Sanc06, Twins17, Akasha03, Sakujo13, and Innocence03
But because I missed two weeks of weekly games, I'm adding something extra to this as well! If you have the following card, Mural11 then you will get a gold cert. This card does not count as a match with the others, so if you have for example Twins17 and Mural11 that will still only be counted as one.
Here are the prizes for the number of matches.
1 match = 1 random card
2 matches = 3 random cards and 1 star
3 matches = 3 random cards, a Bronze cert and 1 star
4 matches = 4 random cards, a Bronze cert and 1 star
5 matches = 4 random cards, a Silver cert and 1 star
Good luck! Remember that cards pending in the cert exchange are not counted as having the card.
