Congratulations Abdulla for getting
third place in your first tournament!
(Most of the players there were even using upgraded cards and here you are so new.) I'm so proud of your accomplishment.
I recommend you think carefully how you'd like to spend your $ 4000 electrum. Maybe a certain card in one of your decks is very important to upgrade, but if you enjoy tournaments, perhaps getting regular cards to make some more great decks might be more important. Also remember, that if you upgrade a rare that you don't have more of, it wouldn't be able to be played in most of the tournaments. So be especially careful upgrading those.
Again, congratulations!
Janice
