For exampleSecondarily, the archetype revolves around interactions with the Normal Spell "[[Iron Core of Koa'ki Meiru Drago]]'s" effect was designed especially to oppose .Almost every "Koa'ki Meiru" monster has a maintenance cost that must be performed during each of the player's [[Lightsworns|LightswornEnd Phase]]s, [[Dark Armed Return]], and [[Blackwings|Blackwing]] Decks for their [[Swarm]]ing capabilitiesotherwise they will destroy themselves. Against meta decks, "Koa'ki Meirus tend to Meiru" monsters typically have powerful [[Lockdown]] capabilities.

A number of those (which are both useless against "Koa'ki Meiru" monsters like (e.g. "[[Stardust DragonKoa'ki Meiru Drago|Drago]]). In the other side, though, " and "[[MonarchsKoa'ki Meiru Doom|Doom]] are also a threat, since they do not rely ") have effects focused on Special Summoning. A effective way to get rid of both is countering [[Compulsory Evacuation DeviceLIGHT]].and [[DARK]] monsters (which were likely intended as "anti-meta" options against their contemporary LIGHT and DARK-based meta Decks).Amazingly, one way to beat the KoaFour Level 4 EARTH Rock "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 " monsters ("[[Koa'ki Meiru or destroy the cardOverload|Overload]]", since they cannot "reveal" the card to you. Such cards include [[Respect PlayKoa'ki Meiru Guardian|Guardian]] and ", "[[Ceremonial Bell]Koa'ki Meiru Sandman|Sandman]. [[Remove from play]] Decks can remove ", "[[Iron Core of Koa'ki MeiruWall|Wall]]" and so you have to rely on your revealing ) also form a thematic sub-series with a single effect. It is best to have pattern: each of them can [[Imperial Iron Wallnegate]] an opponent's action (summoning a monster or [[Necrovalley]] in your [[Side Deck]]activating a card/effect of a card type) by tributing themselves. The most dangerous are [[hand destruction]] decks. If your hand becomes 0 too quickly, you have limited options. You can draw normally, hopefully getting a "Koa'ki Meiru monster" cards can be played as staples in other Typing-focused Decks, but it gets destroyed, because you cannot add or played as a single dedicated Deck. As a dedicated "[[Iron Core of Koa'ki Meiru]]" to your hand. AlsoDeck, most other the Deck primarily focuses on the Level 4 EARTH Rock "Koa'ki Meiru Spells " monsters due to their accessibility, power, and Traps need "synergy with [[Iron Core of Koa'ki MeiruRock]]support; they form a part of the popular " in your hand. [[Side DeckRock Stun]]ing " Deck.The Deck's main searchers are "[[Morphing JarDiamond Core of Koa'ki Meiru]]" and other draw cards can help. ==Playing Style== This , "[[DeckKoa'ki Meiru Urnight]] revolves around ", and "[[Anti-MetaKoa'ki Meiru Supplier]]". Obviously, Aside from the most important card needed in the deck is "[[Iron Core of Rock Stun" "Koa'ki Meiru]]"monsters, so having three in your [[Deck]] would be very helpful. Most of other relevant high-power (and low-cost) "Koa'ki Meiru" monsters include the monsters are used against LIGHT and DARK hard counters "[[Effect Monsters]], mostly [[DARKKoa'ki Meiru Drago]] " and "[[LIGHTKoa'ki Meiru Doom]] monsters", since they are the commonly used card-destroying "[[Deck]Koa'ki Meiru Ice]s ([[Dark Armed Dragon]] decks, [[Lightsworns]], etc...). It is best to also have three of " and "[[Koa'ki Meiru BoulderTornado]]" , and the mass effect negation of "[[Koa'ki Meiru CrusaderHydro Barrier]]" in your Deck. While "[[Koa'ki Meiru Boulder]]" can search for "[[Iron Core of Koa'ki Meiru]]" or a needed Koais central to the archetype'ki Meiru monsters playstyle, and there are multiple dedicated searchers for it (e.g. "[[Koa'ki Meiru CrusaderCore Transport Unit]]" can add "[[Iron Core of ), 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]]" from your [[Graveyard]]will typically try to downplay its importance, so you do not have to add it to your hand during the in favor of other external enablers (and maintenance cost providers) like "[[Draw PhaseAdamancipator]]" monsters. "[[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]]". While they are very strong against the current common [[Deck]]s, their weakness are [[Removed from play]] decks and [[Hand destruction]] decks. [[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 to have [[Imperial Iron Wall]] in your [[Side Deck]].  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 to help the anti meta abilities the trap [[Grave of the Super Ancient Organism]] making their monsters higher then LV 6 useless. If you play this card, you might also include [[Star Blast]], so your high-level monsters can temporarily get under the effect of [[Grave of the Super Ancient Organism]]. It would be wise for a serious Koa'ki Meiru Duelist who uses the cards [[Koa'ki Meiru Maximus]], [[Koa'ki Meiru Rooklord]] and [[Koa'ki Meiru Ghoulungulate]] to have 2 copies of [[Necroface]] in their deck, as these monsters remove cards from play, it would be good to get them shuffled back into your deck through [[Necroface]]'s effect. You can also play [[Return from the Different Dimension]], which, if timed appropriately, will generaly give you the game on a silver plate. 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.  ===Recommended Cardscards==={{Decklist|Deck

If the player is not careful and summons multiple "Koa'ki Meiru" monsters to the field without thought, it can easily blow up if one is not able to pay all the costs.** Additionally, cards such as "[[Respect Play]]" or "[[Ceremonial Bell]]" can eliminate the majority of the alternative maintenance costs by making it impossible to reveal any cards. In that case, one would be forced to rely on sending "Iron Core" to satisfy maintenance costs.* "Koa'ki Meiru" monsters are very reliant on the hand, therefore any form of "Hand Control" presents a big threat by being able to specifically remove assets essential to the Deck. Cards like "[[Card Destruction]]", "[[Mind Crush]]", "[[D.D. Designator]]" and "[[Trap Dustshoot]]" can completely disrupt the player's strategy.* Like many other decks, "Koa'ki Meiru" does not appreciate its Summons to be negated or blocked. "[[Solemn Warning]]", "[[Solemn Judgment]]", "[[Archlord Kristya]]", "[[Vanity's Fiend]]" or "[[Vanity's Emptiness]]" are all effective against the deck.{{Archseries navbox}}{{ArchetypeNavboxArchseries navbox (Duel Links)}}[[Category:ArchetypeTCG and OCG archetypes]]
