How to Use

Protector with Eyes of Blue & The White Stone of Ancients

When it’s Normal Summoned, Protector with Eyes of Blue allows you to Special Summon a Level 1 LIGHT Tuner from your hand. You can Normal Summon Protector with Eyes of Blue and use its effect to Special Summon The White Stone of Ancients or since it’s not stated otherwise, even another copy of Protector with Eyes of Blue.

Once per turn, by sending 1 Effect Monster you control to the Graveyard, Protector with Eyes of Blue allows you to Special Summon a “Blue-Eyes” monster from your hand. If you send The White Stone of Ancients to the Graveyard with this effect, during your End Phase, you will be able to Special Summon a “Blue-Eyes” monster directly from your Deck. You can also send Protector with Eyes of Blue itself to the Graveyard to activate its effect and Special Summon a “Blue-Eyes” monster from your hand.

Cosmo Brain

You can Special Summon Cosmo Brain from your hand by sending 1 non-Effect Monster from your hand or face-up field to the Graveyard; Cosmo Brain gains ATK equal to the Level of that monster. Since both Blue-Eyes White Dragon and Dragon Spirit of White, which is treated as a Normal Monster while in your hand or Graveyard, are Level 8, Cosmo Brain will have 3100 ATK, which means that, with Beatdown, it will be able to get Ancient Gear Reactor Dragon under Ancient Gear Castle.

Once per turn, by Tributing an Effect Monster, Cosmo Brain allows you to Special Summon a Normal Monster from your hand or Deck. You can Tribute The White Stone of Ancients, Protector with Eyes of Blue, Dragon Spirit of White or even Cosmo Brain itself to Special Summon a Blue-Eyes White Dragon directly from your Deck.

Dragon Spirit of White

When it’s Normal or Special Summoned, Dragon Spirit of White allows you to target a Spell/Trap Card your opponent controls and banish it. You can send Dragon Spirit of White to the Graveyard to Special Summon Cosmo Brain and then Special Summon it via Silver’s Cry.

If your opponent activates Shien’s Dojo or Geartown, do not chain Silver’s Cry to it. Set your Toggle Button to ON, let their card resolve and then activate Silver’s Cry. If Silver’s Cry is activated as Chain Link 2 or higher, Dragon Spirit of White’s effect will miss the timing.

If your opponent controls a monster, you can Tribute Dragon Spirit of White to Special Summon a Blue-Eyes White Dragon from your hand. You can banish The White Stone of Ancients from your Graveyard to add a Blue-Eyes White Dragon from your Graveyard to your hand to Special Summon via this effect.

The Extra Decks

Stardust Dragon can be Summoned by using Cosmo Brain and The White Stone of Ancients or Protector with Eyes of Blue as Synchro Material. Stardust Dragon is primarily used in the Yubel matchup.

If this card is Special Summoned, Dragon-Type monsters you currently control cannot be targeted or destroyed by card effects until the end of the next turn. Azure-Eyes essentially provides protection against a plethora of cards that are fairly common in the current meta such as Paleozoic Canadia, Treacherous Trap Hole and Karakuri Ninja mdl 339 "Sazank".

Once per turn, during your Standby Phase, Azure-Eyes can Special Summon a Normal Monster from your Graveyard, meaning the Dragon Spirit of White or the Blue-Eyes White Dragon that you have likely used to Special Summon this card.

If your opponent Special Summons a Lava Golem to your side of the field, you can get rid of it by using it as Synchro Material to Summon Giganticastle.

Beatdown will allow your Dragon Spirit of White to get over Legendary Six Samurai - Shi En. Since it’s quite easy to get multiple Level 5 or higher monsters on the field at once, even big threats such as Ancient Gear Reactor Dragon will not be an issue.

Since this deck can generate a few weak or unplayable hands, you can opt to sacrifice offense in favor of consistency.

Matchups

Six Samurai Matchup (Favorable)

Dragon Spirit of White can be used to banish Shien's Dojo, preventing the opponent from Special Summon Secret Six Samurai - Fuma from the Deck and thus from Synchro Summoning Legendary Six Samurai - Shi En.

Now that Six Samurai decks do not have access to Treacherous Trap Hole anymore, you can swarm the field more safely since the only way your opponent could have to punish that would be Six Style - Dual Wield, which is a Trap Card that is usually really easy to identify and neutralize via Dragon Spirit of White. Overall Six Samurai decks do not deal particularly well with any deck that is capable of Summoning high ATK monsters so consistently.

Geartown Turbo Matchup (Favorable)

Dragon Spirit of White can banish Geartown and Ancient Gear Fortress and, without an Ancient Gear Reactor Dragon on the field, Geartown Turbo decks are really not that difficult to deal with. Even if your opponent does manage to Summon their main monster, both Blue-Eyes White Dragon and Cosmo Brain are able to get over or, at the very least, tie with it in terms of ATK thanks to Beatdown.

Koa'ki Meiru Matchup (Neutral)

Koa'ki Meiru Ice is able to wipe your entire board by itself and, if your opponent banished Diamond Core of Koa'ki Meiru, Treacherous Trap Hole will be completely useless against it.

Fortunately for you Koa'ki Meiru Ice’s effect does have an activation cost. You can Tribute Dragon Spirit of White to Special Summon Blue-Eyes White Dragon in response to Koa'ki Meiru Ice’s effect, forcing your opponent to expend more resources, or just use Silver’s Cry to Special Summon one of your monsters during the Battle Phase.

Neos Control Matchup (Slightly Unfavorable)

Karakuri Ninja mdl 339 "Sazank" and Lava Golem can be quite problematic to deal with. You shouldn’t Summon more than one monster if you don’t want them to get Tributed, but leaving a single one on the field also makes you vulnerable.

Neos decks focus on whittling down the opponent’s resources, taking control of the field by sending your monsters to the Graveyard or back to the hand and then finishing you off with high ATK Fusion Monsters that can be easily Summoned via Koa'ki Meiru Ice
Neos Fusion or Miracle Contact.

Why is it still on the tier list, it loses to almost everything except Ancient gears..

Yet it can lose to Ancient gears too, if you go first with only Dawn knight in your hand

I don’t think this deck is tier 3 anymore
Too many bad mutch ups: desperado, vendreards, darklords, fortune lady

You need to save gems.
When you reach 9999 - 15000 gems, buy Tier 1 deck from the newest or upcoming box.
Do not try to collect cards for the deck that are in the top right now, they will lose relevance before you finish.
This is a free to play way.
Good luck!

If you cannot win without that skill, then your deck sucks

It is good that you do not know how to play with this deck because it has less risk of being limited as samurai and neos fusion for example hehe

Less risk being limited but more risk being bricked.

Solid Dragon is the sleeper monster in this deck. Great card. Especially since White Stone

Solid Dragon is a great sleeper card? Lol no, it was not good at all on arrival, and only becomes decently usable after we got the newer White Stone.

> thats why we use 1 solid dragon along with 3 white stone of legend

LOL if something, normal people use it with 3 Protectors with eyes of blue and this is a completely different build than Snipe hunter build

I tried the standard one and I always draw Solid dragon earlier than the egg and thus without a single way to special summon it

How about running baggy sleeves with this deck?

Actually, I am still using Vampires. In an ironic twist, they work well against most of actual meta. Vampire Kingdom checks Neos/RE Fusion and Vamp can steal big mons such as Desperado, AG or BEWD. Not KoG material, I'll admit, but still carries me to Legend.

Do you know the difference between a good deck and a bad one?

Bad deck - you try to dance around your opponent’s 🔥

Good - you just sit on this 🔥 while the enemy jumps around you
