Just a quick comment.....I got 4 reward codes from winning the Champs League and got to choose 3 marks/nymphs. I choose a fire mark 1st, then an earth mark, then a light mark. but once I looked into my bazzar area it showed i had 2 earth marks and 1 light mark.
This might be a bug or maybe you have to not input the codes back to back like that without looking at your deck.
