Tick-Tock Man

As an alternative to the outright ban on certain masters, what if instead of the ban step there's a step where both players propose masters. During this step each player says that they will play one of two masters, followed by list building as usual. This would allow for people to be encouraged to run different lists, but allow them to use the shiny show pieces they've been working on. Using the reconnoiter example(keeping in mind I don't really have any experience with or against arcanists), you would obviously put Ramos up as one of your masters, but maybe you put up Marcus as your other master. Now you've put your opponent in a situation where they can build a list full of anti-Ramos tech at the risk of being at a disadvantage against beasts. That being said, I don't think I'm much of a tournament guy so at the end of the day it's not going to come up much for me.

I have been asked to run a couple of demos for Malifaux at an event on August 10th, less than a week before the release at Gencon. The conundrum I face here is I'm not sure whether to run with the 1.5 rule set knowing that they're going to be replaced right away, or should I print out some of the 2.0 cards and run them knowing they're likely to have changes to them by release. Any suggestions will be very helpful.
