I'm fortunate that I kept all my old cards, except for a handful that I know I'm missing. My problem is that I can't find anyone to play against. Any friends I have around me that like Pokemon don't play the TCG and have no interest in it, so I'm also left with only the GBC game to play.I wish I had enough real cards (as in not just on the GBC) to make a useful first generation deck with, but I don't have enough duplicates of the useful cards and they're really hard to find nowadays. All I can do is make an okay-ish fourth generation deck I use to duel a friend with occasionally. His decks aren't super strong either, giving a fair match.
