Battlefield

The battlefield, formerly known as the "in-play zone", and even earlier the player's "territory", is a shared game zone.
==Description==
Permanents reside on the battlefield after being put there, usually after being cast (for artifacts, creatures, enchantments, and planeswalkers) or played (for lands). Instants and sorceries can't enter the battlefield; those cards are usually put into an owner's graveyard as the last part of such spells resolving.
Prior to the Magic 2010 rules changes, many cards used phrases such as "when [this] comes into play", CIP, "put [something] into play", and so forth. As a result of the changes, cards that referred to something coming into or leaving play were given errata to refer to the battlefield instead.
===Piles and sectors===
Some cards divide cards on the battlefield in piles (<c>Camouflage</c> and ), or the total battlefield in sectors (<c>Space Beleren</c>).
==Rules==
===Obsolete terminology===
==Rulings==
*When a permanent spell resolves, it is put onto the battlefield as a permanent.
*When a land is played, it is put onto the battlefield as a permanent. 
*Tokens only exist on the battlefield.
==MTG Arena==
The themed playing field on MTG Arena is also called a "battlefield". Each new set comes with a themed field that usually has a unique soundtrack and a small amount of clickable interactables.
