I'm going to describe a problem I had in a game of universalis. What I want to know is, Did I misunderstand the rules.
We had a master component of a barbarian, who had (relevant) traits of "mighty thews", "trained warrior", and "furry underwear", all of which were deemed appropriate for a physical brawl. This brawl took place inside the barbarian village, meaning that introducing new barbarians was a reasonable option.
A player realized that for every 1 coin spent on introducing a barbarian, he would get three dice for the ensuing complication. Because of the way complications work, he would then get back triple the coins (if he lost,) or be very likely to at least recoup his investment.
This led to a horrible situation where the best solution was to go all-in on generic instances of any master component with more than one relevant trait.
It seems to me that I must have missed some aspect of the rules that disallows this, but I couldn't find it.
Of course, I can always buy a tenet of "no thundering herds", or make sure that all my complications are set in limited-space environments, so that people can't bring in infinite generics. It's easy to fix the problem, but I can't help feeling that I've just missed something that stops this up front.
