"Welcome Labrynth" Rating Score by みめっと

With no cost, activation conditions, or phase designation, it is the supreme Normal Trap that allows you to easily recruit the highest grade Labrynth from the Deck with a complete flitch. There is also a "Welcome Labrynth" card that can be added.
There is no particular disadvantage for the monsters that appear, but after activation, he will be limited to the races he can Special Summon from the Deck/EX Deck, so the range of uses as a material for Special Summon is quite wide. It becomes narrow.
On the other hand, in the case of a construction that mainly throws away the EX Deck from the beginning with strong gold and panish, it is not a big disadvantage, and furthermore, since the Special Summon from the hand and GY is not restricted, Nibiru and Tengoku etc. I won't disturb you.
While having this effect, it can be reused many times with later effects. If you don't bring it into the game, it's difficult to recycle it over and over again, and you'll need a separate Normal Trap to keep the monster out of play each time, so I think it's okay to think of it as a powerful convenience effect if you get hooked on it.
After all, just being stopped by a warning or something like that once doesn't mean it's all over, so that alone is a great card.
