YuGiHo, MTG, Pokemon cards, Labubu, etc basically

ANYTHING that comes

• sealed (as opposed to transparent packaging) and is
• collectible (limited supplied of some specific items)

physical or not is prone to betting and thus addiction. We tend to ignore the thing we care about, because we are passionate or come up with explanations (not to say excuses or post-rationalization) but in practice it doesn't matter if your MTG deck is super "powerful" or that you see yourself as a great strategist, in fine if you do buy or promote those your are promoting gambling.
