Why is this my favorite

I think @decoypalmette nailed it with their answer but Im just going to add this as well I think Yugioh has a problem with bringing in new players/collectors

If you collect all 20 cards from a certain deck, you will be able to use that deck at any time

As stated before, it is one of the most options per mana you can get from a card

Just because Konami makes cards that can nullify costs, cards like Judgment Dragon, and other things that aren't exactly stellar design doesn't mean it's automatically ok to do so yourself

He also helps you keep cards in your hand, allowing you to get a card whenever you ink one
