Yu-Gi-Oh.JP YCSJ Osaka 2019 Report

When even the company writer goes meme.

I Participated at the “Official Card Game”‘s largest Japanese event, “Yu-Gi-Oh! Championship Series Japan Osaka”!

The “Yu-Gi-Oh! Champsionship Series Japan Osaka” event was held on May 11th, 2019. This report covers it! Now, a V Jump Writer who participated at the event as a player will introduce us to how they fared.

“Why put “Exodia” in an “Infernoid” Deck?”, at first this Deck looks like it’s made of heavily incompatible cards. “Infernoid” Decks are a Deck that can easily be built at 60 cards. To take advantage of the fact “Infernoid” cards need banish other “Infernoid” mmonsters from the hand or GY to Special Summon themselves, means adding more monster.
And since you send cards from the top of your Deck to the GY equal to the difference between your Deck and your opponent’s, it’s quite easy to place monsters in the GY.

“That Grass Looks Greener”

If you have more cards in your Deck than your opponent does: Send cards from the top of your Deck to the Graveyard so you have the same number of cards in the Deck as your opponent.

Included in:
“Raging Tempest”
“RARITY COLLECTION 20th Anniversary Edition”

If you have monsters in the GY and hand, you’ll be able to pay the cost to bring out monsters to the field. This is the basic strategy of a 60 card “Infernoid” Deck. Check out the details of the Deck [ here ]!

How To Use “Exodia, Master of The Guard”

“Exodia, Master of The Guard” has a special win condition. But it’s a long and winding road to pull it off. First you have to Tribute 5 of your monsters to Tribute Summon it, and your opponent needs to have a DARK Fiend monster that they originally own. And that monster must be destroyed in battle with “Master of The Guard”. In order to satisfy all these conditions, I decided to put it in an “Infernoid” Deck.

“Exodia, Master of The Guard”

Cannot be Special Summoned. You can Tribute 5 monsters to Tribute Summon (but not Set) this card. If this card Summoned this way destroys a DARK Fiend monster that is owned by your opponent by battle, you win the Duel. This card’s ATK/DEF becomes the combined original ATK/DEF of the Tributed monsters.

Included In:

Activate its effect by Tributing the “Infernoid” monsters on your field. And by using “Lair of Darkness”.you can choose to Tribute your opponent’s monster. Also, with “Lair of Darkness”, all monsters on the field become DARK, which satisfies one of the conditions.

And, you can aim to Special Summon a Rank 7 Xyz Monster while deploying monsters. By Special Summoning “Number 42: Galaxy Tomahawk”, you can use its effect to bring out up to 5 Tokens, which you can Tribute for “Master of The Guard”.

The final condition is “Fiend Monster”. In order to satisfy this condition, we chose to include “Reprodocus”. You can change the Type of a monster it points to by annoucing the choice. With this you’ll be able to fulfill the Special Win Condition of “Master of The Guard”.

“Lair of Darkness”

All face-up monsters on the field become DARK. Once per turn, if you would Tribute a monster you control to activate a card effect, you can Tribute 1 DARK monster your opponent controls, even though you do not control it. Once per turn, during the End Phase: Special Summon as many “Torment Tokens” (Fiend/DARK/Level 3/ATK 1000/DEF 1000) as possible to the turn player’s field in Defense Position, up to the number of monsters Tributed this turn while this card was face-up.

Included In
“ストラクチャーデッキR - 闇黒の呪縛 -”

“Number 42: Galaxy Tomahawk”

2 Level 7 monsters
Once per turn: You can detach 2 Xyz Materials from this card; Special Summon as many “Battle Eagle Tokens” (Machine-Type/WIND/Level 6/ATK 2000/DEF 0) as possible, destroy them during the End Phase of this turn, also your opponent takes no further battle damage this turn.

Included In:
“RARITY COLLECTION 20th Anniversary Edition”


2 monsters
You can activate 1 of these effects.
● Declare 1 Monster Type; all face-up monsters this card points to become that Type until the end of this turn.
● Declare 1 Attribute; all face-up monsters this card points to become that Attribute until the end of this turn.
You can only use this effect of “Reprodocus” once per turn.

Included In:
“Cybernetic Horizon”

Yu-Gi-Oh! Championship Series Osaka Duel Start!

Round 1: Seki (Win)
Deck Used: 60 Card “Infernoid” Deck

Unexpectedly, I was matched up against basically the same kind of Deck (except they didn’t have Exodia in their Deck)
My opponent went first and Set cards and ended, before handing it off to me.
I added “Void Feast” to my hand with “Void Vanishment”, and then my opponent immediately activated their Set “Void Feast”, bringing out monsters. My turn ended without being able to bring out monsters.
Switching to the opponent’s turn, due to the attacks dealt by the monsters brought out, I was left with 1100 LP.
During my next turn, I drew and activated “Mystic Mine”. With this card’s effect, my opponent’s monsters couldn’t attack or activate their effects. By taking advantage of this, I took two turns to build up my resources, switched “Mystic Mine” out for “Lair of Darkness”, and won by turning the tide with attacks from “Borrelsword” and “Sjette”.

