I made math birb cards. The suits are rose curve, knots, complete graphs and dihedral groups.

@fractalkitty the four of knots is unknotted! (I blame the nuthatches)
@jsiehler Good catch! I will blame the knot-hatches too! They are so devious. We may have to call it the wild card. I already ordered some decks - they can be the original knotty knot-hatches. I think with some of the perfectionists out there I should upload the fix - what do you think? I appreciate the find - thank you. I went through these so many times and missed it!
