Each of these Equipment has two subtypes listed on its type line. The first one is a creature type, which in this case is also a subtype of kindred. The second one is Equipment, which is a subtype of artifact.

If you attach an Equipment you control to another player's creature, you retain control of the Equipment, but you don't control the creature. Only you can activate the Equipment's equip ability, and if the Equipment's ability triggers again, you choose whether to move the Equipment. Only the creature's controller can activate any activated abilities the Equipment grants to the creature, and "you" in any abilities granted to the creature refers to that player.

Each of these Equipment has a triggered ability that says "Whenever a [creature type] creature enters, you may attach [this Equipment] to it." This triggers whenever any creature of the specified creature type enters, no matter who controls it. You may attach your Equipment to another player's creature this way, even though you can't do so with the equip ability.

This cards was originally printed with the "tribal" card type. That card type has been replaced with "kindred". This change does not affect the gameplay function of this card.

While it appears only on cards that already have other card types, kindred is a card type and will be counted by effects that refer to the number of card types among cards in a zone.

Kindred is a card type that allows noncreature cards to have creature types. For example, Echoes of Eternity is an Eldrazi (although not a creature) while on the battlefield and an Eldrazi card (although not a creature card) in zones other than the battlefield.
