"World Legacy's Secret" Rating Score by jk-en

It has a 1) resurrection effect that can be activated arbitrarily at the time of activation and 2) a permanent effect that negates the activation effect of the opponent's monster that was activated in the same column as his Mekk-Knight on your field. Since it's an effect that is activated "on" the field, you can negate effects that are activated by releasing them from the field, and Sacrifice Escapes such as Ichiryu don't work.
A card that has the highest adoption rate among JK's column negate cards, with performance like Call of the Haunted with additional effects instead of limiting the resurrection target. Basically, it's ideal to drop azure on his GY during the deployment process, and then revive him during the opponent's turn while interfering. Since negate is a permanent effect, especially if it is a link theme, there is a possibility that you will be stuck with this one at worst.
However, in addition to being a Continuous Trap, he also has a lot of weaknesses due to the fact that this card doesn't work on its own. It is the neck that is driven into. In particular, if you activate the resurrection effect and chain it to Ghost Belle & Haunted Mansion, the activation itself becomes a negate and it doesn't even remain on the field, so if you don't need it, you need to consider not activating the resurrection effect in the worst case. In any case, I would like to add 《World Legacy's Memory》etc. in case the resurrection is hindered.
