This Ravenloft artifact has some interesting possibilities. First off, any champion with it attached, becomes gains the attributes flying and undead (vampire), though the vampire addition currently means nothing in the game. These same effects can be gained with magic items (Flying Carpet (49/AR) is perfect if all you need is the flying ability).
The better ability takes effect when attached to Strahd Von Zarovich (100/RL), which makes all champions in the pool (and battle) flying undead (vampires). This can work very well when combined with cards like Haven of the Undead (71/4th), Throne of Bone (462/4th), or Favorable Winds (24/DR).
However, cards set against any of these types (like Wind Dancers (275/1st), Water Hunters (276/1st), and Gloriana (3/1st-chase)) will now be able to crush you. Therefore, one must look very closely before deciding to use this card.
This will show up in some attack decks to grant the flying ability, but this would be better using Nature's Throne (461/4th). Therefore, the best defense against this is a good anti-flying card, like the Rod of 7 Parts, #6 (26/AR).
