I just tested it and it's definitely a bug. I made this game long ago but I don't think many experimented with the wannabe class haha.
Glad you enjoyed the other bits of the game!

similar bug, I played consulter with the exact same setup, but only ever drew the one muscle card.
edit: after trying it multiple more times, it seems like it's almost random? sometimes I get muscle, sometimes I get one of the consulter cards, and sometimes its just the neutral deck with no extra cards
