I am unsure of the origin for most of these promos although I’ve heard some theories (you can ask me if you want to hear some of them). The Chaosgallantmon seems the easiest of the five to get. The Dorumon card for sure came with the Digimon World 4 game. Supposedly, the Omnimon is the hardest card to get and many collectors weren’t even sure it existed for a long time. The Goldramon may be just as rare. If you have more information on any of these, I’d love to hear it.
