The Commander format is all about picking your hero and building a deck around them. In this casual, multiplayer format, you choose a legendary creature to serve as your commander and build the rest of your deck around their color identity and unique abilities. Players are only allowed one of each card in their deck, with the exception of basic lands, but they can use cards from throughout Magic's history.
A card's color identity can come from any part of that card, including its casting cost and any mana symbols in its text. Every card in your Commander deck must only use mana symbols that also appear on your commander. Colorless cards are allowed as well.
This is where your commander resides during the game when they are not in play. At the start of the game, each player puts their commander face up into the command zone. A commander can be cast from the command zone for its normal costs, plus an additional two mana for each previous time it's been cast from the command zone this game. If your commander would be put into your library, hand, graveyard or exile from anywhere, you may return it to your command zone instead.
A player that's been dealt 21 or more combat damage by the same commander over the course of the game loses the game. The commander is tracked across zone changes for this purpose (for example, if one player takes control of another player's commander, any damage that commander already dealt is still counted).
Each player starts with 40 life, places their commander face-up in their command zone, and draws a hand of seven cards. Players are seated randomly in a circle and turns progress one player at a time in clockwise order around the table.
Commander is also a generic term for an officer commanding any armed forces unit, for example "platoon commander", "brigade commander" and "squadron commander". In the police, terms such as "borough commander" and "incident commander" are used.
Commander is a rank used in navies, but is very rarely used as a rank in armies. In most armies, the term "commander" is used as a job title. For example, in the US Army, an officer with the rank of captain (NATO rank code OF-2) may hold the title of "company commander", whereas an officer with the rank of lieutenant colonel (NATO rank code OF-4) typically holds the title of "battalion commander".
The title, originally "master and commander", originated in the 18th century to describe naval officers who commanded ships of war too large to be commanded by a lieutenant but too small to warrant the assignment of a post-captain and (before about 1770) a sailing master; the commanding officer served as his own master. In practice, these were usually unrated sloops-of-war of no more than 20 guns. The Royal Navy shortened "master and commander" to "commander" in 1794; however, the term "master and commander" remained (unofficially) in common parlance for several years.[1] The equivalent American rank master commandant remained in use until changed to commander in 1838.
Various functions of commanding officers were also styled commander. In the navy of the Dutch Republic, anyone who commanded a ship or a fleet without having an appropriate rank to do so could be called a Commandeur. This included ad hoc fleet commanders and acting captains (Luitenant-Commandeur). In the fleet of the Admiralty of Zeeland however, commandeur was a formal rank, the equivalent of Schout-bij-nacht (rear-admiral) in the other Dutch admiralties. The Dutch use of the title as a rank lives on in the Royal Netherlands Navy, as the equivalent of commodore. In the Royal Netherlands Air Force, however, this rank is known by the English spelling of commodore which is the Dutch equivalent of the British air commodore.
The rank of commander in the Royal Australian Navy (RAN) is identical in description to that of a commander in the British Royal Navy. RAN chaplains who are in divisions 1, 2 or 3 (of five divisions) have the equivalent rank standing of commanders. This means that to officers and NCOs below the rank of commander, lieutenant colonel, or wing commander, the chaplain is a superior.
To those officers ranked higher than commander, the chaplain is subordinate. Although this equivalency exists, RAN chaplains who are in divisions 1, 2 or 3 do not actually wear the rank of commander, and they hold no command privilege.
Commander is a naval rank in Scandinavia (Kommandør in Danish and Norwegian, Kommendör in Swedish) equivalent to the Anglo-American naval rank of captain. The Scandinavian rank of commander is immediately above "commander-captain" (Norwegian: Kommandørkaptein, Swedish: Kommendörkapten, Danish: Kommandørkaptajn), which is equivalent to the Anglo-American naval rank of commander.[2]
In Denmark, the rank of commander exists as kommandørkaptajn (commander captain or commanding captain), which is senior to orlogskaptajn (captain) and kommandør (commander), which is senior to kommandørkaptajn. Kommandørkaptajn is officially translated into Englis as "Commander, Senior Grade", while orlogskaptajn is officially translated as '"Commander."[3]
A commander in the Royal Navy is above the rank of lieutenant commander, below the rank of captain, and is equivalent in rank to a lieutenant colonel in the army. A commander may command a frigate, destroyer, submarine, aviation squadron or shore installation, or may serve on a staff.
