Croma O poder e a resistência de Espreitador das Sombras são ambos iguais ao número de símbolos de mana preto nos custos de mana dos cards no seu cemitério.
Chroma abilities check only mana costs, which are found in a card’s upper right corner. They don’t count mana symbols that appear in a card’s text box.
This is a characteristic-defining ability, which means it functions in all zones. You include the symbols in the Stalker’s own mana cost if you need to determine its power and/or toughness while it’s in the graveyard.
