I would like to start collecting a set with all of the really colorful cards with the big Japanese text across the picture, however I dont know how to search them all.. is there a name to these kind of cards so I could look up which ones I still need to collect? I feel like I keep randomly stumbling on more of them I didnt know existed and I want to get a surefire checklist that I can start working on. For reference, the cards im talking about have Mega Lucario, Mega Diancie, the charizard is one.. I think theres a mega Gardevior.. any help would be appreciated!

TIA
