 * Q: Is the Gate of Moonless Night Zetsu ability different from Gate of Moonless Night?
 * A: Yes, the timing for both abilities are different, instead of triggering when a magic tool is put into the battle zone, the Gate of Moonless Night Zetsu triggers at the end of each turn if there are a total of 6 or more magic tools in the graveyard or battle zone. Furthermore, because there is no specific requirement on the number of magic tools that must be present in battle zone or graveyard, it is possible to choose all 6 magic tool from graveyard.
