rulings

• 2020-01-24Colorless and generic mana symbols ({C}, {0}, {1}, {2}, {X}, and so on) in mana costs of permanents you control don't count toward your devotion to any color.
• 2020-01-24If you put an Aura on an opponent's permanent, you still control the Aura, and mana symbols in its mana cost count towards your devotion.
• 2020-01-24If 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.
• 2020-01-24If your devotion to blue is zero at the time the triggered ability of Thassa's Oracle resolves, you don't look at or move any cards in your library. If you have no cards in your library, you win the game.
• 2020-01-24Hybrid mana symbols, monocolored hybrid mana symbols, and Phyrexian mana symbols do count toward your devotion to their color(s).
• 2020-01-24Mana symbols in the text boxes of permanents you control don't count toward your devotion to any color.
