I was in a three person duel, and one opponent lost. If I was using nighthowler, would I lose the x/x from the graveyard of the first opponent who lost? Or would he still have the same toughness and power?
I've been searching forums for an answer on a question Does "X" change over time?. WizardMN, if "the buff is constantly being reevaluated so if creature cards enter or leave graveyards after Nighthowler is on the battlefield, the buff will update as appropriate." is true, doesn't it make the Nighthowler a super overpowered card? Especially if I have a deck which sends lots of cards to the graveyard then it makes a basically unbeatable creature because it is more and more tough as the game progress. Unless an oponent is lucky enough to have two "destroy creature" cards (becuase he/she has to destroy it twice if I casted the Nighthowler as an aura), it's a win-button. Do I understand that correctly?
Big dumb creatures are easily dealt with, most decks play some sort of unconditional removal, many play mass removal of some kind. Also, the Nighthowler is an enchantment, which makes it even more vulnerable. Graveyard hate is a thing, and deathtouch, and forced sacrifice, etc. Plus, it can be countered when you cast it. Aura based removal ala Pacifism deals with it entirely. In short, no, a big creature doesn't mean you win. Nighthowler is a bit harder to deal with than say a Gigantosaurus, but it is not at all gamebreaking.
