I can get 100+ light quanta easy with any FFQ (un upped) deck or FG killing RoL/Fractal deck. This is OP? Especially since it attacks every turn, and four times a turn with adrenaline.
What do you mean, +100 light quanta? It's VERY hard to get that with FFQ producing fireflies every turn.
You'd have to be using creatures that utilize Air and Shadow (Firefly Queen and Shadow Dancer), then throw up Life quanta into the mix also (for Adrenaline and the FFQ's ability, which is just too much at once). I don't think this should necessarily be included in a trio-deck, since it's pretty hard to do so. My main objective with this card is to have it create synergy between light and darkness (which to me, is very lacking in the game). Initially I had it only use
quanta, but that made mono-darkness even more powerful, which isn't what I want.
I see your point with RoL/Fractal, but again, you're going to need to generate that
quanta somehow to play these guys down, and unless your opponent has no way of getting rid of RoL easily, then yes, this card can be especially OP.
I suppose I'll have to do another edit, but I still have a general concept of this card: play it, and now you have a physical shadow that can be used to damage your opponent, but
if you want to get the most use out of it, you need some form of light.
