However " experimented and created the support card "[[Koa'ki Ring]]Meiru" and other anti-meta cards appear in [[Starstrike Blast]]Monsters.==Etymology==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 " is a combination of the monsters require a maintenance cost in the form words "Core", "Chimera" and "Mail", sometimes romanized as "Core Chimair" (a combination of sending an Iron Core to the grave or revealing words "Core" and "Chimera").==Design==The "Koa'ki Meiru" archetype consists of a monster plethora of the same type. There are exceptions such different creatures, featuring elementals, dragons, statues, warriors and many more and can overall be described as that a mishmash of [[Koaart styles. They don'ki Meiru Powerhand]]t really have any connection in design or color, where you must reveal a [[Normal Trap Cards|Normal Trap Card]]. except for the fact that all of the "Koa'ki Meirus are all [[EARTH]], [[WIND]], [[WATER]] " have the same mark (3 dragons) on some part of their body or on a weapon they use.==Playing style=="Koa'ki Meiru" is a [[[FIREstun]] attributes, rendering them immune to their own /[[control based effects which often affect [[LIGHT]] and Deck revolving around fulfilling its monsters' [[DARKmaintenance cost]] monsters. All of s in order to keep them on the "Koafield and apply their field-controlling effects. Secondarily, the archetype revolves around interactions with the Normal Spell "[[Iron Core of Koa'ki Meiru]]".Almost every " 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 " monster has a maintenance cost that must be performed during each of the player's [[End Phase]]s, otherwise they will destroy themselves. "Koa'ki Meiru Ghoulungulate]]. ==Playing Style==The theme was initially designed to bring down the dominating decks " monsters typically have a choice of over 2 banlists therefore centering around heavy control elements. Seeing as two actions for their maintenance costs; the meta was ''completelyoptions are typically sending an "Iron Core" from the player'' dominated by [[LIGHT]] and DARK deckss hand to the Graveyard, effects specifically targeted both Attributes therefore bringing about or revealing a specific Meta, Anti Meta theme. Because of card in the player's hand (typically a monster of their high [[ATK]], 11 Level 4 monsters from 1900 ATK, topping out at 3000 ([[Koa'ki Meiru Valafar]]same type), and the nature of the new support, the theme has taken a more aggressive approach with powerful beatdown elements, namely [[.{| class="wikitable mw-collapsible autocollapse" style="margin-left: auto; margin-right: auto; border: none; text-align: center" |+ {{nowrap|Koa'ki Meiru Rooklord]] and [[Monsters & Maintenance Costs}}! rowspan = 2 | Koa'ki Meiru Urnight]]. Generally speaking, there are two ways to use Koa'ki Meiru cards.

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 Sea Panther|Sea Panther]] || 4 || WATER || Sea Serpent| Reveal 1 WATER monster|-| [[Koa'ki Meiru Powerhands only require 1 Normal Trap Card revealed).

Most A number of "Koa'ki Meiru decks should focus on " monsters (e.g. "[[RockKoa'ki Meiru Drago|Drago]]-" and "[[TypeKoa'ki Meiru Doom|Doom]] and ") have effects focused on countering [[Beast-WarriorLIGHT]]-and [[TypeDARK]] monsters, using other Types according to the deck's main strategy(which were likely intended as "anti-meta" options against their contemporary LIGHT and DARK-based meta Decks). Often overlooked is the fact that you can use Four Level 4 EARTH Rock "[[Iron Core Armor]]" to substitute for the maintenance cost of Koa'Koa'ki Meiru " monsters. The main advantage of including ("[[Iron Core ArmorKoa'ki Meiru Overload|Overload]]" in your deck is that there exists plenty of support for , "[[Equip Spell CardsKoa'ki Meiru Guardian|Guardian]]. For example", using "[[Hidden ArmoryKoa'ki Meiru Sandman|Sandman]]" to search for , "[[Iron Core ArmorKoa'ki Meiru Wall|Wall]]" from your deck or graveyard may cause you to have one Koa'ki Meiru monster sent to your graveyard, which could be used to fuel the ) also form a thematic sub-series with a single effect pattern: each of "them can [[negate]] an opponent's action (summoning a monster or activating a card/effect of a card type) by tributing themselves."Koa'ki Meiru Ghoulungulate]]". [[Tradecards can be played as staples in other Typing-In]] can work well if using [[Beast King Barbaros]] to reveal for [[focused Decks, or played as a single dedicated Deck. As a dedicated "Koa'ki Meiru Urnight]] and [[" Deck, the Deck primarily