"Use coelacanth to remodel the area or interfere with the first 7" Deck 2021

Playing

It was supposed to be a deck that hits 《Eria the Water Charmer, Gentle》with 3 《Armory Arm》.
Edit: I changed the construction a little. I'm going to use two Dugales materials...

Strength

The expected combo is
①《Lifeless Leaffish》effect. Send Superancient Deepsea King Coelacanth to his GY.
② Xyz Summon 《Number 60: Dugares the Timeless》together with Deadleaf.
③《Number 60: Dugares the Timeless》(Extra Monster Zone) effect. Revived 《Superancient Deepsea King Coelacanth》.
④ 《Superancient Deepsea King Coelacanth》effect. Special Summon the two 《Oyster Meister》, 《Gluttonous Reptolphin Greethys》, and 《Fishborg Launcher》.
⑤ Use 《Number 60: Dugares the Timeless》and 《Fishborg Launcher》to link summon 《Crystron Halqifibrax》. Special Summon Jet Synchron with effect.
⑤ Synchro summons "Armory Arm" with "Jet Synchron" and "Oyster Meister". Oyster token generation.
⑥ Use the Oyster Token and "Gluttonous Reptolphin Greethys" to synchro summon "Armory Arm".
⑦ Self-revival with 《Jet Synchron》effect.
⑧ Synchro summons "Armory Arm" with "Jet Synchron" and "Oyster Meister". Oyster token generation.
⑨ Link Summon 《Eria the Water Charmer, Gentle》with Oyster Token and 《Crystron Halqifibrax》.
⑩ Equip 《Eria the Water Charmer, Gentle》with three 《Armory Arm》.
By doing so, the ultimate Elia-chan, who has an ATK of 4850 and deals damage three times the ATK of the monster destroyed in battle, will explode. Attacking a monster with ATK 1575 or higher will give you a one-shot kill. However, with this alone, there was nothing to do in advance, and there was still room for extras.
①《Lifeless Leaffish》effect. Send 《Superancient Deepsea King Coelacanth》to GY.
② Xyz Summon 《Number 60: Dugares the Timeless》together with Deadleaf.
③ 《Number 60: Dugares the Timeless》(Main Monster Zone) effect. Revived 《Superancient Deepsea King Coelacanth》.
④ 《Superancient Deepsea King Coelacanth》effect. Special Summon two monsters, including 《Fishborg Launcher》and ☆4 Fish.
⑤ Link Summon 《Crystron Halqifibrax》with Fish and 《Fishborg Launcher》.
⑥ 《Gluttonous Reptolphin Greethys》Special Summon with the effect of 《Crystron Halqifibrax》. 《Fishborg Launcher》was also revived by its own effect.
⑦ Link Summon Apollousa, Bow of the Goddess with 4 bodies: Halifair, Coelacanth, Dugales, and Launcher.
⑧ Synchro summons 《White Aura Monoceros》with 《Gluttonous Reptolphin Greethys》and ☆4 Fish. The effect revived "Superancient Deepsea King Coelacanth".
⑨ 《Superancient Deepsea King Coelacanth》effect. Special Summon 3 monsters, including 2 ☆4 Fish.
⑩ Xyz Summon 《Mermail Abyssgaios》with 《White Aura Monoceros》and 《Superancient Deepsea King Coelacanth》.
⑪ Xyz summon Bahamut Shark with two ☆4 Fishes. Special Summon Toadally Awesome with effect.
⑫ Link Summon 《Predaplant Verte Anaconda》with 《Bahamut Shark》and the remaining Fish monster.
⑬《Predaplant Verte Anaconda》effect. 《Fusion Destiny》dropped into GY and fusion summoned 《Destiny HERO - Destroyer Phoenix Enforcer》.
By doing so, I was able to negate monster effects 5 times with the 4 materials Apollo Usa and Gaio Abyss, negate anything with Mochi once, and set up a 7-interference that destroyed Destroy Phoenix Guy's Furice.
Reasons for adopting cards whose names are not listed below
・《Beautunaful Princess》
A card that becomes 《Lifeless Leaffish》. Also adopted 《Piri Reis Map》and 《One for One》to bring. As a result, we have 10 dead leaves.
・《Silent Angler》
Rank 4 manufacturing machine #1. It becomes 《Number 60: Dugares the Timeless》with the deadleaf. Also for the bullets of Coelacanth's recruit effect.
・《Prediction GUY》
Rank 4 manufacturing machine 2. By playing 《7 Colored Fish》, Xyz materials are created. ...Gagakigo is a more suitable deck for him who intends to fight in the area, but I prioritized the fact that it is Fish.
・《Tenyi Spirit - Shthana》
Rank 4 manufacturing machine 3. Originally adopted 《Supreme King Dragon Darkwurm》is his DARK, so if he falls to GY due to the effect of 《Number 60: Dugares the Timeless》, it will hinder the self-resurrection effect of 《Fishborg Launcher》, so it was changed.
・《White・《Hinotama Soul》Ray》
Rank 4 manufacturing machine 4. Since the hand cost is high, use the number sparingly. Water level 4 with self-SS effect, most of them are limited cards that hinder later development.
・《Monster Reborn》, 《World Legacy Succession》
Revive Spell. When the effect of Coelacanth is stopped, you can heal only once by forming a link area with Dugales and reviving with these. It's thin because it's only 4 pieces, but...
・《Gozen Match》
If you can activate it when 《Number 4: Stealth Kragen》is present, you can set a nasty lock. If I hold it, I'm going to put out Jellyfish Senpai instead of Bahasha.

