I've been really impressed with it in painter, and they play 3-4 even with tutors.
I ran a two-of in a mono-white list and thought it performed well. It was an annoying card for a lot of decks to deal with, it pumped up Karn tokens, and I found that running Karn as a four-of is overkill. Maindeck hate for other combo matchups is always nice.
