"I'll use Noble Knight HERO! Noble Arms Mask?" Deck 2015

Playing

This deck is made to make the most of 《Exchange of Night and Day》(hereafter referred to as Mingyoi).You can fight even if Mingyoi doesn't come, but when Mingyoi comes, it's even more stable.
At dawn, you can send darkness or light warriors to GY and search for cards with the same level of attributes that are paired with light if it's dark, and dark if it's light. Combine with Shadow Mist in Deck to gain advantage
If the opponent has Ayoi in the end and Shadow Mist in the hand
① At dawn, use Photon Slasher Search Mist to send out 2 airman searches, search for mist, and rank 4 warriors x 2 can also be used.
② Photon Slasher cannot be summoned or has already been used, etc. At dawn, Gawain Search Mist for Another Neos or Sparkman Search Gawain can special when Hikari Vanilla is present, so put out 2 and rank 4 In this case, only 2 warriors Not only that, you can also aim for light x2.Unlike ①, you can't search for the following Mist, but if you have another card that can be sent to GY at dawn, you can search for Shadow Mist and you can do the same thing, so it's the basic pattern of this Deck.
(3) Conditions where pattern (2) cannot be used, etc. Search for a HERO that can be searched with light warriors (overlay snipers are ideal) and mist during your own turn. 4 warriors x 2 can also be used, but if the overlay sniper is dropped, the opponent's ATK can be lowered, so a combo attack with Ragnazero is possible.
④ Search for 《D.D. Warrior Lady》in Mingyo Search for light warrior hero with mist.
There is also a balance with the hand, but these 4 patterns are the axis
《Noble Knight Gawayn》and E・HERO Shadow Mist support this Deck.
Noble Knight HERO, isn't it?
By the way, Artorius has the highest RBI among the Level 4 light warrior vanilla and the defense is also Halbert Line, so I chose it as a monster to call first from the guess GUY.In this Deck, there are 5 cards that can be searched from Shadow Mist, so other monsters are called from the guess GUY. I also wanted it, so I don't necessarily prioritize Artorius, such as having a hero blast
There are many cases where Ayoyo doesn't appear in your initial hand, but it's still possible to fight, and I think it's good to aim for Tsukuyomi, which can be played with Light x 2. Since you discard at least 1 card from your hand, it's not extremely easy to gain an advantage However, there are some opportunities to use it, such as sending Mist to GY, sending Overlay Sniper to GY, or when vanilla is going to rot in your hand.
After that, I'll keep it in check with Gandeva, or send Mist to his GY with his chain to search.
Also, this Deck has a high RBI in lower classes, so it's good that it's strong against lower class fistfights.

Strength

Rank 4 warriors x 2 and light x 2 are easy to put out. He has monsters such as Photothra and Gawain that can do Special Summons that don't sandwich chains, so it's easy to break through by connecting Infinity to Lightning.
Since you have Honest, even if you hit Lightning with only one material, you can be sure that it will be counterattacked.

Weakness

Cards like Thunder King Rai-Oh that block search effects. There are monsters with 1900 RBI and female warriors, so you might be able to break through Thunder King Rai-Oh, but you won't be able to use Asoku, so it's tough.
Also, if you are the type of opponent aiming for one kill, there is a possibility that you will be overwhelmed before you earn an advantage.

Customize

For those who don't want vanilla monsters to rot in their hand, it is also possible to exchange cards with 《Common Charity》etc.
Also, sending her to GY with Exchange of Night and Day is an effect, not a cost, so if she gets a chain cycle, she won't be able to send things like Shadow Mist to GY, so be careful.
Addendum: Due to the ban restrictions from October, Shadow Mist has been restricted, so this Deck based on Shadow Mist can no longer be used.
