Thats not to say that you wont find powerful cards in a Set Booster indeed, each pack of 12 cards (plus two bonus, non-game cards such as art cards) contains 1-5 cards at the Rare or higher rarity level, making them a more appealing product in some ways than, say, Draft Boosters
PokeDude is very obscure but is super hard to find so it racks up quite a bit of value like that
It'll be appealing to people who just want to open cards, have a collection with their favorite Pokemon to look at on the go, and maybe learn how to battle now and then. A Yu-Gi-Oh player from my Pokemon League, Griffin S., also agreed the accessibility is what makes Duel Links so successful
Every booster pack contains a card from a bonus sheet, select cards originally printed with the modern Magic frame now returning with what we're calling the retro frame treatment
