Even if you lost you still get high ammount of exp compare to other easy challenge
I'm currently trading the opening card 1 hand challenge with 3 people. I'm looking forward to trade with more. Send the challenge, and I'll send back! I'm on very often, so we can duel as well.
when vagabond ask you to intoduced him to your friend, just pick a challenge (1 hand) and select one of your friend.
Or when vagabond come to your duel world by your friend recommendation, after the duel, when he ask to introduced to your friend, just select the same player whom send you the vagabond. :)
