Metacards for decks with different races
It is necessary for the user to unify the races to some extent, but depending on the opponent, it may be piled with this one.
However, since it is not a card that can be involved in development, there is a dilemma that the accident rate will increase if only such cards are inserted, so even if he can be inserted, it does not necessarily mean that it is better to adopt it.
Also, although it is a card that has been regulated in Master Duel, I think that the change in the environment is more important than just this card being strong.
It's a personal theory from here, but since the 9th term, since the suppression deck became popular in mass deployment, the adoption rate of the trap card itself, which cannot contribute to breakthrough in the second attack, has declined. This also has the advantage of being able to win without relying on traps as long as you control them first.
However, after the end of the 9th term, interference with hand triggers became commonplace, and the number of cases where it was not possible to lay down a control board in advance increased. On the other hand, face-down removal cards such as Cyclone were not able to deal with the preemptive suppression of monster effects, so even if they were adopted, they were only used from the side. That's why the threat of his Continuous Trap, which doesn't work as a trigger and has fewer face-down removals, probably increased.
