'''Koa'ki Meiru''', sometimes romanized as '''Core Chimail''' (a combination of the words "Core", "Chimera", and "Mail", a synonym for armour) is a theme from [[Raging Battle]], [[Ancient Prophecy]], [[Stardust Overdrive]], [[Absolute Powerforce]], and [[The Shining Darkness]].  However the support card "[[Koa'ki Ring]]" and other anti-meta cards appear in [[Starstrike Blast]].

The majority of their effects center around manipulating the [[Iron Core of Koa'ki Meiru]] or revealing one in hand to activate an effect. The strongest of the monsters require a maintenance cost in the form of sending an Iron Core to the grave or revealing a monster of the same type. There are exceptions such as that of [[Koa'ki Meiru Powerhand]], where you must reveal a [[Normal Trap Cards|Normal Trap Card]].

Koa'ki Meirus are all [[EARTH]], [[WIND]], [[WATER]] or [[FIRE]] attributes, rendering them immune to their own control based effects which often affect [[LIGHT]] and [[DARK]] monsters. All of the "Koa'ki Meiru" have the same mark (3 dragons) on some part of their body or on a weapon they have. Also, many Koa'ki Meiru and related cards' artwork uses yellow, orange, and red, except [[Koa'ki Meiru Ghoulungulate]].

==Playing Style==
The theme was initially designed to bring down the dominating decks of over 2 banlists therefore centering around heavy control elements. Seeing as the meta was ''completely'' dominated by LIGHT and DARK decks, effects specifically targeted both Attributes therefore bringing about a specific Meta, Anti Meta theme. Because of their high [[ATK]], 11 lvl 4 monsters from 1900 ATK, topping out at 3000 ([[Koa'ki Meiru Valafar]]), and the nature of the new support, the theme has taken a more aggressive approach with powerful beatdown elements, namely [[Koa'ki Meiru Rooklord]] and [[Koa'ki Meiru Urnight]].

Generally speaking, there are two ways to use Koa'ki Meiru cards. The most obvious is to simply use a dedicated deck; the other being to use individual Koa'ki Meiru monsters as a supplement to Type specific decks of their type, giving an [[Anti-Meta]], controlling aspect to it as well asbeing able to maintain it through the alternative maintenance cost; for example, using [[Koa'ki Meiru Drago]] in a Dragon type deck as seen in Disaster Dragon builds.

In order to run a Koa'ki Meiru deck, no matter the style, you'll need multiple ways to retrieve the [[Iron Core of Koa'ki Meiru]] from your deck and graveyard such as [[Koa'ki Meiru Boulder]], [[Koa'ki Meiru Crusader]], and [[Core Transport Unit]]. [[Iron Core Immediate Disposal]] is also nice mid game, after building up resources in hand. You must also be wary of keeping more on field than you can maintain. Your field should max out at 2 Koa'Ki Meiru's requiring maintenance with multiple Cores in play as well as an alternative cost ready in hand.

Beatdown uses a different lineup, using a minimum of control but only the best in the form of Rooklord and Drago. The main attackers being [[Koa'ki Meiru Bergzak]],[[Koa'ki Meiru Powerhand]] and [[Koa'ki Meiru Rooklord]]. With the addition of [[Koa'ki Meiru Urnight]] from [[Absolute Powerforce]], you gain a swarm/toolbox element. [[Koa'ki Meiru Ghoulungulate]] is nice protection but your tribute fodder is best used on Rooklord. S/t protection is a better option. 

You can also play a RFG Koa'ki Meiru deck. Ghoulungulate can protect your monsters while setting you up for [[Return from the Different Dimension]]. Milling elements are recommended to load your grave. The set up takes time so you can use Royal Oppression as you aren't in any rush. Cyber Valley is also a great asset to the deck.

In an ever evolving meta, we are straying away from old habits. As we speak, Lightsworn have fallen to tier 2, Infernity are losing ground because of inexperience, Herald decks are seeing less and less play for God knows why, Gladiator Beasts have taken the place of Frognarchs and X-Sabers reign supreme. Koa'ki Meiru's have lost their place in the Anti Meta and stand to survive as a Beatdown deck with favorable matchups to the occasional Herald deck and the more common Infernity player.

