Each creature with the greatest mana value has protection from each color.
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.
If there's a tie for highest mana value, all of those creatures have protection from all colors.
This effect is checked continuously. If a new creature enters with the highest mana value, it gains protection from all colors and the previous highest loses it.
If a creature has X in its mana cost, that X is treated as 0 for the purposes of this effect. It doesn't matter what the value of X was while the creature was on the stack.
