  • Good but some shows are colts (etc.) fan boy shows

    It’s not my podcast so can do what you want as publisher but some shows are just way too focused on colts. Football card podcast is like a bears colts show that gets tiresome. And really the explicit language is not really needed. Immaturity maybe.

  • Good pod but needs diversity

    Lots of good insightful card talk, but leans too heavily into Colts and WNBA. I understand that it’s the way you hobby, but as someone that doesn’t care about either it can be a drag. Shows how good it is though considering I’ve stuck through it despite the lack of connection I have to those spaces.
