I grew up in the 90s and was lucky enough to find a few of the cards I had as a child, so I collect a little bit of both, but depending on what you are into as well as your budget, you may want to choose one over the other

That card starts the game outside of your deck, in your sideboard, and doesnt count towards your decks minimum size
