Madgod's Rage

Destroy all white permanents. If you control a creature named "Jyggalag, Prince of Order" Pay {w}{w}{w}{w} instead of paying Madgod's Rage's
mana cost. If you do, gain control of those permanents instead.
When Jyggalag became Sheogorath, he had the grand library he had built destroyed. The madgod in a rage said that decisions mortals make are impossible to predict.
