Advanced Crystal Beast Emerald Tortoise →Used Deck

A mysterious card that has been turned into a card with the performance of the 5th term for some reason
On top of that, the performance is by far the worst compared to other A jewels, so I think it would have been nice to have one of the additional effects.

Change the battle position of the free chain depending on the adder... Change the battle position! ? for what? ? At least put it on the back! !
Seriously, there's no use for it.

Well, it's true that it's somewhat better than the original Turtle, but you definitely won't find much more value in A Crystal Beast... either against your opponent's monsters or your own. Although you can change your battle position even during the opponent's turn, the basic situation to use this effect is when our poor A Crystal Beast is attacked, but if you just want to defend against the opponent's attack, Amber Mammoth is more convenient. On top of that, even if I saw it for the purpose of preventing battle damage, since it has "Advanced Dark", I can't think of a scene where I would use this effect without joking.
In the end, even if Turtle turned into A Crystal Beast, couldn't he escape from suffering a painful fate?

The change from the original story is that the Defense Position change, which had restrictions on activation conditions and targets, has been strengthened to free chains on top of being able to specify anything.
The usability and usefulness have increased significantly, but considering the disadvantages that A Crystal Beast is burdened with, it's plain.
As already mentioned, it does not mesh well with 《Advanced Dark》, which is essential for operation.
The effect itself is not bad, but considering the background of being affiliated with A Crystal Beast, it feels like something like that.

One of the Advanced Crystal Beasts that looks the most different from the original monster.
As a result of the development of the original effect, it has become an effect that changes the battle position of one monster that can be used unconditionally in Friche during each player's turn.
It's not a bad effect for a low-level monster that can be Normal Summoned, thanks to the fact that it's a complete Furitche at no cost, but Advanced Crystal Beast, including the nature of Advanced Dark, is already in time for combat support effects. It has a strong feeling of being in the enemy's defense position, and its own ATK is low to defeat the opponent's monster, so it is difficult to make use of the effect alone. I can't deny the feeling that it's a half-hearted effect.
The point is that the weight of the common self-destruction demerit effect and the quality of your own merit effect are not balanced...
Compared to his original Crystal Beast, Advanced Crystal Beast has many monsters with superior properties by lining up low-level monsters and maintaining the beat and battle line, but the opponent does not come on the low-level beat. There are some things that are very difficult.

The tortoise has a much more ferocious look than before.
The effect itself has also been greatly enhanced, and the opponent can also be targeted, and the combo, breakthrough, and obstructive power have been improved, such as turning it into a furiche.
However, his RBI is still poor, and the compatibility with Advanced Dark, which is essential for maintenance, is not good. Also, in this era, just changing the battle position has little influence on the opponent.
It is undeniable that it is unsatisfactory for being self-destructing and unstable.

Emerald Turtle used by Johan possessed by Yubel
In the anime, it was just sent to his GY by the effect of Advanced Dark, but now you can change the battle position of monsters, including the opponent's field, with free chain.
Not only can he protect his own monsters from attacks, but he can also use monsters with high ATK as his Defense Position and destroy them in battle.
One of the advantages of Advanced Crystal Beast compared to the original is its ability to maintain the front line of the lower class, but the resulting board is full of unsatisfactory effects even in the 9th term, let alone the current one.
If this card had at least been a back defense, or if the effect had been negate, it might have been at least as effective as a hindrance.
