Ouch, returning a Province is expensive! Followers is nice, but it's not worth $8 with a Treasure Map problem.
You can also gain a Duchy, which potentially eases the sting of the Province return, but I'm not sure if it's enough. Trashing the Province obviously isn't an option as it shortens the game too much.
I want Tournament to require Duchies (thus forcing a semi-choice between Duchy rushing and going for Provinces), but that also makes the gain-a-Duchy clause stupid. What if Tournament required a novel Victory card that accompanies it in the Supply? What if that card became cheaper as copies of it are gained, so as to reduce the purchase luck component?
Tournament III - $4 Action
+1 Action
Each player may reveal a Field from his hand. If you do, trash it and gain a Prize (from the Prize pile) and/or a Duchy, putting them on top of your deck in any order. If no-one else does, +1 Card +1 Coin.
Setup: Add the Field pile to the Supply.-----------------------------
Field - $8* Victory
3 VP
When you gain this, place a Field token on top of the Field Supply pile.
This costs 1 Coin less per Field token on the Field Supply pile.Field is a bit of an oddity in that it becomes strictly better than Duchy once three have been bought. I am, however, not convinced this is a bad thing. Also, the wording is designed such that the value of the card universally declines; that is, if four Fields have been gained, it is worth $4 for Remodel-type purposes.
I also briefly considered a version that can gain Provinces (and returns to an OR clause instead of AND/OR), but I don't like it as much.
