This monster is based on Cao Cao (courtesy name: Mengde), from the historical novel Romance of the Three Kingdoms, founder and emperor of Wei state during the Three Kingdoms Period, being best known as a great adminstrator and his military conquest. His moniker "Ambitious" refers to his frequent protrayal as a ruthless tyrant in multiple adaptations.
This monster's phoenix motif might be referencing the Vermillion Bird, one of the Four Symbols that corresponds to the Fire Element. This is fitting, as it symbolize leadership and nobility, fitting with Cao Cao's upbringing.
This card's second effect to summon any monster it destroyed in battle is a reference to Cao Cao's habit of recruiting his former enemies as subordinates, usually those with great skills.
