything less than four to buy either cantrips or nothing at all, you can hit the prizes really fast and have a running start at the provinces that will be over probably before you even get to use some of the prizes.
I have no simulator data or anything, but this seems like a good overall concept. As always, it depends on what else is out there, but if tournament is the obvious choice and the prizes will matter, I think getting two rebuilds as early as possible is a good idea.
