* Deck Leaders are Specific: In Duel Links, each character has a pre-determined deck leader. This is usually a character-specific card that represents their archetype or style.
* Dark Magician isn't a Character: While Dark Magician is a popular and iconic card, it's not tied to a specific Duelist in the game. Therefore, it can't be a deck leader.
However, you can build a powerful Dark Magician deck in Duel Links:
* Many Strong Cards: Duel Links has plenty of powerful Dark Magician support cards, including "Dark Magician Girl," "Magician of Faith," "Dark Magical Circle," and more.
* Deck Building Options: You can create a deck focused on summoning Dark Magician and using its effects. You can even include other popular cards that complement the strategy, like "Cyber Dragon" or "Blue-Eyes White Dragon."
So, while you can't make Dark Magician your "leader" in the game, you can definitely build a fun and competitive deck around him!
