Rule 407.1
Official source text from the 27 September 2013 Rules release
Earlier versions of the _Magic_ rules included an ante rule as a way of playing "for keeps." Playing _Magic_ games for ante is now considered an optional variation on the game, and it's allowed only where it's not forbidden by law or by other rules. Playing for ante is strictly forbidden under the _Magic: The Gathering_ Tournament Rules (Wizards.com/WPN/Events/Rules.aspx).
