>>56279439ex/v/tag team cards sell better I guess because they're inherently rarer from packs. if one of the best decks was just regular uncommons they wouldn't sell as many packs
it's why regular legendary cards are basically always packfiller, they're just there because omg they're legendary so kids end up being hyped they pulled a dialga
honestly for how much pack filler % pokemon has to other TCG, it's surprising we don't have any other formats around for it. there's such a strict cut off line between viable and not here due to it