Key Deck Construction Points of Seki’s Deck
A 60 card Deck just like my Deck, but theirs didn’t include “That Grass Looks Greener”. This is because monsters aren’t intended to go the GY, while making sure Spells & Traps didn’t end up in the GY by accident.

Round 2: Aoki (Win)
Deck Used: “Marincess” + “Frog” + “Paleozoic” Deck

My opponent went first. He used the core ability of “Marincess” to use 1 monster to ultimately bring out a Link 3 monster. Then, they set a card and ended their turn.
During my turn, I had “Void Imagination” and “Twin Twisters”, allowing me to destroy my opponent’s Set card and activate “Void Imagination”. I then Fusion Summoned “Infernoid Tierra” using monsters from my Deck as material. And with its effect, we sent 3 cards from our Extra Decks and Main Decks to the GY, and by sending “Elder Entity N’tss” to the GY, I was able to destroy my opponent’s monster. I then dealt 3400 damage by attacking.
My opponent next Link Summoned “Mekk-Knight Crusadia Avramax”, which destroyed “Tierra” by battle.
From there, I Special Summoned “Onuncu” to break through “Avramax”, aiming to destroy it with an effect. “Avramax” tried to return “Onuncu” to the Deck with its effect, but since there were still other “Infernoid” in the GY, I was able win using that monster.

Key Deck Construction Points of Aoki’s Deck
It seemed to use a typical “Frog” Deck engine, while incorporating the “Marincess”. Furthermore, this Deck apparently has “Paleozoic Dinomischus” to deal with “Mystic Mine” which was used in many Decks at this tournament. It can even Special Summon itself as a monster, meaning it has great chemistry as it can become a material for “Toadally Awesome”.

Round 3: Shimizu (Win)
Deck Used: Effect Damage Deck That Uses “Mystic Mine”

My opponent started first. They Set 3 cards and ended their turn. As I started my turn, they activated “Mteverse”, which I negated with the effect of “Ash Blossom & Joyous Spring”. I then added “Void Feast” to my hand using “Void Vanishment”, and to set up for further plays I Normal Summoned “Infernoid Decatron”, and using its effect, I sent “Infernoid Onuncu”.

During the next turn, when my opponent announced they’d activate “Mystic Mine”, I activated the effect of “Decatron” by Tributing it, negating the activation of “Mystic Mine”. And from there, I activated “Void Feast”, bringing out “Infernoid” monsters. During my turn, I determined my opponent was using an effect damage Deck, so I aggressively attacked with my monsters, resulting in my win.

Key Deck Construction Points of Shimizu’s Deck
They applied to the “Yu-Gi-Oh! Champsionship Series Japan” with their friends, saying “This is a card game event”, as they had just started the “Official Card Game”. Therefore, They hadn’t really played the “Official Card Game” until now, so I built a Deck that could easily be built even if you haven’t played the “Official Card Game” before. The point is “Mystic Mine” can be used to your advantage because you don’t run too many if any monsters.

Round 4: Mitsuta (Win)
Deck Used: “Red-Eyes” Deck

I went first. I wasn’t able to make any real moves and ended by turn by setting “Obliterate!!!”.

During my opponent’s turn, wehn they announced they would be activating “Cynet Mining”, I used “Ash Blossom & Joyous Spring” to negate it. Afterwards, they Summmoned a “Tenyi” monster to Link Summon “Warrior Monk of Tenyi”.

It dealt damage to my LP.

During my turn, I drew “Void Imagination”, and I used monsters from my Deck to Fusion Summon “Infernoid Tierra”, and with its effect, I used roughly the same cards from the 2nd round to destroy the opponent’s cards. Then I used the effect of my “Obliterate” to use the “Exodia, Master of The Guard” sent to the GY to return the opponent’s monster to the Extra Deck. During my opponent’s next turn, my opponent ultimately failed to regain their footing, resulting in my victory.

Key Deck Construction Points of Mitsuta’s Deck
In this match, I thought I was Dueling a “Tenyi” Deck, because I only saw “Tenyi” monsters and “Cynet Mining”, but the Deck I found out was actually a “Red-Eyes” Deck. Originally, it was apparently a “Red-Eyes” Deck supplemented by “Guardragon” cards, but Mitsuta apparently added the other cards like “Tenyi” as an accent. By bringing out Xyz Monsters like “Red-Eyes Flare Metal Dragon”, they could aim to Rank-Up using cards like “The Phantom Knights’ Rank-Up-Magic Launch”.

