Why do we lack a LIGHT Armageddon Knight?

[Toffee.]

Basically, some sketchy ideas for a potential candidate.

Celestial Knight
LIGHT / Level 4
[Warrior/Effect]
Once per turn, You can Banish 1 LIGHT monster from your hand: Send 1 LIGHT monster from your Deck to the Graveyard.
ATK 1400 / DEF 1200

Solaris Knight
LIGHT / Level 4
[Warrior/Effect]
If a LIGHT monster you control battles an Opponent's monster, You can send this card from your Hand to the Graveyard: Send 1 LIGHT monster from your Deck to the Graveyard. You can only use the effect of "Solaris Knight" once per turn.
ATK 1400 / DEF 1200

Radiant Knight
LIGHT / Level 4
[Warrior/Effect]
If this card is Tributed: You can Send 1 LIGHT monster from your Deck to your Graveyard. Once per turn, if another LIGHT monster you control is Tributed: You can Send 1 LIGHT monster from your Deck to the Graveyard. You can only use 1 effect of "Radiant Knight" per turn.
ATK 1400 / DEF 1200

Photon Knight
LIGHT / Level 4
[Warrior/Effect]
Once per turn, you can Send 1 LIGHT monster from your Hand to the Graveyard: This card's ATK becomes 2000 until the End Phase. Then, if this card destroys an Opponent's monster as a result of battle this turn, you can send 1 LIGHT monster from your Deck to the Graveyard. The effect of "Photon Knight" can only be activated once per turn.
ATK 1400 / DEF 1200

cuz Lightsworn I guess. Anywho:

 

Photon Knight, both belonging to an archetype and having an effect other than the send, wouldn't be favorable as it would break the chain.

Radiant seems like it would be a real one, but it wouldn't be all that great if released, if it was ever ran. Ever.

 

This leaves Celestial and Solaris. Out of the two, I'm leaning towards Celestial as it could make interesting Agent plays I guess (since Jupiter could SS whatever it banishes), however, Solaris seems overall more geared towards a competitive deck and could later on be amazing (has more potential than Celestial. I can't decide between the two, but out of the two (if released currently) I'd have to vote for Celestial. Foresight wise? Solaris.

The Photon one was silly, I know.
But anyway, as far as they go-
Dark: Upon Summon
EARTH: FLIP-Effect
WATER: Change battle position
FIRE: Destroyed in battle OR another FIRE you control is destroyed in battle; Only one with 2 effects
WIND: Return another WIND you control
So LIGHT has to be either Honest-esque(Veiler, Honest, and Bujin Crane), or follow some vague concept, hence, why Celestial is Banish because it also, to an extent, fuels Lightrays. And works better in that respect, since Dark Grepher and Lightray Grepher are cards, so it only seems natural that a LIGHT Armageddon would exist.

But overall, yea, Solis is probably the best.
