I was 8/9 when in 2002/2003 when my parents bought the 4 startes decks (Yugi, Kaiba, Joey, Pegasus) and i played for years with those cards. Now, almost 20 years after, these are the only cards i have left. I know this is not a real playable, too many monsters, few spell and traps, but if you want go back in time and feel like that child again, you can use this deck, you will enjoy it. This is a travel in time, not only a deck, it's also a true story.
EDIT: I decided to add a "side deck" removing the worst 10 monsters and balance the deck the best i can. Now it's 40 cards in main and 10 in side which is still part of the deck. This new version is a lot better to play with.
