My personal guide:
Turn 1: Get Skateboarder, Blacksmith, or the 5 costs, if none are available then die.
Turn 2: Still buy available 5 costs unless you need money for Skateboarder or Blacksmith
Turn 3/4: If you have Assassin in shop and have money; then get him. If not continue turn 2
Turn 5: You should have Skateboarder/Blacksmith, Blacksmith/Assassin and Chef/Guitarist. If you have available capital then get Boxer.
Turns 6-8: Make sure you have Skateboarder, Blacksmith, Assassin, and Boxer.
Turn 9: PRAY
Turn 10: Get Bodybuilder
Turns 11-14: Wait
Turn 15: Get Bouncer (Edit: Instead, replace Boxer and Blacksmith with Guitarist, Goon, and Mall Cop).
Turns 16-???: Wait for inevitable death
Thank you for reading my guide.
