This card set was offered to participants in the Mark of Heroes organized play program. Cards were delivered through the D&D Rewards program and were mailed to recipients. Cards could be "played", as noted on the card itself, to gain some advantage in the organized play program.
The set of ten cards included:
Shaper of the Soul Mist
Right Scroll for the Job
Pride of Breland
N.B. Set 1 also included a Missed Me! card; the Set 4 card can be distinguished by the absence of the exclamation point.
