This charming loop transforms a furry army into a self-sustaining mana engine, fueled entirely by the overlapping strengths of your permanents. With The Fire Crystal granting your creatures haste, the newly spawned tokens don't have to wait around to tap for mana. Instead, Song of Freyalise steps in to give every single one of those creatures the ability to tap for any color, letting you easily fund the massive mana cost required to activate The Unbeatable Squirrel Girl's exponential token-making ability over and over again.
