Unravel the Aether

Commander is where Unravel the Aether earns its slot, specifically because the shuffle clause shuts off graveyard-based recursion loops that dominate the format — enchantments like Animate Dead and artifacts like Skullclamp don't get to sit in a yard waiting to come back. In competitive mana bases packed with artifact and enchantment utility permanents, two mana at instant speed answers almost anything. Outside Commander, Unravel the Aether sees essentially no play — Modern, Pioneer, and Legacy all have faster, cheaper, or more flexible options, and the anti-recursion angle matters far less in those formats where graveyards are easier to police through other means.
