I know that Air has control cards, but it lacks a theme. Zanz said that Air is about the freedom of movements, but I see no Air card that exemplifies that.
Flying Weapon
Now to expand on that...
I'm sure in the near future, we're going to see a plethora of
-based cards that are either going to a) be able to move all over the place on your side of the field (perhaps to counter Flooding), or other cards that allow
to get out of situations that 'limit' them. (Thinking of Flying Weapon and how it frees up a weapon slot, perhaps even more cards that free up cards in your deck or in your hand for use...).
Either way, I hope
gets represented in the War well, seeing that it's still not very popular according to some people. :|
