"Prohibition" Rating Score by カディーン

A piece full of hate that completely seals a single card.
In the first place, since it was a card from a time when the rules were sloppy, it wasn't clear what to seal for a long time.
Even in the current text, "cannot be summoned", "cannot activate cards", and "cannot attack or change battle position" are remnants of the miscellaneous rule era that does not work because it is prohibited to put it on the field itself.
Now that the ruling has been finalized, the thorough prohibition that does not allow any loopholes has been evaluated, and it has become a side agent for experts.
Like Albus, he can be fatally wounded.
It contains a lot of text and rulings that are unique to this card (and Psi-Blocker, which uses its effect), and it doesn't even allow you to set "You can't put it on the field." unusual effect.
"Can't be used as materials for Special Summons that require materials" is a wonderful restriction that prohibits even the use of materials by future summoning methods.
What you want to be careful about is that it can be referenced. Even if he declares "Blue-Eyes White Dragon", he will be able to get "Blue-Eyes Jet Dragon" if he has Blue-Eyed Hakuryu in GY, and even if he specifies "Numeron Calling", it will still be "Numeron Network". You can do it from here.
In the old days, it was okay to set or create a fusion material, but Konami was very good at setting up the rules without neglecting it.
However, the troublesomeness is rather accelerated, and serious memory problems occur due to the fact that the effect affects the undisclosed information called the set and the behavior of not prohibiting the card before activation. Be aware that when a set card falls into his GY, it is obligatory to check it one by one and record which cards are unaffected.
Even so, there are cases where you have no choice but to ask the judge for help, such as when a set card returns to your hand, so talk to the judge in advance.
In that sense, it's for geniuses.
