Commander is built around the idea of one legendary creature anchoring an entire 100-card deck, but Partner throws that assumption out. A card with the Partner keyword lets you run two legal commanders instead of one, each pulling its own weight from the command zone.
The mechanic debuted in Commander 2016 and reshaped how players think about color identity, deck construction, and command-zone synergy. Instead of being locked into whatever colors one legendary creature happens to be, two Partner commanders combine their identities into a single, often more flexible, deck.
Since then, Partner has spawned several variants, including Partner with a specifically named card, Friends Forever, and Choose a Background, each tightening or loosening the original rule in a different direction.
This guide breaks down exactly how Partner works, what it changes about deckbuilding, and where the mechanic has gone since its debut.
A creature with Partner can be your commander on its own, just like any legendary creature. The difference appears once you pair it with a second card that also has Partner, since both cards become your commanders simultaneously, sharing the remaining 99 deck slots between them.
Each Partner commander is tracked separately for commander tax and commander damage, meaning a 21-damage kill has to come from one of the two individually rather than their combined total across a game.
Your deck's color identity becomes the union of both commanders' identities. Two Partner commanders, each printed in two colors, typically combine into a four-color deck as long as their colors do not overlap.
This union rule is what makes Partner so useful for deckbuilding, since it opens up color combinations that would otherwise require a rare multicolor legendary creature to access directly.
Commander 2016 built its five preconstructed decks around four-color themes, and Partner gave players an alternate path into those same color identities using two separate two-color legends instead of one four-color commander.
The design team wanted every deck to offer a built-in option to break away from its primary four-color commander toward a more focused two-color build using one of the alternate Partner commanders included in the box.
Two commanders means two abilities working for you from turn one, but it also means paying two separate commander tax increases if either gets removed and recast from the command zone during a game.
Some Partner pairs lean into card advantage or ramp so heavily that they define entire archetypes, while others get chosen purely for color-identity access rather than any real synergy between their abilities.
Wizards of the Coast has continued printing Partner-keyword creatures well past Commander 2016, expanding the pool of legal Partner commanders across newer Commander-focused products over the years.
Not every Partner card is designed for the same power level, so pairing an aggressive low-curve legend with a slower value-oriented one is a common way players balance a two-commander deck's overall game plan.
A Partner commander that loses the keyword mid-game, through a copy effect or ability-removal, does not stop being your commander. It simply cannot be freely re-paired if it somehow returns to the command zone under different circumstances later.
Players new to the mechanic sometimes assume Partner lets any two legendary creatures pair up. It specifically requires both cards to have the Partner keyword printed on them, not just legendary status.
Partner's introduction in 2016 marked one of Commander's first major structural changes since the format's precon era began, giving players a legitimate alternative to the single-commander model that had defined the format from the start.
The mechanic's popularity directly influenced later design decisions, including Partner With in Battlebond and Choose a Background in Commander Legends: Battle for Baldur's Gate, both building on the same core idea of a flexible or semi-flexible second commander.
No, only cards that have the Partner keyword printed on them can be paired this way.
Two two-color Partner commanders typically combine into a four-color identity when their colors do not overlap.
No, each Partner commander's combat damage is tracked separately toward the 21-damage threshold.
Partner was introduced in Commander 2016, released November 11, 2016.
Partner turns command-zone deckbuilding into a puzzle of color identity and synergy, and getting that puzzle right rewards careful piece selection more than any single powerful card. Once you have settled on a pairing, protecting the two cards anchoring your whole deck matters, and a set of EVORETRO penny sleeves keeps them tournament-ready through repeated shuffling.
A binder with a secure elastic closure is worth keeping nearby too, since a Partner deck often means tracking down two separate legendary creatures across your collection. The EVORETRO 9-pocket binder with elastic makes that kind of organization simple.
