Hm, I've noticed that the core rule book doesn't state any sort of mulligan rules in the game and we've been playing without them for a while. But it seems that the rules do exists and they're hidden away in the FAQ, which seems like something that nobody would happen upon unless curious... This seems like rather iffy organization, is there a chance we could get a comprehensive rule book?

I forget who was working on this ....Manitou ? or Jhaelen ? - one of the Forum members was trying to form something like that.

And I agree...in the immortal words of Jhaelen, "The game is utterly unplayable without the FAQ"

Sad, but true.

Just look at the FAQ :

(v1.1) Mulligan
Players are allowed to mulligan their starting hand once. A mulligan allows for
each player to shuffle his starting hand into his deck and draw a new starting
hand. The player must keep his second hand if he chooses to take a mulligan.
