Tasha's Hideous Laughter (AFR)

Sorcery

Each opponent exiles cards from the top of their library until that player has exiled cards with total mana value 20 or greater.

Staple mill finisher for blue tempo and control decks. Tasha's Hideous Laughter is one of the most efficient ways to close out games in formats where milling is viable—it exiles roughly half an opponent's deck in a single spell, and the mana value threshold makes it nearly impossible to dodge. A four-mana instant that functions as a win condition in Modern and Pioneer mill strategies, and a powerful tempo tool in Commander control shells. Essential for any deck built around milling opponents out.