==Weaknesses==
Because [[Iron Core of Koa'ki Meiru]] may often be in the graveyard, it is vulnerable to cards that can remove it from play, such as [[Gladiator Beast Retiari]], and [[Macro Cosmos]]. Also, having multiple Koa'ki Meiru monsters on the field at once can be extremely dangerous, as each one would require you to reveal or discard a card from your hand at the End Phase; leaving hand and field advantage very hard to maintain, unless multiple copies are used (for example, 3 Koa'ki Meiru Powerhands only require 1 Normal Trap Card revealed). Koa'ki Meirus are very reliant on the hand and so cards like [[Card Destruction]], [[Mind Crush]] or [[D.D. Designator]] can completely disrupt the player's strategy, and cards like [[Trap Dustshoot]] or even [[Des Koala]] deal serious damage.

Amazingly, one way to beat the Koa'ki Meiru format is to have the opponent permanently reveal their hand to you on their turns in order to make them either discard an Iron Core of Koa'ki Meiru or destroy the card, since they cannot "reveal" the card to you. Such cards include [[Respect Play]] and [[Ceremonial Bell]]. [[Remove from play]] Decks can remove "[[Iron Core of Koa'ki Meiru]]" and so you have to rely on your revealing effect. It is best a good idea to have [[Necrovalley]] and a [[Burial from a Different Dimension]] in your [[Side Deck]]. 

Hand Control decks present the biggest threat by being able to specifically remove assests essential to the deck.

==Playing Tips==

This deck revolves around [[Anti-Meta]].  Obviously, the most important card needed in the deck is "[[Iron Core of Koa'ki Meiru]]", so having three in your deck is a must.  Most of the monsters are used against [[Effect Monsters]], mostly [[DARK]] and [[LIGHT]] monsters, since they are the commonly used decks ([[Infernities]], [[Lightsworns]], [[Blackwings]] etc...).  It is best to also have three of "[[Koa'ki Meiru Boulder]]" and "[[Koa'ki Meiru Crusader]]" in your Deck.  "[[Koa'ki Meiru Boulder]]" can search for "[[Iron Core of Koa'ki Meiru]]" or a needed Koa'ki Meiru monster.  "[[Koa'ki Meiru Crusader]]" can add "[[Iron Core of Koa'ki Meiru]]" from your [[Graveyard]], so you do not have to add it to your hand during the [[Draw Phase]].  "[[Koa'ki Meiru Speeder]]" has a high Defense and if you draw "[[Iron Core of Koa'ki Meiru]]" you can draw another card. While usually this proves itself quite situational, you can abuse the effects of "[[Koa'ki Meiru Hydro Barrier]]" and "[[Koa'ki Meiru Tornado]]".

[[Trade-In]] can work well if using [[Beast King Barbaros]] to reveal for [[Koa'ki Meiru Urnight]] and [[Koa'ki Meiru Crusader]]. Other level 8 monsters to work with [[Trade-In]] are [[Koa'ki Meiru Valafar]], and [[Koa'ki Meiru Maximus]]. Maximus can also reveal for [[Koa'ki Meiru Drago]] and Valafar is a strong beatstick that is immune to [[Torrential Tribute]], [[Bottomless Trap Hole]], [[Mirror Force]], [[Call of the Haunted]], and [[Core Reinforcement]].
Though [[Necrovalley]] and the [[Gravekeepers]] may hinder a Koa'ki Meiru's playing style and vice versa they can actually help one another especially if you have [[Gravekeeper's Chief]], which takes care of the out of play problem. 

However it would be wise to include cards that return monsters and other cards to yours or your opponents hands. Such as multiple copies of [[Compulsory Evacuation Device]] or [[Penguin Soldier]]. This way if you cant reveal the correct type of card or discard an Iron Core you can return them to your hand instead or in the case of [[Penguin Soldier]] return one monster your opponent has and your own. Another good card to add in case of a remove from play type opponent use the trap card [[Imperial Iron Wall]] allowing you to keep your cards.

