Why falcons? I have no idea...I just like falcons...
It's a lot of damage, I'm sure, but one plague or rain of fire or eagle's eye will pretty much destroy a strategy and bringing 6 quints along is just...no.
Air needs a decent rush.
I like the no-fractal. However, you are still vulnerable to opponent's fractal.
I don't like the fluff. Falcons are very solitary hunters, so this doesn't match the card's mechanic at all...
Why not give it:
a) a fantasy name
b) call it swarmbird or something
c) give it the name of a bird that hunts in flocks
