Desprezo de Silumgar

Text:

Como custo adicional para conjurar Desprezo de Silumgar, você pode revelar um card de Dragão da sua mão.
Anule a mágica alvo, a menos que seu controlador pague . Se você tiver revelado um card de Dragão ou controlado um Dragão conforme conjurava Desprezo de Silumgar, em vez disso, anule aquela mágica.

Rulings:

• 2/25/2015 If one of these spells is copied, the controller of the copy will get the “Dragon bonus” only if a Dragon card was revealed as an additional cost. The copy wasn’t cast, so whether you controlled a Dragon won’t matter.
• 2/25/2015 You can’t reveal more than one Dragon card to multiply the bonus. There is also no additional benefit for both revealing a Dragon card as an additional cost and controlling a Dragon as you cast the spell.
• 2/25/2015 If you don’t reveal a Dragon card from your hand, you must control a Dragon as you are finished casting the spell to get the bonus. For example, if you lose control of your only Dragon while casting the spell (because, for example, you sacrificed it to activate a mana ability), you won’t get the bonus.
