Nykthos, Shrine to Nyx

Mana symbols in the text boxes of permanents you control don't count toward your devotion to any color.

Numeric mana symbols ( 0 generic mana , 1 generic mana , and so on) in mana costs of permanents you control don't count toward your devotion to any color.

If an activated ability or triggered ability has an effect that depends on your devotion to a color, you count the number of mana symbols of that color among the mana costs of permanents you control as the ability resolves. The permanent with that ability will be counted if it's still on the battlefield at that time.
