Umm... Anti-Arrest tech? I can't really think of a reason to main deck this card and even a sideboard slot would difficult to make a case for. However, I do have to give it credit since there aren't many cards that have repeatable enchantment destruction (including repeatable permanent destruction, I could only find 7 other cards). Still, this card can only target Auras on your own creatures, so it can't deal with Slippery Bogle decks. But, if you need a way to blow up Auras on your own creatures, you'd be hard-pressed to find a better way to do it. Except for Devout Harpist, which is strictly better in every way.
Pros: Repeatable Aura destruction
Cons: Only hits your own creatures
Replacement: Devout Harpist
