"Steel Nucleus with Dragon Ruler Seeking Advice" Deck 2014

Playing

This is my first post. Any advice on construction, especially extras?
2014/5/4 Changed some construction. Yuushi and Tenki are introduced.
2014/7/16 He posted Koa'ki Meiru's Deck again, so please check it out.
I would consider putting Drago up anyway and keeping it.
There are many ways to put it on the field, including searching for Tempest and Vajra Core, and recruiting Urnite, so it's easy to set up.
Since the base RBI is high, there is no need to worry about destroying it in battle. However, it has no resistance to effect removal, so I try to keep one Steel Core in my hand so that I can activate 《Iron Core Luster》at any time. I want to insert the Holy Spear, but there is resistance because the RBI will go down...
If you have 2 or more Steel Cores in your hand, play Maximum. As mentioned earlier, this is a measure to leave the steel core in the hand. He's very costly and has a bad spot, but Ping is enough to get you into your hand, and if you want to keep it, it's going to be a decent deal. In fact, in a match with a friend (Infernity), I beat him desperately for about 5 or 6 turns, and if I had to, I could self-destruct and revive him with libide. Strong.
I will beat you anyway with that feeling. If you can't beat me, it's over.

Strength

If the opponent is mainly light and dark, Drago will become a monster. That's why he's teary-eyed like Infernity (laughs). Even if the opponent has other attributes as the main axis, it is possible to block General Synchro and Xyz to some extent and treat it as a mere demerit attacker.
Also, like The Six Samurai, Aces can also hit his light/dark deck.

Weakness

It is extremely weak against Skidre and Rock. Be very careful when fighting the Dark World.
I apologize for including Gigantes, but it's the same RBI as Koa'ki Meiru, so it's hard to do a suicide attack, and since it can't be used early in the game, it's slightly more prone to accidents. It's better than nothing, so I put it in.
Also, my friends get annoyed because of Drago. surely.

Customize

You can make a healthy Koaki Deck that is not annoying by removing dragons such as Drago and the Golden Chest and adding a few Varafar, Guardians, and general-purpose cards.
Also, as a different pattern, I think it will be even more annoying if you pile up pachycephalo like a meta beat...
