Magic has printed four different keywords that let a Commander deck run two commanders instead of one, and it is easy to assume they all work the same way. They do not, and the differences matter for what you can legally pair together.
Partner, the original version from Commander 2016, lets any card with the keyword pair with any other Partner card. Partner with a named card, introduced in Battlebond, locks that flexibility down to one specific counterpart.
Friends Forever and Choose a Background each add their own twist, one built for a single crossover product and one built around an entirely new enchantment subtype.
This guide lines up all four so you know exactly which cards can legally share your command zone.
A card with plain Partner can pair with any other card that also has plain Partner, regardless of what set either was printed in. This is the version introduced in Commander 2016 across fifteen bicolored legendary creatures.
Because any two Partner cards can combine, Wizards of the Coast has to design each one conservatively, since a card needs to be balanced against pairing with every other Partner commander that exists, not just one intended counterpart.
Partner with [name] restricts the pairing to one specific card, printed as reciprocal pairs in Battlebond. When one half enters the battlefield, its controller may search their library for the named partner and put it into hand.
Because the pairing is locked, Wizards can push each half's power level further than a free-choice Partner card, since the design only has to be balanced around its one known counterpart rather than the entire Partner pool.
Friends Forever appeared exclusively on the Secret Lair Drop Series: Stranger Things cards, functioning as a renamed Partner restricted to seven legendary creatures from that single crossover release.
Friends Forever cards cannot combine with plain Partner cards, even though the two mechanics work identically otherwise. The separate name keeps Stranger Things legends from being folded into the much larger general Partner pool.
Choose a Background, introduced in Commander Legends: Battle for Baldur's Gate, pairs a monocolored legendary creature with a legendary Background enchantment rather than with a second creature.
The Background adds an ability or stat boost to your commander and contributes to the deck's color identity the same way a second Partner commander would, even though it is not itself a creature.
Partner offers the most flexibility since any two cards with the keyword qualify, while Partner With and Friends Forever narrow that down to one fixed counterpart each, trading choice for a tighter, often stronger design.
Choose a Background is the outlier structurally, since one half of the pairing is an enchantment rather than a creature, giving your commander an extra static ability instead of a second full legendary creature's worth of stats and text.
Mixing and matching across these keywords is not legal. A Partner card cannot pair with a Friends Forever card, and a Choose a Background creature cannot use a second creature in place of its Background.
Knowing which keyword a card actually has, rather than assuming legendary status is enough, prevents an illegal deck list from showing up at a tournament or a casual pod's deck check.
Because these four keywords look similar at a glance, checking a card's actual Oracle text on a resource like Scryfall before assuming its pairing options is the safest way to avoid a legality mistake.
Deckbuilding software and official Commander deck-building tools typically flag illegal pairings automatically, which is a useful backstop for paper players who want to double check before a game.
No, the two keywords are incompatible even though they function almost identically.
Partner with a named card was introduced in Battlebond in 2018.
Choose a Background debuted in Commander Legends: Battle for Baldur's Gate.
No, it only appeared on the Stranger Things Secret Lair Drop cards.
Knowing exactly which keyword a card carries keeps your deck legal and helps you find the pairing that actually fits your strategy instead of just chasing any two legendary creatures. Whichever route you build toward, a pack of EVORETRO matte sleeves keeps your command-zone cards glare-free and easy to read across a long table session.
A dedicated deck box built for Commander-sized decks also helps keep your two commanders from getting separated from the other 99 cards between games. The EVORETRO plastic deck box holds a full 100-card Commander deck comfortably.
