Card suggestions (Light enhancements? Carrion Feeder? Etc.)

Weapon Master 9

3/2 creature

Effect: 3 Animate current equipped weapon. When Weapon Master leaves the field or is destroyed, destroy all animated weapons on your side of the field.

Either that one or,

King's Treasury 9 

3  : Animate current weapon equipped.

If King's Treasury leaves your side of the field, destroy all animated weapons on your side of the field.

With Fractal coming out, I thought this would be a fun idea to make weapons more interesting.

Carrion Feeder 6

Permanent: Whenever a monster is destroyed, gain one life.

Priest 3

3/5 creature

Effect: This creature is treated to have the effect bioluminescence, but does not generate  per turn.

Faith 5

Permanent: Your creatures with the effect "bioluminescence" can't be targeted by the opponent's Death and Darkness cards.

or maybe

Your creatures with "bioluminescence" gain +1 HP for each bioluminescence creature on your side of the field.

Seraphim 9

7/10 creature

Effect: Seraphim gains +1/1 for each creature with "bioluminescence" on your side of the field.

Because Luciferin and Light Nymph seem pretty useless as they are now. 

Conjure Quantum Golem 8 (colorless)

Spell: Sacrifice one Quantum Pillar/Tower to summon a Quantum Golem.

Quantum Golem 9 (colorless)

8/10 creature

Effect: generates 3 random quanta every turn.

Phantom Assassin 5

6/3

Effect: This creature gains Immortality after one turn has passed after this card has been played.

Bipolar Magician 2

3/2 creature

Effect: Has a 50% chance of dealing double damage. If this card does not deal double damage, it deals no damage at all for that turn.

Added some more ideas, once again I'll add more when I have time.

Faith: The second effect makes Photon/Hope decks really powerful. Not only you have a 7 damage-reduction shield, but also six 1/6 Photons countering the major problem of this powerful combo.
The first effect is doomed like Purify.

Seraphim: Useless? Making a shield that can endure even a Godzilla Otyugh is not useless at all.

I'm saying Luciferin and Light Nymph have very limited usage. In what cases would one actually want to use Luciferin? What's that have to do with my Seraphim idea? And I'm not sure if you're talking about Hope there, when I was talking about Luciferin and Light Nymph. But, Hope seems a bit limited to me, personally. When I've tried out unupgraded FFQ and Hope, I usually beat my opponents at the exact time I could get Hope on board. Thus, Hope didn't do much for that deck. For Fractal, Ray of Light, and Hope, it's easier to bring out Hope, but it's way too fragile keeping so many Ray of Lights on the field, as there are many cards that could control your creatures.

As for Otyughs, they rarely ever can reach "Godzilla" mode unless you're the one using the Otyugh against an FG. They can do decent damage, but I think they're mostly creature control with a benefit of damage in other cases such as PvP.

Limited use, but a powerful one. Your effects are powerful too.
Imagine Seraphim in a Hope deck. 5+ damage-reduction shield with some 11/14 creatures. And you can play one of those every turn with the massive light quanta you gain.

And for your FFQ/Hope deck win that fast probably against Elders. You don't need a shield for AI3 anyway.

I agree that it is pretty powerful, I just wanted to put the idea out there just in case it can be picked up and modified to be of some use.  But, it would make some sense if it was a rare that you could get from the oracle or something, I think. I don't know, I just personally feel that light lacks a place in Elements.
