Well, I don't have time to test it tonight, but I have to say three things offhand:
1) Awesome. While I think that Finkel does have a point about it being 'out-of-sync' with the rest of the game, I also have to say that I don't care.
needs something like this to bring it back into line with the rest of the elements, and I think that the idea of using passive skills to indicate flying (and maybe in the future swimming?) etc. is a sweet idea.
2) Crappy. It's just plain not good to have a card that says "You lose, just quit" to some decks. There's nothing like playing a game and getting told in a single move that you no longer have any chance to win. Right now, there's Gravity Shield, but it's a rare enough thing to have all high-HP creatures that it's recognized...and
every element has low-HP attackers -- except the one that comes with Momentum. With this, it's just the opposite. I play Life all the time, and to be forced to splash
for Spirits simply because my opponent might outright shut me down with Wings is lame beyond belief.
3) Animated Weapons, and all Dragons should fly, and having Wings should disable any non-ranged weapons you're using.
If it were me, I'd either make it disabled every 3rd turn (making it mechanically similar to a two-turn Phase Shield for non-flying creatures that automatically renews itself after a turn of downtime), or have it inflict 9 damage per turn on it's user.
