The magic here hinges on Song of Freyalise’s first two lore chapters, which temporarily transform your entire board into mana-dignitaries capable of tapping for any color. Once your creatures can effortlessly bank this mana, Aggravated Assault steps in to convert those funds into an endless sequence of untap steps and extra combat phases. Because Aggravated Assault untaps all your creatures as part of its resolution, Song of Freyalise's granted mana ability resets immediately, allowing you to repeat the loop indefinitely to generate infinite colored mana and infinite attacks.
