Koa'ki Meiru Traptrix: deck recipe

Duel Links Breaking News
30th Mini Box: Voltage of the Metal
update 03/01/2019


This is an Anti-Meta Deck that takes advantage of powerful Trap Cards such as Void Trap Hole and Treacherous Trap Hole in order to disrupt the opponent’s plays while slowly depleting their resources. Traptrix Atrax and Traptrix Dionaea are able to facilitate the use of your Trap Cards, whereas Koa'ki Meiru Beetle is used to deal with popular decks such as Masked HERO and Blue-Eyes.

Set Skill

[Skill] descriptionUser
Endless Trap Hell
Can be used when you have 3 trap cards in the Graveyard. 1 random Trap Card in your Graveyard is added to your hand. Then, shuffle 1 random Trap Card in your Graveyard into your Deck. This skill can only be used once per Duel.

How to Use

Koa'ki Meiru Beetle

Koa'ki Meiru Beetle switches into Defense Position any LIGHT or DARK monster that is Special Summoned on either side of the field. Masked HERO Anki, Cosmo Brain, Blue-Eyes White Dragon, Dragon Spirit of White, Armades, Keeper of Boundaries, Silent Magician and Silent Magician LV8 are all fairly common monsters in the current meta and Koa'ki Meiru Beetle alone is enough to force your opponent to wait for their next turn before they are able to switch them back into Attack Position and attack you with them.

You can add Koa'ki Meiru Beetle from your Deck to your hand with Diamond Core of Koa'ki Meiru and then either banish the Spell Card from your Graveyard or, during the End Phase, reveal another Koa'ki Meiru Beetle or a Traptrix Atrax from your hand to prevent it from being destroyed by its own effect.

By Normal Summoning Koa'ki Meiru Beetle on Turn 1, you will likely able to prevent an OTK from a Masked HERO or a Blue-Eyes Deck on Turn 2.

Tratrix Atrax

Traptrix Atrax allows you to activate “Hole” Normal Trap cards directly from your hand while also preventing the opponent from negating the activation or effects of Normal Trap Cards activated on your side of the field, which is particularly relevant at the moment because of Koa'ki Meiru Sandman.

Traptrix Atrax is able to render cards like Hey, Trunade!, Galaxy Cyclone and Cosmic Cyclone, which are commonly used to deal with the opponent’s backrow, completely useless, turning Treacherous Trap Hole, Void Trap Hole and Floodgate Trap Hole into Hand Traps.

Traptrix Dionaea

When Normal Summoned, Traptrix Dionaea allows you to target a “Traptrix” monster in your Graveyard and Special Summon it in Defense Position. Since the effect does not state otherwise, you can Special Summon another copy of Traptrix Dionaea from your Graveyard via this effect.

Once per turn, when Traptrix Dionaea is Special Summoned, it allows you to target a “Hole” Normal Trap Card in your Graveyard and Set it, but you have to banish it during the End Phase of your next turn if it’s still on the field. Thanks to this effect, you are able to use Treacherous Trap Hole multiple times during the same Duel without even activating Endless Trap Hell.

Void Trap Hole

Void Trap Hole is a great answer to Masked HERO Anki, Cosmo Brain, Koa'ki Meiru Maximus and many other monsters that are very popular in the current meta.

This Trap Card can negate the effects of an opponent’s monster with 2000 ATK or more that was Special Summoned and then destroy it; Diamond Core of Koa'ki Meiru obviously provides protection against the second part of this effect, but you would still be safe from Maximus’ effect after activating this card.

Endless Trap Hell
Can be used when you have 3 trap cards in the Graveyard. 1 random Trap Card in your Graveyard is added to your hand. Then, shuffle 1 random Trap Card in your Graveyard into your Deck. This skill can only be used once per Duel.

Endless Trap Hell can be used to prevent you from deking out before your opponent; it’s generally a great Skill with any deck that likes to run a lot of Trap Cards and it functions very well with Treacherous Trap Hole in particular.


  • The deck feels pretty slow and may take some time to finish off most opponents.
  • If you are not able to prevent a high ATK monster from being Summoned, you are likely going to struggle dealing with it, unless Treacherous Trap Hole or Wall of Disruption are available.


Has anybody tried this out? Seems interesting.
Interesting deck idea indeed.

I'd personally go with just 2 WOD and replace the third copy with Cross-Sword Beetle, though.

That way, Atrax and KM Beetle can do some damage to defense position monsters, giving more pressure to the opponent, not to mention it's another Insect monster to reveal for KM Beetle's maintenance cost, in case you don't have the space to summon it.

Also because I usually feel 2 WOD is more than enough.
Interesting combination, I tried it and it can be somewhat consistent.
