I have literally not made as many edits with any other card than I have with Whim. *pant* *catches breath* (yes, typing is exhausting, especially for someone who hates that edit mark T-T)
Anyway, I think that Air has a lot of soft versions of mechanics from other elements, and I do agree that in a literal sense, cards being "teleported" from hand to deck and back seems like it could be in another element, however I tried to incorporate a nature of
Air into a possible creature, in another way.
Fickle is meant to invoke a characteristic of the
Air elemental, freedom, at a cost: it can get out of hand. Too much freedom, and you lose control.
It was this fine balance which I attempted to translate into the card. I may change the cost of Fickle to
if it is requested, but I personally think the mechanics behind Fickle represent quite well what
Air may represent.
