When it comes to starting a Digimon trading card game collection, the question of how many starter decks you need can be tricky. After all, each starter deck contains 60 cards and you probably don"t want dozens of copies of the same card in your collection.
To start off with, we'd recommend just one or two basic starter decks, depending on how serious you are about collecting. If you want to play competitively, then a few more may be necessary for different combinations and strategies.
However, if you're mostly in it for the artwork and the fun, then there's no need to go over the top unless you get that collector's itch!
