Dice over a flimsy cardboard deckbox is a HUGE step up. A bit sad they're probably going to be the boring new numbered ones that I am still salty about, but still, I'd much rather something useful over a small cardboard box I can't really put much into.
Perhaps though, these decks could include maybe 2 of a meta-relevant GX and then one of like, a staple support-type card or something. Depending on what they mean by "promos", either they're going to be new (variant of a) card we haven't gotten yet, or it's just a straight reprint.
