Q:Quick question: My boyfriend and I are debating about whether or not the effect of Grave Pact stacks when you have multiple in play on one side of the field. I'm convinced that it should, being separate instances of the effect, and because nothing on the card indicates otherwise or restricts your ability to play more than one. He thinks not, and he's the more experienced player. Care to settle the matter?
You are right! Each instance will trigger whenever one of your creatures would die (and is mandatory to boot).
