Mastermind of the Underworld

Xanathar, Guild Kingpin holds court in the shadows, embodying the cunning and control that define the underbelly of the Forgotten Realms. This legendary Beholder doesn’t just dominate the battlefield with a solid 5/6 presence but fundamentally alters the flow of your opponent’s resources. Each upkeep presents a tactical choice: pick an opponent and lock down their ability to cast spells for the turn, while granting you unparalleled insights into their deck’s top card. This control shifts the typical tempo game by letting you run interference against opponents’ plans while simultaneously expanding your card options with the freedom to cast their top card using mana of any color.

Its synergy with cards that manipulate libraries or capitalize on casting spells from unusual zones—such as Narset, Parter of Veils or Jace, Wielder of Mysteries—makes Xanathar a versatile cornerstone in blue-black control or midrange decks. The extended art foil treatment captures the eerie charisma of this notorious crime lord, emphasizing its mythic stature. For players who value strategic disruption combined with resource advantage, Xanathar becomes a pivotal piece in any Adventures in the Forgotten Realms lineup.
