Gaia, the Polar Knight →Used Deck

There is no self-SS effect, and the search effect of (1) requires release materials other than this card, which is very expensive.
In spite of that, the search destinations are quite limited, and on top of that, you have to send one card from your hand, so the fuel consumption is too bad.
Currently, if you have 2 Warriors on the field, you can get 《Isolde, Two Tales of the Noble Knights》, so the position of 《Gaia, the Mid-Knight Sun》and this card is pretty tough.
When this card came out, he was in the Zexal era, and just being level 4 had a certain value, so it may be inevitable that the effect has been suppressed so far. (Evaluation has been subtle since it came out)
There are also good points.
It is one of the few Warriors that works well with Lair of Darkness, and his DARK in release cost and his DARK overwrite/release simile in Dystopia are a match.
Also, with the effect of (2), you can increase your own ATK to 2100, so it can also be used as a cost for 《Deck Devastation Virus》, which works well with 《Lair of Darkness》.
It wouldn't be bad if it was possible to exchange cards while removing the opponent's monsters without question.
Along with 《Gaia, the Mid-Knight Sun》, the raw performance is 3 points, but considering the combo with Dystopia mentioned above, it will be 4 points, +1 point.

Even the condition of releasing a monster on the field for searching is heavy, so why do you need to discard your hand afterwards?
The cost of the latter half of the effect is not too heavy, so it can be used as a 2100 attacker, but he seems a bit plain as a excluding GY.

When the first half of the effect is activated, it is a card that loses the board add and loses one add. The second half effect is also very poor, despite only being up 500 and losing his GY ad. Even if this card is given to itself, it will only be up to 2100, so it will be easily broken through.

The first half of the effect is very costly, especially since you have to release the monsters on the field, but the second half of the effect is easy to use and has good performance, lasting until the opponent's turn + his ATK other than this card. Is there a certain amount of usefulness in being able to give it? However, as an effect that consumes 1 GY, it seems a little too plain. It is a card that is hard to find the reason to actively adopt it.

Along with the remake of Black Luster Soldier, the dark knight is also a chaos remake.
Neither effect is weak, but if you say it's strong...
In the first half, Hikari Senshi Search is strong, but the cost is heavy.

I want to see "the most beautiful light in the world"
The horse is white and the one on it is black.
This is fire power up. It is a big advantage that it is stronger in return turns than Byakuya. In addition, it can be applied to allies, so it is convenient when killing large monsters.
The search effect is too heavy to use properly, but it's better than white. There are Fotosla and Gawain.

Gaia is the source of his Black Luster Soldier, so Yoiyami-san is a hybrid of light and dark Gaia.
The dark pot condition of the effect is vaguely Kercion-like and makes me brace myself, but when I calmly read it again, it doesn't say much.
Regardless of the hand cost, Hikari Senshi Search can't be used quickly because the release is heavy. The other pump up is more convenient.
Is there a way to use this card as a 2100 attacker that can remove GY's light? If you put it as a spice in the light deck, you can also use chaos.

The search effect in the first half is difficult to use, and the effect in the second half is convenient, but the basic stats are too delicate to use.Summon Priest has the effect of "cannot be released", so I'm sorry.

I got one chance to enter Noble Knight
You can search Noble Knight by releasing it from Samopuri.
