After the advent of "heavy armored armored dragon", the investment rate of "simple fusion" has been improved to a certain extent, which can be used to solve the delayed field problem. By the way, as a five-star monster with optical properties, it can also provide XYZ materials for the Pleiades Cluster in Sheng Xing.
The reason why this card is restricted to the OCG card forbidden list of 20 15.0 1 is because of the existence of the Korean pioneer card "Lao Shen Nuo Deng", which gave birth to various magical combo. Only 1 old god can affect the game balance, so OCG limits this "simple integration".
However, even if this card is restricted, it cannot be prevented from becoming a universal plug-in, so that many card groups are forcibly occupied by this card and "Old God Norden". Therefore, starting from 20 15 10 1, "Old Norden" was finally banned, and this card naturally returned to the original unrestricted.