Weakness

Even though there are 10 cards each, the probability of getting both in the first move is only about 60%, and it lacks stability.
Also, since it relies heavily on 《Superancient Deepsea King Coelacanth》and you can't fight well with any other method, it will be a problem if you can stop it here. It's also weak against 《Nibiru, the Primal Being》.
Since 《Piri Reis Map》, 《Predaplant Verte Anaconda》and cards that reduce his LP are conspicuous, it seems quite difficult for him to directly target his LP.
There are 7 more obstructions, but 5 of them can only stop monster effects. If 《Toadally Awesome》is managed somehow, even 《Special Hurricane》will wipe it out.

Customize

If you remove all the cards for 《Eria the Water Charmer, Gentle》and 《Armory Arm》, you will have several main extras. I won't do it, but if I put a general-purpose card in that frame, I think the degree of perfection as a deck that moves Superancient Deepsea King Coelacanth will go up.
Also, 《Oyster Meister》and 《Gluttonous Reptolphin Greethys》are included in the minimum required number. If you're the type who tends to skip Orion, it might be safer to increase the number of cards a little.
The recently trending business trip trio of 《Cupid Pitch》+ 《Nemeses Corridor》+ 《Thunder Dragon Colossus》might also be good. You can use it if you bite once when you put out three 《Armory Arm》. You won't have any Oyster Tokens for that, but Coelacanth can't attack anyway, so there's almost no problem using it as an area material.
If you remove Emeral and Kurage-senpai, you will have extra space, and if you remove 《Gozen Match》, you will have space in the main, so you can increase 《Oyster Meister》and 《Gluttonous Reptolphin Greethys》. Since Deadleaf can be removed with the 2nd effect, it also fulfills his Special Summon condition in the Corridor.
Since the board when the link area is displayed is 3 bodies, Halifair, Coelacanth, and Oyster Token, if you convert two of these into 《Shinobi Insect Hagakuremino》《Knightmare Phoenix》《Cross-Sheep》《Security Dragon》Earth and LIGHT monsters can be prepared. It eats one frame extra, but it is also possible to change the area to other link charmers.
... It's a charm that it's stronger to put out 《Accesscode Talker》instead of Link Charmer, with around 《Knightmare Unicorn》.
