Great explanation! I think this rule is missing from the video, so mentioning it in case everyone is learning from it: Haggis & Tatties and Haggis & Neeps are only meant to be played with the "scoring variant", where each captured card is worth 1 point.
I am not a big stickler for card quality, so I may not be the best judge for this. However, I think the quality is quite nice. The cards are 350gsm, IIRC. They have a smooth finish and feel to them.
