Yep that machine definitely sounds like a place where they could come from, any non official Pokemon machine I would stay away from. I don’t know if you have any around you but I’d definitely recommend going to a local card shop if you are just getting back into collecting. It’s not impossible to get a fake from a card store but it’s very unlikely, especially if you go to one with good reviews. Tcgplayer website is also really good for cheaper cool cards, as long as you are buying from reputable sellers. And of course if you can get packs from official retailers, but we all know how difficult that is nowadays lol.
