They indicate which player the cards belong to and allow to follow which cards have been activated.
You flip the Color Token on the deactivated side once a card has been activated. They are also used for certain card mechanics and during game occurences.
Each card has a value, located on the top right corner of the card. It serves 2 purposes:
1/ Deck building: each deck must be 125 points or less, and must be comprised of 23 cards.
2/ End of the game: the card values are added to give the final score (see "End of Game"" below).
All cards placed or moved on the battlefield must be adjacent to another. Meaning sharing a border with an ally or enemy card. To attack an enemy card, it must be adjacent to yours.
GOAL OF THE GAME
To have more points on the Battlefield than your opponent at the end of the 9th Round, to do so you must destroy their Creatures and conquer their Lands.
5 STEPS OF A ROUND
With the exception of the first Round, each player will draw 2 cards during this phase.
Card Placement Phase
The player beginning the Round must place 2 cards from their hand face down, one after the other. Then their opponent does the same.
The players simultaneously reveal their cards and place their color tokens on the intended area, on the gem.
The player beginning the Round can activate all or some of their cards placed on the Battlefield (and Astral Plane), in the order of their choosing (when a card with a token is activated, the token is flipped to the deactivated side). Once their turn is finished, their opponent can then activate their cards.
End of Round Phase
The players flip their color tokens on the active side and discard the necessary cards
END OF THE GAME
After the End of the 9th Round, each player adds the values on the cards present on the Battlefield with a token of their color. The player with the highest added values wins the game.
