Each player brings a deck to the tournament which they believe is challenging to win with. Each round of the tournament, opponents temporarily swap decks for that match, and try to win the round with the deck their opponent brought.


All decks are useful in some way, and this variant provides a fun opportunity for a player to dust off their more challenging decks and give them some use in tournament play.
