I am going to die from all these Dad Jokes.
ジョインテック・ブリキノサウルス Jointech Bliknosaurus
Level 7 EARTH Machine Effect Monster
ATK 2300
DEF 2000
[REQUIREMENT] You can send 1 card from your hand to the GY.
[EFFECT] Choose 1 face-up Attack Position monster your opponent controls and change it to face-up Defense Position. That monster loses 2000 DEF until the end of the turn.
Note: Blik is Dutch for Tin-Plate. The card is obviously playing on a Brachiosaurus.
タマタマガチャンス Tamatamagachance (Uneggspected Gachance/Uneggspected Jackpot)
Normal Spell Card
[REQUIREMENT] You can activate this by sending 1 face-up Level 1 Normal Monster you control to the GY.
[EFFECT] Send the top 3 cards of your Deck to the GY. If there was a Normal Monster among them, choose 1 Level 4 or lower Normal Monster in your GY and Special Summon it to your field face-up. If you Special Summoned “Eggbot” with this effect, you can Special Summon up to 2 “Eggbot” from your GY face-up.
Note: This card seems to be Tamatama (偶々) (i.e. Unexpected), Tamago (卵) (i.e. Egg), ガチャ (A capsule toy machine) and チャンス (Chance).
幻壊 is literally (Phantom/Mythic Destruction), but the premise appears to be Genkai, as in Limits/Frontier, and the jobs all seem to be Repairman work. But their Attribute and boss seems to lean to them being a Demolition Crew. So let’s go with Demolition to match Constructor unless you have a better idea. I will change this if flavor text gives a better idea.
幻壊兵ハイ・カンコウ Genkaihei High Kankou (Mythic Destruction Soldier High Kanko/Demolition Soldier High Kanko)
Level 4 FIRE Wyrm Normal Monster
ATK 1200
DEF 1500
Note: This card’s name is a play on 配管工 Haikankou (Plumber)
幻壊兵サカン・ヤサン Genkaihei Sakan Yasan (Mythic Destruction Soldier Sakan Yasan/Demolition Soldier Sakan Yasan)
Level 4 FIRE Wyrm Normal Monster
ATK 1300
DEF 800
Note: This card’s name is a play on 左官屋さん (Mr. Plasterer)
幻壊兵トビー・ショック Genkaihei Toby Shock (Mythic Destruction Soldier Toby Shock/Demolition Soldier Toby Shock)
Level 4 FIRE Wyrm Normal Monster
ATK 1500
DEF 0
Note: This card’s name is a play on 鳶職 Tobishoku (Scaffolding or Construction Worker)
幻壊竜 バクハムート Genkairyuu Bakuhamut (Mythic Destruction Dragon Bakuhamut/Demolition Dragon Blasthamut)
Level 8 FIRE Wyrm Effect Monster
ATK 2500
DEF 2000
[REQUIREMENT] If there is a face-up Field Spell Card on the field, you can activate this by sending 2 Wyrm Normal Monsters from your hand to the GY.
[EFFECT] Destroy all face-up monsters your opponent controls. Then, inflict 300 damage to your opponent x [The number of monsters destroyed by this effect].
Note: It’s a play on Bahamut, a mythical fish from pre-Islamic Arab folklore, that near as I can tell, due to Dungeons & Dragons, has become associated with dragons. The name is probably a corruption of Behemoth, one of the two legendary beasts in the Book of Job.
天守楼の幻壊 Tenshurou no Genkai (Demolition Frontier Defense Tower)
Field Spell Card
[REQUIREMENT] None
[EFFECT] While this card is face-up in a Field Zone, if a face-up Wyrm monster on the field is destroyed by battle, change the attacking non-Wyrm monster to face-up Defense Position.
Note: I’m pretty sure this card is playing on like, ‘frontier’ defense towers/castles in early Japan.
幻壊剣チクエディア Genkaiken Chikuedea (Mythic Destruction Sword Chikuedea/Demolition Sword Constructedea)
Equip Spell Card
[REQUIREMENT] You can equip this to 1 face-up Wyrm monster you control.
[EFFECT] The equipped monster gains 500 ATK. If there are 5 or more Wyrm Normal Monsters in your GY, the equipped monster gains 500 ATK.
Note: I’m pretty sure this is combining 築 (Construction) and Cinquedea, a type of sword.
