"A steel core that steals the earth" Deck 2013

Playing

Among the "Koa'ki Meiru", there are three Rock "Koa'ki Meiru" that specialize in the ability to suppress 《effects》, while obstructing the opponent's actions with "Wall", "Sandman", and "Guardian". Deck that beats down.
These 3 "Koa'ki Meiru" have a release cost, so they can be activated without being affected by 《Skill Drain》. You can interfere with your opponent's actions, and you can easily act as you wish, so it's very easy to get around.
"Koa'ki Meiru" in this deck are all level 4, so he has a low ATK, but with Core Overclock, it doesn't matter.

Strength

In addition to the above three, "Koa'ki Meiru" also has "Power Hand", "Beetle" from the light/dark meta, and "Rock" from the "Steel Core" search. Apart from "Rock", if you can make full use of these 5 "Koa'ki Meiru", you can do a fairly wide range of metas.
In addition, 《Block Golem》is used for Xyz. Since the cost of the effect is Release, it is not affected by 《Skill Drain》, and this Deck with a lot of Rock has plenty of personnel. Various Xyz Monsters can be deployed depending on the situation.

Weakness

Basically, you can fight stably, but there are times when the equipped 《Macro Cosmos》will have a bad effect on your army.
When "Koa'ki Meiru" is released as an effect, it goes to the exclusion zone as it is, so you can't use it for 《Core Reinforcement》etc., so the timing of its use is quite important.

Customize

I think it would be possible to remove 《Macro Cosmos》and insert other removal cards, or use 《Gozen Match》and 《Battle of the Elements》since all the monsters in the Deck are EARTH.