Another trick you might want to consider is the trap [[Grave of the Super Ancient Organism]], which makes the opponents LV 6 or higher monsters useless.LV 5 [[Koa'ki Meiru Ghoulungulate]] works well with the trap and is search-able with [[Pyramid Turtle]]. [[Royal Oppression]] is also another trap that works well in this deck since your opponent can't negate this special summon.  

Also a player might want to include [[Evil Hero Dark Gaia]] and [[Dark Fusion]] since there is a fairly powerful amount of [[Fiend]]
and [[Rock]] type Koa'ki Meiru monsters such as [[Koa'ki Meiru Valafar]] and [[Koa'ki Meiru Guardian]] which would make for a 4900 ATK monster.

Although most Koa'ki Meiru monsters have difficulty staying on the field, a few of them work incredibly well together, sharing types, or common reveals that help ensure their survival on the field. 

* [[Koa'ki Meiru Urknight]] and [[Koa'ki Meiru Crusader]] share the [[Beast-Warrior]] type, and reveal requirement, while allowing for a good presence on the field and card advantage. 

* Another good combo is using [[Koa'ki Meiru Sandman]], [[Koa'ki Meiru Guardian]], [[Koa'ki Meiru Boulder]], [[Koa'ki Meiru Prototype]] and [[Gigantes]]. 

*[[Koa'ki Meiru Maximus]] can be used as the reveal cost for [[Koa'ki Meiru Drago]]. Drago's effect serves as disruption, while you gather [[Iron Core of Koa'ki Meiru]] for Maximus's final push for game. 

*[[Koa'ki Meiru Doom]] and [[Koa'ki Meiru Valafar]] are also work together, but are often less effective. 


[[Core Overclock]] can boost these monsters up 1500 attack points, making strong synchro monsters less of a hassle. Combined with [[Koa'ki Meiru Ghoulungulate]] and his removal effect, maintaining the field can be achieved easily by building up a good graveyard size with [[Iron Core Specimen Lab]].  [[Koa'ki Meiru Ghoulungulate]] can easily be brought out with [[Pyramid Turtle]]'s effect, allowing him to quickly and easily set up a wall, protecting all of your Koa'ki Meiru monster's from being destroyed, while you focus on summoning stronger monsters like [[Koa'ki Meiru Rooklord]] or [[Koa'ki Meiru Valafar]] This combined with [[Koa'ki Meiru Urknight]]'s ability to special summon (preferably other Koa'ki Meiru monsters to fill the graveyard up for [[Koa'ki Meiru Ghoulungulate]]) can lead to a quickly controlled field, while adding some powerful beat-sticks and controlling effects to the field. Some cards that support this strategy well are [[Foolish Burial]], [[Burial from a Different Dimension]], and [[Return from the Different Dimension]] to compensate for the loss of graveyard presence and to counter a removal of an [[Iron Core of Koa'ki Meiru]] from play, which would otherwise cripple the deck.

You can also [[Summon]] a "[[Summoner Monk]]" if you have more than 1 "[[Iron Core of Koa'ki Meiru]]" in your [[hand]]. With its effect, you can discard 1 "[[Iron Core of Koa'ki Meiru]]" to [[Summon]] a [[Level]] 4 "Koa'ki Meiru" monster. Even though it can't [[attack]] for this turn, you can either send "[[Iron Core of Koa'ki Meiru]]" to the [[Graveyard]] or reveal for the [[Special Summon]]ed "Koaki Meiru" monster to survive, or by activating a "[[Double Summon]]" or an"[[Ultimate Offering]]" (if "[[Summoner Monk]]" was [[Summon]] in this turn), you can [[Tribute]] the [[Special Summon]]ed "Koa'ki Meiru" monster to [[Tribute Summon]] a "[[Koa'ki Meiru Valafar]]" or a "[[Koa'ki Meiru Rooklord]]".

Since you are constantly discarding [[Iron Core of Koa'ki Meiru]] another great card to have in this deck is [[Forced Requisition]]. This will help deplete your opponents hand very quickly. This helps maintain hand advantage over your opponent, especially if your opponent is not expecting it.
