World Legacy's Secret →Used Deck

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.

Continuous Trap is super effective as an obstruction & revival card.
It's probably intended to be combined with 《Mekk-Knight Indigo Eclipse》, but unlike 《Skill Drain》, all monster effects activated in the same column as Mekk-Knight are negate.
For this reason, even monster effects that activate by releasing itself are negated, and opponents who have hardly played against Mekk-Knight often get caught in this.
If your opponent tries to put a monster in a different column than his Mekk-Knight, it will be chased with Mekk-Knight Indigo Eclipse, which is disgusting. It's fun to use!
Also, the combination with 《Mekk-Knight of the Morning Star》is disgusting.
Also, anything can be revived as long as it is level 5, so in mixed construction, you can revive 《Baronne de Fleur》, and when your opponent destroys this card, you can revive "a monster that activates when destroyed or goes to GY". You can also earn ads.
You can also search with 《Mekk-Knight of the Morning Star》or 《Lib the World Key Blademaster》.

Continuous Trap with libide and obstruction effect
Since monsters to be revived are only required to be level 5 or higher, it can be used as a general-purpose resurrection trap.
However, if you use it anyway, you want to use the effect of ② effectively. His Mekk-Knight Deck can be searched with Mekkai Knight of the Morning Star and Star Swordsman Reive, so it also functions as a solid obstruction card. The compatibility with Konpeki is especially great, and by reviving Konpeki and chasing after her line, you can target the monster effect up to twice. In addition, unlike Skidre, you can negate effects that send or release yourself to her GY at a cost due to the text "Effects of opponent monsters activated in the same column". Sacrifice Escape also doesn't work, so depending on the deck, it will be a worse card than negate traps such as Skidre and Infinite Impermanence.
Overall, it feels like Mekk-Knight's flagship jamming card that can maximize the performance of being searchable and having a negate effect.
This one card can be a very good card that will entertain players (especially those who use it) because it can change the game completely due to the tandem elements involved.

An excellent machine knight support card that also serves as negate + level 5 or higher limited libido, activated by monsters. The effects of (1) and (2) work well together, and it is very attractive to be able to interfere with one monster with this one card without relying on 《Mekk-Knight Indigo Eclipse》. This card itself can also be searched with 《Mekk-Knight of the Morning Star》, so it is easy to use.
Taking advantage of the World Legacy category, it is also possible to discard the effect of (2) and install it in the World Legacy Deck etc. as a resurrection card that is easy to search.

His Continuous Trap responsible for reviving Mekk-Knight and negate effects.
Perhaps there is no Mekk-Knight binding so that World Legacy monsters can also be adopted, but when it comes to Continuous Trap resurrection cards, there are libido and "Powerful Rebirth", and recently there is Normal Trap's "Back to the Front". Since it can be used without worrying about it, I think it would be difficult to use it outside of Mekk-Knight.
Low-level avrams and links without levels are not supported, but I think the latter half of the effect doesn't bother me too much.
Another effect is that he negates the same column monster effect as Mekk-Knight. Not to mention the strength of the monster effect negate, it is very compatible with itself, which is the resurrection trap of Furice, especially around Azure.
Including the fact that he doesn't have Turn 1, I think he's excellent as a Mekk-Knight support.

Machine Knight An excellent card in the Deck that can interfere with monsters with a free chain. The combo of searching for this card with 《Mekk-Knight of the Morning Star》and using the Link Material Mecha Knight as his Special Summon is rather troublesome, so I would like to make use of it.

Mekk-Knight's Continuous Trap is uselessly versatile.
The effect of 1 was unlikely to be a libide of level 5 or higher, but now that there are many mutual libides, there is no need to use this for the purpose of reviving.
The effect of 2 negates the effects of monsters in the same column as his Mekk-Knight.
It is very meshed with the effect of 1, and if it is set, you can aim it at the position according to the appearance of the opponent's monster and set up a negate.
It works well with Konpeki, but even if you don't have these cards, you can still aim to some extent if you're in the EX zone.

Will the story progress in a darker and darker direction?
A monster-effect version of Mekk-Knight's boasted tandem negate card. But with this card, the attached effect is more important.
The accompanying effect is the resurrection of cards of level 5 or higher. For general use, Livide and Back to the Front would be fine, but since all Mekk-Knights are level 5 or above, this card can be used to revive them.
What this means is that when this card is activated, he can negate the effect of the monster in front of him by reviving Mekk-Knight. Even after that, you can keep the effect of the monsters that stay in the field as a check, but if you want to make full use of it, you also want the azure movement effect.
His powerful Continuous Trap card that can be said to be Mekk-Knight's strength.

general resuscitation card
If you're a Mecha Knight, you can negate the effects of your opponent's monsters with Friche.

The usual World Legacy card that is both general-purpose and semi-exclusive.
For some reason, he has a lot of manure due to the GY effect and the ability to revive, so this card's revive is also effective. In other words, the resurrected monster will turn into a monster effect negate by applying (2) as it is, so the compatibility is perfect.
Regarding the column negate monster effect, in addition to the above-mentioned resurrected guy being blocked as it is, you can use the effect at a fixed position depending on whether you want to use the EX monster zone, the link destination, or other places. Monster effects that tend to be absent or biased in place are a little easier to negate than spells and traps... well, it's still difficult

A card containing libido limited to level 5 and above. However, resurrection is not a forced effect, so it can be activated even if GY is not fat. Ideally, revive the "Mekk-Knight" monster in front of the opponent's monster and negate the effect.
