There are alot of flip cards in the magic plugin which do not work correctly (no backside image, flipping hint not provided).
E.g.: Docent of Perfection, Aberrant Researcher, Archangel Avacyn...
The first set from the Shadows over Innistrad block was during a transition period between two different ways of implementation of Transform cards. You can spawn the transformed side of the card by right clicking the card and clicking Transform at the bottom (a built in script)
Ah I see, why haven't all transform cards been unified then? It's very unintuitive that on some you can do it by flipping and others don't work that wy.
