"Stellarknight Constellar Diamond" Rating Score by シエスタ

One that wasn't used properly. The positive impression is just right now.
The material specification is quite strict, and if you want to get the star factor bare, you'll probably use Capella, but it's not worth it. It's not that Constellar can't be put out, but there is a existence that should be prioritized.
It will be put out mainly by stacking it on Stellarknight X. Something like Triveil after the effect is activated would be suitable. However, since it is a development in main 2, if you want to attack, you will have to rely on Vatraimus. It's also not worth it.
As for the effect, it seems to be conscious of his secret setting with Shaddoll, and it has a strong meta effect against Shaddoll, such as suppressing GY fertilization and collection actions.
Not only Shaddoll but also many of his decks do this, so there are quite a few effective opponents.
The effect of 2 is the same, and since darkness itself is a major attribute, there are many opportunities to use it.
There is a bit of a peculiarity in how to put it out, and the effect is a little dependent on the other party, so the quirk is a strong impression. Well, as mentioned above, the effective opponent itself is wide, so I think there is no loss even if you prepare it.
