Favorite card?

Hey everyone, first time poster here. What's your favorite card in your collection? Could be something powerful or could be something that you're just nostalgic or sentimental for. I think my favorite card in my collection is this Gold Rare DM with the classic Yugi Starter Deck art. It's just the right amount of flash for me without being over-the-top, and I like the gold border around Dark Magician.
