"Super Ancient Crystron (Crystron) Coelacanth" Deck 2018

Playing

Hold out with Crystron and fight back with Coelacanth.
If you draw Crystron and Undine, you can issue either 《White Aura Whale》or 《Crystron Quariongandrax》on your opponent's turn.
Also, you are lucky to have drawn 《Superancient Deepsea King Coelacanth》and 《Star Blast》.
You can suppress first and second attack one kill.
Even if you don't, you can aim for a one-kill if you can get away with Moby Dick or Grion Gund and use Coelacanth.
In case the first hand was an accident, I fully invested 《Moray of Greed》.

Sara Kiavis is linked to 500 offense and defence.
Sara Kivis (2100), Master Boy (2400), Sheila (3300), Moby Dick (3800).
Furthermore, the opponent's field is destroyed when Mokkei is summoned, and he is only in Defense Position, and since Mokkei attacks monsters twice and has piercing ability, the opponent's field is completely empty.
Also, if you add his ATK other than White Whale, he's 2100 + 2400 + 3300 = 7800, so if it's not enough for one kill, he can self-regenerate GY's Fishborg Launcher (elementary 200).
2100 + 2400 + 3300 + 700 = 8500 and one kill.
·others
Be aware of your priority when synchronizing your opponent's turn. In the opponent's turn, the opponent's side takes precedence for the first action in each phase. There are various ways to transfer priority, such as the opponent using his Normal Spell, Normal Summon, or using a monster effect, but let's use chains and priority to follow the rules and win.
Undine's GY manure is a cost, so it doesn't stop at Wailer.

Weakness

Weak against Urara. Weak to 《Called by the Grave》. Weak against Veiler.
It's also weak against Dark Law.
Due to the priority, if the black hole is used first, the field will be empty.
　
Moray eels can avoid accidents, but they still cause accidents.
It's okay to pull out the obstruction cards such as the Book of Moon, but I'm worried if the back is thin.
If you have a fish monster for a coelacanth combo in your hand, you're stuck. Let's fight with moray eels.

Customize

If you put in Halifiber, you can easily get Grion Gund, but I don't have Halifiber, so I can't use it. It's a wallet-friendly design.
As a synchro frame, it seems that the defense will be thicker if Cyframe Lord Zeta and Omega are included.
If you have 《Samurai Destroyer》, you can deal with Hope the Lightning, so you might want to include it.
Taking the plunge, he pulled out Harpie, his spells other than 《Star Blast》and put Recycler, etc.
Alternatively, you can use a Kaiju gimmick that works well with the Crystron.
