So jelous that you actually have my deck fully foiled :D Long-Stemmed Pipe and Momentous Gathering make the real backbone of my deck (many of my decks), that's what allowes it to be so stable and flexible. I actually have a newer version in the making that's very heavily built around abusing Shadowplay and the discarded when played rule. Might be weaker vs the broader field of expanded decks, but definitely better in a cutthroat competitive meta that way.
