Silent Magician (サイレント・マジシャン Sairento Majishan in Japan, written as 沈黙の魔術師 Sairento no Majishan in the Japanese anime) is a series of Spellcaster-Type "LV" monsters.
In the TCG and OCG, there are 2 members: "Silent Magician LV4" and "Silent Magician LV8". They were first released as Yu-Gi-Oh! Nightmare Troubadour promotional cards.
In the anime and manga, the single card "Silent Magician LV0" (simply called "Silent Magician" in the manga) was used by Yugi Muto, which gains LVs with its own effect.
