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 Supplier|Supplier]] || 4 || EARTH || Rock|-| [[Koa'ki Meiru Powerhands only require 1 Normal Trap Card revealed).

Since most commonly used Synchro Monsters aren't DARK or LIGHT, Meiru Drago|Drago]]" and "[[Koa'ki Meirus tend to rely too much on Tornado or Ice in order to get rid of those (which are both useless against monsters like Meiru Doom|Doom]]") have effects focused on countering [[Stardust DragonLIGHT]]). Another huge synchro threat is Ally of Justice Catastor, and [[DARK]] monsters (which eliminates automaticly, any nonwere likely intended as "anti-meta" options against their contemporary LIGHT and DARK-Dark monster that does battle with it(without damage calculationbased meta Decks). In the other side, though, Four Level 4 EARTH Rock "Koa'ki Meiru" monsters ("[[MonarchsKoa'ki Meiru Overload|Overload]] are also a threat", since they do not rely on Special Summoning. A effective way to get rid of both is "[[[Compulsory Evacuation DeviceKoa'ki Meiru Guardian|Guardian]]. [[Remove from play]] Decks can remove ", "[[Iron Core of Koa'ki MeiruSandman|Sandman]]" and so you have to rely on your revealing effect.

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, but it gets destroyed, because you cannot add "[[Iron Core of cards can be played as staples in other Typing-focused Decks, or played as a single dedicated Deck. As a dedicated "Koa'ki Meiru]]" to your hand.

Obviously", the most important card needed in the deck is "[[Iron Core of Koa'ki MeiruUrnight]]", so having three in your and "[[DeckKoa'ki Meiru Supplier]] would be very helpful". Most of Aside from the "Rock Stun" "Koa'ki Meiru" monsters are used against [[Effect Monsters]], mostly [[DARK]] other relevant high-power (and [[LIGHT]] low-cost) "Koa'ki Meiru" monsters, since they are include the commonly used LIGHT and DARK hard counters "[[DeckKoa'ki Meiru Drago]]s (" and "[[Dark Armed DragonKoa'ki Meiru Doom]] decks", [[Lightsworns]], etc...). It is best to also have three of the card-destroying "[[Koa'ki Meiru BoulderIce]]" and "[[Koa'ki Meiru CrusaderTornado]]" in your Deck. , and the mass effect negation of "[[Koa'ki Meiru BoulderHydro Barrier]]" can search for . While "[[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 [[Draw Phase]]. in favor of other external enablers (and maintenance cost providers) like "[[Koa'ki Meiru SpeederAdamancipator]]" 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]]. Although [[Star Blast]] might seem a little wasteful seeing as most of the high level special summoning Koa'ki's are so few in number (i.e Maximus) and a cards like Rooklord's effect only work when they are normal summoned anyway 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]] (However as of the [[March 2010 Lists]] it will be limited to only one) 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 generally 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. 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, and allow for a good presence on the field. another good combo is using sandman, guardian, boulder and gigantes. 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.monsters.===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 "[[Shadow-Imprisoning MirrorRespect 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 "[[Light-Imprisoning MirrorVanity's Emptiness]]" are all effective against the deck.{{Archseries navbox}}{{ArchetypeNavboxArchseries navbox (Duel Links)}}[[Category:ArchetypeTCG and OCG archetypes]]
