|To Start: Speak to Poe Tatters in Sanctuary.
Poe Tatters says,"If you're going to be a serious card duelist, find Sam Potts.
I believe she was last seen at the tournament board in Sanctuary. "
Now that you've gotten a little more practice under your belt, find Sam Potts to teach you more.
This is a Search quest. This quest will advance the Card Duelist job.
