Hail mighty Higu, Queen of reason and dispeller of doubts. Pretty much made this card make sense AND showed it as being balanced.
Awesome rainbow emitting Light spirit art now pls.
Yeah, but unlike other rainbow-oriented cards, this card is (as it is now) completely useless in anything but rainbow. Unlike Supernovas, which is used in duo or trio (entropy+sparks+photons?) mutation decks as well. And together with Supernovas, even SoSe can be used in mono entropy (probably because of that one card which is always an entropy card)
That 2N for all unique light cards (and 1 for any other unique creature) would make this card much more interesting for a bigger field of decks. (As this would make it OP, either the quanta cost, or the ability itself needs some rework done (like the already mentioned exclusion of the divine spirit himself) I would vote for an increased quanta cost instead of some weakening in the skill...)
<-- This would also ask for the use of Light PSN-bows, something you don't see often right now... (only some Pegasus PSN-Bows are going around)
Something random I just noticed. Isn't this card gonna be interesting in Mutation decks?
