Rule 407.1
Official source text from the 1 May 2014 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).
