Hi....in this game exist the mulligan rule....if does... could any body explain me how it works????

Tournament rules can be found HERE.

The mulligan rule is on page 2:

"Before each game begins, and before any setup cards are placed, a player may, for any reason, re-shuffle his or her opening hand into his or her deck, pass the deck back to his or her opponent for additional shuffling or cutting, and draw a new setup hand from the same deck. This may only be performed once per game."

Thanks a lot.....
