Which Displays to get for an advent calendar?

Hello everyone :)

Me and my BF are big Digimon Fans and new to the card game. We have 2 premade decs and one world convergence display. I figired it would be a pretty fun advent calendar with 24/48 booster packs in them. What displays/ boosters would you recommend? We honestly just love dope card designs and play around with deck building, but don't really know everything yet.

Thanks in advance! (English is not my native language)
