Quote From: WhitePhoenixHello,
I am doing research for a CardDex and inventory tracker. I am having difficulty finding accurate information about the VS cards. The only two sources that I normally use, Bulbapedia and Serebii, have incomplete or inaccurate information. I know it has been a long time since these cards were published, but if anyone remembers how the cards were packaged, please contact me.
The information that I have so far is that the cards came in packs of 30. There were 3 half-decks with randomized cards(?) but only one type of pokémon (the example given states the Fire-Water half deck only had Fire pokémon cards), but the other packs had random cards. There is no real information about whether these packs consisted of completely random cards or if they contained a certain percentage of pokémon, trainer and energy cards. The only half-deck that had fixed cards was the promotional Tyranitar Half Deck.
Any accurate information (or even a link) will be greatly appreciated.
You'll be hard pressed to find any information about them these days. Perhaps checking around archive.org around the time they were released and see if the official pokemon website and WOTC(?), i think at that time, have any information on it.
