Azathoth, Blind Idiot God

When Azathoth enters the battlefield, your opponent gets two artifacts named Maddening Drum and Accursed Flute. If both artifacts leave the battlefield, Azathoth becomes a creature and gains protection from everything.
When Azathoth becomes a creature, exile all other creatures, exile all players hands, exile all players graveyards, and each player exiles the top card of their library until there are five cards in their library.
