I just ran a story encounters tournament yesterday to encourage this as well. I hand wrote the strategies with the metagame in mind (who the good players were, who the new players were, what masters are good against each other, etc.) and predetermined the matchups before hand.
The strategies weren't 100% balanced, as I obviously didn't have any time or opportunity to play test them, but I think it went pretty well.
1st place game was between McMourning and Leveticus, with Leveticus winning.
2nd place was Nicodem v. Lilith, Lilith won.
3rd place was Pandora v. Sonnia, Sonnia won.
I stacked the odds against the best players and they still came out on top. Leveticus had to die 8 times for half of one strategy (2 VP) and ended up dying an unprecedented 11 times in one game.
(Edit: for those wondering how this is possible, he just looks at the top cards of his deck and stacks the odds, I figured getting to turn 9 would be tough, and of course he has to not actually die, and it turns out he got to turn 12)
Also I like the idea of you changing the things that you did, just to see how it goes. I think local tournaments are a great laboratory to try things out. Post up the results, it might even help out the devs...
