Why 
?
He wants to represent how there's Light in . Personally, I'm against it. It fits Darkness by no means, and promotes the stereotype that Light is strong enough to survive, no matter how much Darkness there is.
You're probably right, however I wanted to create a duo-element card involving two opposites. The point in the opposites was to make it troublesome to play; also, I thought the element choice fit the image (sota?). And have you seen the difference between having a light in an already lit room and having one in an extremely dark room? The light is brighter in the darkness. 8)
You do realize the upped could become incredbily strong with hope especially since it's immaterial and and requires a less expensive duo in comparison to FFQ correct?
The upped should not be immaterial and I think that the cost should be at least be 4 | 3 since most spawners are generally expensive. Nepycros also makes a good point about the thematicness - it is possible for there to be complete light or complete darkness.
Maybe make it 
?
Then its still a light in the chaos, but it can combo with improved mutations.
No. That would make it even less thematically related (how does chaotic energy promote light? There can be absolute turmoil as well.) and would make it even easier to set up a mutant combo between Fallen Elf and this.
Also this seems really similar to Bloodhshadow's Lumineferous Aether (http://elementscommunity.org/forum/index.php/topic,7231.0.html) without the Ball Lightning part.
It could become powerful with hope, I intended it to be used with it, but it's not any more overpowered than a hope/rol/fractal deck. If you used a hope/rol/neverending light deck you would need to have all 6 Neverending Lights out to generate 6 Rol's per turn. With one fractal you could have a full hand of Rol's (up to 8) instantly and ready to play.
I hadn't compared it to the FFQ/Hope strategy when I came up with this. I figured that since Rays of Light are so weak (1/1) compared to fireflies they would need to be much cheaper. A fire buckler would just kill this strategy, so what would be the point of having an infinite supply of them? Everytime you make more they would in a turn.
The reason I gave the permanent immortality is because I thought the creatures would be vulnerable to CC, so why not make the permanent invulnerable? Compared to the spell fractal, which your opponent cannot stop, this permanent would be similar.
