I would open Wishing Well, Iron Works, gain a few tournaments with IW and then when Provinces come into play, gain Wishing Wells off the IW. I would not buy Silver at all this game. On $5-$7, I would buy some labs. No need for golds. When I felt my draw was good, I would also throw in an Outpost, and all at the same time, I would be trying to win tournaments first getting princess for the +buy and then Followers for the attack. If I saw my opponent was going for a heavy feodum strategy, I would potentially get Trusty Steed prior to Followers and Princess just for denial, however, that would depend on how many tournaments/Provinces they had and how clogged their deck was.
Anyway, a good Tournament strategy should kill any feodum strategy on this board...except maybe trusty steed/feodum which to me still doesn't sound good.
