Last night the following images surfaced from game shops as a first look at one of the mechanics coming in Innistrad. While the details are still unknown it looks like it will have to do with a card changing into an alternative form during some situation or game state.

The above image comes from an oversized card where these two images appear back to back. We do not believe this will be carried over in normal sized cards, but it is done this way to more strongly drive home the idea of their dual nature for this set. This is not the prerelease promo. It is an oversized card sent to stores meant to entice and invite people to the prerelease.

It looks like Garruk might be turning into a werewolf?

What do you think?