Since the British Royal Air Force's mid-rank officers' ranks are modelled on those of the Royal Navy, the term wing commander is used as a rank, and this is the equivalent of a lieutenant colonel in the army or a commander in the navy. The rank of wing commander is above that of squadron leader and below that of group captain.In the former Royal Naval Air Service, which was merged with the Royal Flying Corps to form the Royal Air Force in 1918, the pilots held appointments as well as their normal ranks in the Royal Navy, and they wore insignia appropriate to the appointment instead of the rank. A flight commander wore a star above a lieutenant's two rank stripes, squadron commander wore two stars above two rank stripes (less than eight years' seniority) or two-and-a-half rank stripes (over eight years seniority), and wing commander wore three rank stripes. The rank stripes had the usual Royal Navy curl, and they were surmounted by an eagle.
In the United States Navy, United States Coast Guard, United States Public Health Service Commissioned Corps, and National Oceanic and Atmospheric Administration Commissioned Officer Corps, commander (abbreviated "CDR") is a senior-grade officer rank, with the pay grade of O-5. Commander ranks above lieutenant commander (O-4) and below captain. (O-6). Commander is equivalent to the rank of lieutenant colonel in the United States Army, United States Air Force, United States Marine Corps, and United States Space Force. Notably, commander is the first rank at which the holder wears an embellished cap, whereas officers of the other military services are entitled to embellishment of similar headgear at O-4 rank.
Promotion to commander in the U.S. Navy is governed by United States Department of Defense policies derived from the Defense Officer Personnel Management Act (DOPMA) of 1980 or its companion Reserve Officer Personnel Management Act (ROPMA). DOPMA/ROPMA guidelines suggest that 70% of lieutenant commanders should be promoted to commander after serving a minimum of three years at their present rank and after attaining 15 to 17 years of cumulative commissioned service, although this percentage may vary and be appreciably less for certain officer designators (i.e., primary "specialties") depending on defense budgets, force structure, and the needs of the service.
In the British Army, the term "commander" is officially applied to the non-commissioned officer in charge of a section (section commander), vehicle (vehicle commander) or gun (gun commander), to the subaltern or captain commanding a platoon (platoon commander), or to the brigadier commanding a brigade (brigade commander). Other officers commanding units are usually referred to as the officer commanding (OC), commanding officer (CO), general officer commanding (GOC), or general officer commanding-in-chief (GOC-C), depending on rank and position, although the term "commander" may be applied to them informally.
In the Spanish Army, the Spanish Air Force and the marine infantry, the term commander is the literal translation of comandante, the Spanish equivalent of a Commonwealth major. The Guardia Civil shares the army ranks, and the officer commanding a house-garrison (usually an NCO or a lieutenant, depending on the size) is addressed as the comandante de puesto (post commander).
In the United States Army, the term "commander" is officially applied to the commanding officer of army units; hence, there are company commanders, battalion commanders, brigade commanders, and so forth. At the highest levels of U.S. military command structure, "commander" also refers to what used to be called commander-in-chief, or CINC, until October 24, 2002, although the term CINC is still used in casual speech.
In the United States Air Force, the term "commander" (abbreviated "CC" in office symbols, i.e. "OG/CC" for "operations group commander") is applied officially to the commanding officer of an Air Force unit; hence, there are flight commanders, squadron commanders, group commanders, wing commanders, numbered air force commanders, and commanders of major commands. In rank, a flight commander is typically a lieutenant or captain, a squadron commander is typically a major or lieutenant colonel, a group commander is typically a colonel, a wing commander is typically a senior colonel or a brigadier general, a numbered air force commander is a major general or lieutenant general, and the commander of a major command is a general.