focuses on the Level 4 EARTH Rock "Koa'ki Meiru Crusader]]. Other level 8 " monsters due to work with their accessibility, power, and synergy with [[Trade-InRock]] are support; they form a part of the popular "[[Koa'ki Meiru ValafarRock Stun]], and [[" Deck.The Deck's main searchers are "[[Diamond Core of Koa'ki Meiru Maximus]]. Maximus can also reveal for ", "[[Koa'ki Meiru DragoUrnight]] ", and Valafar is a strong beatstick that is immune to [[Torrential Tribute]], [[Bottomless Trap Hole"[[Koa'ki Meiru Supplier]]". Aside from the "Rock Stun" "Koa'ki Meiru" monsters, other relevant high-power (and low-cost) "Koa'ki Meiru" monsters include the LIGHT and DARK hard counters "[[Mirror ForceKoa'ki Meiru Drago]], " and "[[Call of Koa'ki Meiru Doom]]", the Hauntedcard-destroying "[[Koa'ki Meiru Ice]], " and "[[Core ReinforcementKoa'ki Meiru Tornado]]. It would be wise to include cards that return monsters ", and other cards to yours or your opponents hands. Copies the mass effect negation of "[[Compulsory Evacuation DeviceKoa'ki Meiru Hydro Barrier]] or [[Penguin Soldier]], for example, can both remove threats from the field or keep a ". While "Iron Core of Koa'ki Meiru alive for a turn" is central to the archetype's playstyle, or even using him for the maintenanceand there are multiple dedicated searchers for it (e.g.  Usual Anti-Meta tricks like "[[Grave of the Super Ancient OrganismCore Transport Unit]] or [[Royal Oppression]] works fairly well"), since Koa'ki Meirus can mantain a solid game even without Special Summoning.  Although most the fact that the card doesn't have any effects itself and is purely an enabler for certain specific cards means that more modern "Koa'ki Meiru monsters have difficulty staying on the field, a few " will typically try to downplay its importance, in favor of them work incredibly well together, sharing types, or common reveals that help ensure their survival on the field.  With the release of the other external enablers (and maintenance cost providers) like "[[Machine Emperors]] in the [[OCG]] the Koa'ki Meiru can evolve and expand their [[Anti-Meta]] to an anti-synchro level, the advantage of running the machine emperors lies in the self-destruction effects that is common among the koa'ki meiru and also that all of them except [[Machine Emperor Wisel Infinity]] are not [[DARK]] or [[LIGHT]] attribute rending them immune to the [[Anti-Meta]] effects shared among the archetype. while also combining with the effect of [[Iron Core Specimen Lab]] to search for key monsters such as [[Koa'ki Meiru Urnight]]. * [[Koa'ki Meiru Urnight]] 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.  * [[Koa'ki Meiru Wall]], [[Koa'ki Meiru Sandman]], [[Koa'ki Meiru Guardian]], [[Koa'ki Meiru Boulder]], [[Koa'ki Meiru Prototype]] and [[Gigantes]] can be extremely aggressive when combined, as well as controlling the field and hand.  * [[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]] also work together, usually on its own deck revolving around [[Evil Hero Dark Gaia]] and [[Dark Fusion]]. * [[Koa'ki Meiru Speeder]] can null the costs for [[Koa'ki Meiru Tornado]] and [[Koa'ki Meiru Hydro Barrier]], as well as working with [[Koa'ki Meiru Powerhand]] due to their high ATK and DEF and low Levels. * [[Koa'ki Meiru Ghoulungulate]] has a protection effect, which can be achieved easily by building up a good graveyard size with [[Iron Core Specimen Lab]] and [[Koa'ki Meiru Urnight]]. [[Koa'ki Meiru Ghoulungulate]] can easily be brought out with [[Pyramid Turtle]]'s effect, and keeps a good Tribute fodder for [[Koa'ki Meiru Rooklord]]. Since both [[Remove from Play]], [[Burial from a Different Dimension]], and [[Return from the Different Dimension]] can be very powerful. Finally, a few cards have a usually heavy cost of discarding a [[Spell Card]] from your hand (like [[Summoner Monk]], [[Cursed Seal of the Forbidden Spell]] and [[Chiron the Mage]]), but Koa'ki Meiru decks can recycle the [[Iron Core of Koa'ki Meiru]] as long as they want to, making these much more consistent than any other deck. ===Recommended Cards=== ====[[Monster Cards]]====[[Rock]](For [[Koa'ki Meiru Guardian]]/[[Koa'ki Meiru Sandman]]/[[Koa'ki Meiru Wall]])* [[Gigantes]]* [[Neo-Spacian Grand Mole]]* [[Legendary Jujitsu Master]] [[Beast-Warrior]] (For [[Koa'ki Meiru Crusader]]/[[Koa'ki Meiru Urnight]])* [[Beast King Barbaros]]* [[Chiron the Mage]]* [[Pitch-Black Warwolf]] [[Warrior]] (For [[Koa'ki Meiru Bergzak]]/[[Koa'ki Meiru Rooklord]]/[[Koa'ki Meiru War Arms]])* [[D.D.
