That being said, I still think leyline of Sanctity might have a place in this deck. Targeted Discard is a big game against us, and pact of Negation doesn't do anything against it, while Leyline just shuts it down.
Out of curiosity grad Student guy, how hard has it been for you to cast abrupt decay? I ask because in goldfishing with the deck, getting two spare mana that aren't being used for going off can be a bit of a challenge.
