Literally a deck from a Star Trek episode.
Not confirmed for release, et. al. but whether you believe it or not is your problem!
ギャラクティカ・デジャヴュ Galactica Deja Vu
Level 2 LIGHT Galaxy Effect Monster
【REQUIREMENT】 If your opponent has 4000 or more LP, you can activate this by sending this face-up card you control to the GY.
【Effect】 Send the top card of your Deck to the GY. If that card is a Level 4 or lower LIGHT Galaxy Normal Monster, you can Special Summon that monster to your field face-up. Then, inflict damage to your opponent equal to the original ATK of the monster Special Summoned by this effect.
All of Nishaw’s puns are increasingly painful jokes on being unable to decide on something, which fits his race’s Star Trek-esque alien nature of being incredibly indecisive.
幻獣キメラーレナイ Genjuu Chimerarenai (Phantom Beast Undecided Chimera)
Level 4 DARK Beast Normal Monster
Note: This card’s name is a play on Chimera, the mythical beast, and きめれない (kimerenai), which means to be undecided on a matter.
英雄獣フダン Eiyuujuu Fudan (Hero Beast Fudan the Vacillator)
Level 3 LIGHT Beast Normal Monster
Note: Eiyuudan means “Heroic story”, Fudan can mean “Indecisive”. Also Fu can mean Axe, so there’s a non-zero chance this monster is referencing “The Honest Woodcutter”, a classic Aesop story about honesty and decision.
超冥帝竜ジュゲムジュゲム Choumetiteiryuu Jugemu Jugemu (Jugemu Jugemu the Auspicious Supreme Underworld Monarch Dragon)
Level 7 DARK Wyrm Effect Monster
【REQUIREMENT】 You can activate this by sending the top card of the Deck to the GY.
【EFFECT】 Choose 1 face-up monster your opponent controls and it loses 500 ATK or DEF until the end of the turn. Then, this card gains 500 ATK until the end of the turn. But during this turn, this card cannot attack the chosen monster.
Note: This card is a reference to Jugemu, a popular story in Rakugo, a kind of Japanese comedic entertainment. It’s often used as training for Rakugo entertainers.
The long and short of it for anyone who doesn’t click a link is a father wants to have his kid have an auspicious fancy name to bless him with an auspicious long happy life. He asks a monk for a name. The monk gives him a list. The father being indecisive as heck, picks *all* the names.
超冥 is a play on Chou Mei (long name), so I went with making the name long.
アルカナイカフォース・ドッチツカーズ Arukanaika Force Docchitsukaazu (Arcan-or-can’t Force – Ambiguous)
Level 7 LIGHT Fairy Effect Monster
【REQUIREMENT】 You can activate this by sending 1 monster with the same ATK and DEF from the hand to the GY.
【EFFECT】 Toss a coin. If it’s Heads, this card gains 1000 ATK until the end of the turn and destroy all face-up Level 8 or lower monsters your opponent controls. If it’s Tails, you take 1000 damage and all monsters you control are destroyed.
Note: This is like two or three dumb jokes shoved together.
The first is it’s obviously an Arcana Force XXI – The World ersatz.
Secondly is あるかないか which is like “Should I? Should I?”
The third is the second half of its name is a play on どっちつかず, which means basically “Undecided”, “Gray Area”, “Betwixt and Between”, “Ambigious”, or “Unclear”. etc.
迷い橋 Mayoi Bashi (Wavering Way)
Normal Trap Card
【REQUIREMENT】 You can activate this when a monster is Normal or Special Summoned face-up.
【EFFECT】 Choose 1 face-up monster you control with the same ATK/DEF and 1 face-up monster your opponent controls. During this turn, your monster gains 100 ATK times [The Level of your opponent’s chosen monster]. Then inflict damage to your opponent equal to [The difference between your monster’s ATK and your opponent’s monster’s ATK].
Note: This is a play on 迷い箸 which is literally “wavering chopsticks” but refers, as per all of Nishaw’s cards, to indecision due to hovering your chopsticks over which dish you want to pick from. Which is considered a faux pas when eating.
