What it does
"Friends" isn't an official Magic keyword or rules term—you won't find it in the comprehensive rules. If you saw it on a card, it's almost certainly flavor text, a casual nickname, or part of an Un-set/joke card mechanic rather than an evergreen ability like flying or trample.
In casual Commander conversation, "friends" sometimes refers loosely to your team in multiplayer politics, or to creatures you control collectively. It carries no mechanical weight on its own—a card must spell out exactly what it does (e.g., "creatures you control" or "permanents you control").
If you're looking at a specific card and trying to figure out what it does, check its actual rules text and any reminder text in parentheses. If "Friends" appears, share the full card so the real interaction—likely tied to a defined term—can be explained accurately.
