The goal of this Festival of Legends Wild Hearthstone Exodia Mage OTK combo deck is to use Audio Splitter combined with Rewind!

We do this by playing Thaddius on the even polarity, Haleh Matron Protectorate, Umbra, Sorcerer's Apprentice, Molten Reflection on Umbra, Audio Splitter, Rewind for Molten Reflection to copy Audio Splitter, Rewind for Brain Freeze to destroy Audio Splitter, and then we repeat that sequence infinitely!

Super fun meme deck! Good luck!
