About a week or two ago, I realized that it is possible to build a deck in the digimon card game that is 100% beetle themed. So yesterday I pulled up TCGPlayer so I only see the English released cards and went through every released insectoid digimon to do my best to figure out which ones are beetles. With just the Digimon Monster cards, I was able to build a 37 card deck, which could have been full size if I didn't limit myself on some so I could also put Options and Tamers in. You can see the deck pictured above, but I have included the list below.
