I didn't get the free deck

I started a new account in american server, I completed all the starter quests, unlocked all heroes, but I didn’t get to choose one of the free decks. I don’t know if it is a bug or something.

What quests do you still have? There are multiple parts to the starter quests

did you get to rank 25?
