Tempo is written all over this new adventure card, whether you consider its instant or creature side. In the first case, you can easily remove a big blocker. And in the case of a flying Faerie, you can play it using the Flash mechanic, which will let you unleash surprise attacks at the end of the turn.
This card will be huge in any Blue-Black Faerie deck precisely for the reasons. The flexibility has always been an enormous boon for tempo decks, and this one will undoubtedly prove its worth.
