Actually you can. I just did. Go to the market to buy the structure deck area. Click in the i-info symbol and a bingo card comes up. I played it and bam. Now i have fields of the warriors, which by the way i would not have, if the anonymous guy above wasn't so kind as to offer help.
I'm gonna help a lot of you out. You can still get this ability. If you already have Joey you can go into the Legendary Warriors structure deck and click the info button. It gave me the ability even though I didn't even create the account when the event happened.
