down where i play and i guess at uk nationals we play best out of 3 games. is a best out of 3 game classified in the rules as a match. also i have also checked in the rulebook that if any card is sent to lost zone it stays there till the end of the match. so if any card was sent to the lost zone the match is a best out of 3 games so the cards would not return to the deck intil the round is done.
