"Cthulhu ~The duelist who fell into madness~" Deck 2015

Playing

I'm looking forward to the next extra pack. I don't understand why Mr. Konmai always separates the recording cards for the overseas version and the Japanese version every time. That's why I tried to build [Cthulhu]. Well, it's just a solitaire one-shot deck when you have all the parts. The spinning side was Deck, the epitome of fun.
Cards not released in Japan are substitutes. It looks like this.
《Polymerization》→《Fusion Substitute》
《Herald of the Arc Light》→《Old Entity Cthugua》
《DDD Sniper King Teru》→《Outer Entity Azathot》
The parts necessary for one shot kill are as follows.
《Synchro Fusionist》+ 《Expected GUY》+ Resurrection card (Either Explosion, Refusion, or 《Monster Reborn》. Super fusion is also possible)
or
《Synchro Fusionist》+ 《Brilliant Fusion》+ Resurrection Card
《Em Trick Crown》and 《H・C Thousand Blade》are OK for the resurrection card frame.
1. Expected GUY activation. Special Summon Galaxy Serpent from your Deck or hand.
2. Change 《Synchro Fusionist》to Normal Summon.
3. Synchro Summon 《Old Entity Cthugua》A with Serpent + Fusionist. Search for 《Instant Fusion》with Fusionist.
4. Simple activation. 《Elder Entity Norden》Special Summon A and revive Fusionist.
5. Xyz Summon 《Daigusto Emeral》A with Togua A + Norden A. 1 draw.
6. Activate Emeral A effect. Pay Norden to revive the Serpent.
7. Synchro Summon Kutogua B with Serpent + Fusionist. search with fusionist effect. The effect of Kutogua B does not activate.
8. Activate refusion. Revive Norden A from GY. Revive Fusionist with Norden A effect.
9. Xyz Summon Emeral B with Norden A + Kutogua B. 1 draw.
10.Emeral B effect activated. Pay Norden to revive the Serpent.
11. Synchro Summon Kutogua C with Serpent + Fusionist. Search for "Fusion Substitute" with the Fusionist effect. Ctogua effect does not activate.
12. Activate Fusion Substitute. Fusion summons Norden B by fusing Emeral AB. Revive Ctogua A with Norden B effect.
13. Xyz Summon Outer Entity Nyarla with Norden B + Kutogua A. Xyz summon Outer Entity Azathot using Niarra as a material. Completely removed with Azathoth effect.
Up to this point, it's the same route, but depending on the type of cards in your hand, the subsequent development and the ORU that you pay with Azathoth will change.
Re-fusion, possession of 《Monster Reborn》→ ORU to pay with Azathoth is Norden B. Re-fusion activated. Revive Norden A and revive Kutogua B.
With this, 2400+2000+2200+2200=8800 is one kill.
《Rekindling》Possession → ORU to pay with Azathoth is Togua C. Revived 2 Kutoguas from her GY with an explosion.
Even this is 2400 + 2200 + 2200 + 2200 = 9000 one kill.
ORU to pay with super fusion possession → Azathoth is Norden B. After removing all of them, GY's Fusion Substitute effect recovered Norden A to Extara and transitioned to the Battle Phase. After attacking Azathoth and Kutogua, use Super Fusion to fuse the two and fusion summon Norden A. The effect revives Kutogua A and pursues it.
Now 2400+2200+2000+2200=8800 is one kill.
Trikura, blade possession → Use the effect of "discard any number of cards in your hand and raise the rank by the amount discarded" when summoning Niarra's X, crown + blade to his GY. He Xyz Summons Gagaga Samurai with the movement of the Crown Blade. Activate the effect to enter the battle phase.
Now you can get one kill at 1900+1900+2400+2200=8400.
Brilliant Fusion In the case of initial action
Activate Brilliant Fusion. Send Lazuli + Serpent to GY to fusion summon Seraphi. All you have to do is increase your summoning authority with Seraphy's effect and summon Serpent and Fusionist.

Strength

In short, if you have Fusionist and Serpent, you can draw 3 cards in the process of development, so if you draw a resurrection card there, you win. If Azathoth descends, your opponent will not be able to use monster effects that turn, so you can get one kill by slashing all the cards that stop attacks, such as Goze, Trago, Fader, and Scarecrow.

Weakness

It can not be deployed unless the fusionist and serpent are aligned. Especially the fusionist. Nothing will start until this guy comes. There aren't many slots for general-purpose cards in Extras, so once you're outnumbered, it's hard to come back.
Also, due to the nature of the no-lap, we can't control the opponent's deployment, and if the opponent continues to stop the deployment due to a lot of backing, we will lose.

Customize

If you have any good ideas for extras, please let me know. Of course, advice from the main Deck is also welcome.
