If one thing is true of Magic: The Gathering, it's that the players can be very vocal if they don't like a particular deck or strategy. One strategy that gets a lot of negative attention is Mill. Whether it's Commander, kitchen table casual, or Modern, people don't like seeing their cards go into their graveyards. From the more innocuous mill decks like UB Mill to the titan of obnoxious milling Lantern Control, decks that mill opponents' cards get under players' skin.
