Daxos, Blessed by the Sun

If you control a battle and an opponent is its protector, you still control the battle, and mana symbols in its mana cost count toward your devotion.

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.

Colorless and generic mana symbols ( colorless mana , 0 generic mana , 1 generic mana , 2 generic mana , X generic mana , and so on) in mana costs of permanents you control don't count toward your devotion to any color.
