Echoes of Eternity

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.

If a triggered ability is linked to a second ability, additional instances of that triggered ability are also linked to that second ability. If the second ability refers to "the exiled card," it refers to all cards exiled by instances of the triggered ability.

In some cases involving linked abilities, an ability requires information about "the exiled card." When this happens, the ability gets multiple answers. If these answers are being used to determine the value of a variable, the sum is used. For example, if Elite Arcanist's enters-the-battlefield ability triggers twice, two cards are exiled. The value of X in the activation cost of Elite Arcanist's other ability is the sum of the two cards' mana values. As the ability resolves, you create copies of both cards and can cast none, one, or both of the copies in any order.

Once an ability of a permanent you control has triggered, making it colorless won't cause that ability to trigger an additional time. Similarly, once an ability of a colorless permanent has triggered an additional time due to Echoes of Eternity's first ability, giving that permanent one or more colors won't remove that additional triggered ability from the stack.

Replacement effects are unaffected by Echoes of Eternity's first ability. For example, a colorless creature that enters the battlefield under your control with one +1/+1 counter on it won't receive an additional +1/+1 counter.

Abilities that apply "when [this permanent] is turned face up" will trigger an additional time only if that permanent is colorless once it has been turned face up.
