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.

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.

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.

The token enters attacking. It doesn't trigger "when a creature attacks" triggers and is not subject to restrictions on declaring attackers.

You choose which player or planeswalker the token is attacking. It doesn't have to attack the same player or planeswalker as the creature that caused the ability to trigger.