Round 5: Nishijima (Lose)
Deck Used: “Magical Musket” Deck

My opponent went first to start. They steadily brought out monsters, allowing them to gather “Magical Musket” Spell & Trap Cards in the hand. Things moved to my turn, as I could only bring out “Infernoid Decatron” and do basically nothing else. I drew “Lair of Darkness” and played it to try and set up my combo that I introduced during the Deck Commentary, but next turn, it was destroyed by my opponent playing “Harpie’s Feather Duster”. With no monsters, Spells or Traps to really oppose my opponent, I ended up losing.

Key Deck Construction Points of Nishijima’s Deck
It seems to be a Deck with thought and care put into it since “Magical Musket” first appeared. By going first, they were able to set things up, resulting in me costing my own loss. Also, “Harpie’s Feather Duster” was included in masse at this tournament, likely with “Mystic Mine” on players’ minds.

Round 6: Fujimoto (Lose)
Deck Used: “Zefra” Deck

The Duel started with my opponent going first, again. Since their opening hand was less than ideal, they activated “Zefraath” in their Pendulum Zone, using its Pendulum effect to place monsters into the Extra Deck to set up further players.

Mocing to my urn, I used “One for One” to Special Summon “Infernoid Decatron” and used its ability to send a monster from the Deck to the GY. With “Vanity’s Fiend” in my hand, I Tributed “Decatron” to Tribute Summon it. I intended to seal off my opponent’s Special Summons, but before I could seal the deal, my opponent destroyed “Vanity’s Fiend” with “Zefra War”. During that turn, they defeated me using “Borrelsword Dragon” and other monsters.

Key Deck Construction Points of Fujimoto’s Deck
It seems they chose “Zefra” because of its ability to fight equally well going first or second in a Best of 1 format. It seems they included “Zefra War” to deal with troublesome cards like “Mystic Mine” and “Vanity’s Fiend”.

Ultimately I was eliminated from the tournament with 4 wins and 2 losses. If I had won one more time, I’d of made it to the final round of the qualifiers, which disappointed me that didn;t. Also, I never managed to get off “Exodia, Master of The Guard”‘s special win condition, as it tended to be sent to the GY with the effect of “Obliterate!!!”.

Duelists I Met At The Event!

After losing in the qualifiers, I interviewed players. I will introduce the Duelists I interviewed! Also, I fought in the Duelist Festival, using a “Shaddoll” Deck.

2018 World Championship Series Japanese Representative: Hasegawa

They participated with a “Gandora” Combo Deck. At the YCSJ held last year, based on the fact many players chose to go second, he chose a Deck designed to win by going First. It was built to fight with both its combo, and the ability to strike if it had to go second.

2018 World Championship Series Japanese Representative: Hinkinson

They participated with a “Salamangreat” Deck. They chose it as a Deck that could be used flexibly depending on the situation. One of the tech cards they added based on what they expected at this tournament was “Paleozoic Dinomischus”. Banishing the opponent’s cards is extremely powerful, as it’s extremely difficult for the opponent to deal with.

At the Duelist Festival: Lawrence

They used an “Orcust” Deck. They also played at the qualifiers for the YCSJ, and moved to the festival after being eliminated. In the “Orucst” Deck they used, they included “Orbital Hydralander”. It destroys cards without targeting, and can send cards from the Deck to the GY. It seems they recently fought an “OCG Instructor”, so it’s possible he might play as an Instructor at events in the future!

At the Duelist Festival: Ueda

They used a “Cyberse” Deck while playing me, but they also had the following:

“Infinitrack” + “Train” Deck
“Rokket” Deck
“Lunalight” Deck
“T.G.” Deck

They said they got interested in the “Official Card Game” due to “Duel Links”, and decided to participate in an event for the first time. They said they got to enjoy playing against all sorts of Decks.

At the Duelist Festival: Sena

They applied to the YCSJ with their family from Kanto, and said they enjoyed the Festival after losing in the Qualifiers. When I fought them, they used a “Witchcrafter” Deck, but they also had a “Sky Striker” + “Trickstar” Deck on hand. They said they don’t usually participate in card game events, but they enjoyed it this time around.

There was a tense air among Duelists during the main event, but overall people seemed to be enjoying themselves. Quite a number of the players at the Festival were first time participants, resulting in a very peaceful atmosphere where both children and adults could play. Everyone brought their favorite Decks, and it was a chance to Duel with all sorts of Decks on hand!

The Limited Edition Products Are Was Pretty Lively!

At the “YCSJ”, there were limited edition goods on sale and collaborative foods available! It’s likely future events will sell similar products.

Throughout The Event

Following the previous Tokyo tournament, I participated as a player. I had fun playing against all my opponents, and they were easy to have interviews with. Because this event is scheduled to be held elsewhere in the future, please make sure to invite friends and colleagues to join you if you’re interested.

The next “Yu-Gi-Oh! Championship Series Japan” will be held in Tokyo!

We look forward to providing information on various events at the future!
