Enters the battlefield

Enters, or 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. 
==History==
"Enters the Battlefield" was originally phrased as "Comes into play" (abbreviated as CIP)
"Enters-the-battlefield" abilities were introduced as 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. Popular cards with "enters-the-battlefield" effects were <c>Nekrataal</c> and <c>Man-o'-War</c>. "Enters-the-battlefield" abilities which damage or kill a creature or destroy a permanent were colloquially known as 187 effects. 
"Enters the battlefield" replaced the term "comes into play" when Magic 2010 rules changes went into effect. Starting with Bloomburrow in 2024, the phrase "Enters the battlefield" was shortened to "Enters", with cards receiving errata in Oracle. Entering will be connected specifically with the battlefield, so cards won't be worded as “enter the graveyard” or "entering the library". R&D will occasionally write out “enters the battlefield” where they think it is needed for clarity in a template. Sagas, which already used the "enters" template in their reminder text, showed that players could comprehend the change conceptually. In contrast, “Leaves the battlefield” is not being shortened to “leaves” as R&D have used leave as a means to talk about cards leaving the graveyard, so it created ambiguity they didn’t want.
Despite being shortened, "Enters" is not a keyword. R&D have talked about keywording the action multiple times. The word "arrives" was considered as an alternative. To date, the cost of changing the language has not been deemed worth the change.
