Artefact
Votre dévotion à chaque couleur et à chaque combinaison de couleurs est augmentée de un.

: Ajoutez un mana de la couleur de votre choix. Si vous contrôlez un dieu, un demi-dieu ou un enchantement légendaire, vous gagnez 1 point de vie.
The last ability of Altar of the Pantheon is a mana ability. It doesn't use the stack and can't be responded to. You'll immediately add mana and gain 1 life, if applicable.
Your devotion to two colors (for example, your devotion to red and green) is increased by one, not by two or three.
If Altar of the Pantheon loses its abilities, you'll still get a bonus to your devotion. This is because its effect is applied before any effect that would make it lose its abilities.
You gain just 1 life, no matter how many Gods, Demigods, and/or legendary enchantments you control beyond the first.
