I also heard reports about Rob's Pernicious Deed (a card that I hadn't really considered playing for fear of destroying my own artifact mana in VC) being a really effective tool at curtailing Noble Fish and Workshop decks. So that is a neat piece of technology worth thinking about.
I'll respond here since I'm not on Facebook.
Deed is also useful versus non-Show and Tell Oath decks. Deed helped win my round one match vs Paul. He had a board of Oath, Vault/Key, and BSC but had to pass the turn. I wiped his board with Deed, bounced BSC with Jace, and won from there.
Game two versus Andy in top eight, I was facing down two Pridemages while at two life. I topdecked Deed.
Both times Deed saved me, and losing my own artifacts wasn't problematic. I'll probably continue to run Deed as long as it proves itself useful.
