oracle:"Enters the Battlefield"

Enters the battlefield refers to putting a permanent onto the battlefield, or to an ability which is triggered when a permanent is put onto the battlefield. It is commonly abbreviated ETB.


"Enters-the-battlefield" abilities are a mechanic designed by Bill Rose for Portal. The design team liked it so much that they included it on one card of each color in Visions.[1] Popular cards with "enters-the-battlefield" effects were Nekrataal and Man-o'-War.[2]

"Enters the battlefield" replaced the term "comes into play" when Magic 2010 rules changes went into effect.[3]

"Enters-the-battlefield" abilities which damage or kill a creature or destroy a permanent were colloquially known as 187 effects.

  • 603.6a Enters-the-battlefield abilities trigger when a permanent enters the battlefield. These are written, “When [this object] enters the battlefield, . . . “ or “Whenever a [type] enters the battlefield, . . .” Each time an event puts one or more permanents onto the battlefield, all permanents on the battlefield (including the newcomers) are checked for any enters-the-battlefield triggers that match the event.
