Just as Ishizu intended.
With the release of Raging Tempest in the TCG today, another older card had to be renamed. “Null and Void”, a card that was initially released in Soul of the Duelist (2004), will now be called “Muko” and has been updated accordingly on the official database. The physical reprint of the card is still unavailable.
This was done to exclude it from the “Void” archetype, which is supported through Infernoid Devyaty, Void Vanishment, and Void Feast.
