The fun part is that a lot of trading cards have their roots in the early movements for cigarettes. Same idea for the most part, except it was typical for pinups instead of monsters or magic. You bought tobacco to get the cards, so tobacco became popular amongst kids. If you wanted to collect em all, you would buy more boxes of cigarettes, so imo it's even more of a parallel than just calling out TCGs

The fact that the idea swapped to hooking kids on gambling is honestly a no brainer, especially since the cards were the things helping sell the cigs anyhow.
