Konami revealed a new expansion coming to the Yu-Gi-Oh! trading card game in 2020 as we're getting Legendary Duelists: Magical Hero. This 56-card set will feature Yugi's Dark Magician and Dark Magician Girl together in a team-up. Altogether you're going to be getting 29 Commons, 10 Rares, 8 Super Rares, and 9 Ultra Rares. The set will be released on January 17th, 2020 and be sold for $2 per pack. You can read more about the set below from the official Yu-Gi-Oh! press release.
Many Spell and Trap cards have featured the duo together in their art, but for the first time ever Dark Magician and Dark Magician Girl will be able to battle alongside one another as a single Fusion Monster: The Dark Magicians! Together, they excel in both might and magic, with 2800 ATK and the ability to draw a card when a Spell or Trap is activated. Draw another Spell or Trap and you can Set it directly to the field and activate it that same turn if it's a card you can normally use at that time – even if it's your opponent's turn! Even though it's a Fusion Monster, destroying this one card doesn't defeat both Dark Magician and Dark Magician Girl at the same time – you'll get to Special Summon both of them to the field from your hand, Deck, or Graveyard!
The Heart of the Cards allows Yugi to get the cards he needs to Summon Dark Magician and Dark Magician Girl at will, but you might want a card that guarantees you can Summon them when you need them too! Magicians' Souls is a new effect monster that can be used from your hand to send a Dark Magician or Dark Magician Girl from your Deck to the Graveyard, then Summon it back to the field. Once you have one of the two masters of magic on the field, Magicians' Combination is a new Trap Card that lets you Tribute your on-field Dark Magician or Dark Magician Girl to Special Summon the other one from your hand or Graveyard and negate any card effect your opponent activates!
