Ultimate Yobinion! Water Darkness Nature Malulu Deck [Water Darkness Nature Malulu]

Official main image

1. Deck Overview

A "big mana" control deck that ramps up mana and then slams down powerful cards. It is based on the control deck [Water Darkness Nature Malulu] that appeared in the competitive environment around autumn 2024, and it stands head and shoulders above the rest of these 25 decks as a top-tier "winning" deck.

Its greatest strength is the overwhelming resource generation of Yobinion Malulu and Deddam, Disaster. While many decks are still doing their first mana boost on turn 3, this deck can reach 6 mana as early as turn 3. It crushes the opponent with this resource gap. It also has a wide range of customization options, making it suitable for players just starting out.

2. How to Win

The flow is: ramp mana → widen the resource gap with "Yobinion" → take control with high-cost finishers.

The core is the so-called "2-4-7" golden curve. Mana boost on turn 2, Yobinion Malulu on turn 3, and by the next turn you can reach 7-cost cards. This rapidly increases your mana, lets you dominate the board with high-cost cards, and closes out the game.

3. Strengths

  • Massive resource generation from Yobinion Malulu + Deddam, Disaster (6 mana as early as turn 3).
  • Many cards that trade one-for-two or better, such as Fumishuna, Sword Reaper and Perfect Darkness.
  • A wide variety of customization directions, making it easy to try out your favorite cards.

4. Weaknesses & Notes

  • The early game is fragile.
  • Weak to disruption of "Yobinion" (if a meta card like Primal Giant shuts down Yobinion Malulu, you can easily lose).
  • Without modification, it has few defensive measures.
  • However, once you survive the early game, the rest of the match becomes yours.

5. Card Guide

Faerie Life
001

Faerie Life ×4

×4 / Spell / Nature / Cost 2

Role: Mana acceleration

Basically cast it on turn 2 to connect into a 4-cost play on turn 3. If you have no 4-cost card in hand, cast it on turns 2 and 3 in a row to aim for 6 mana on turn 4. Has Shield Trigger.

Faerie Re:Life
002

Faerie Re:Life ×4

×4 / Spell / Nature / Cost 2

Role: Mana acceleration (with a defensive ability)

Has G-Strike (makes one opponent creature unable to attack). It can be shuffled back and buried as a shield, so when you have both this and Faerie Life, use this one first.

Wakumuterasu, Blue Wolf of Abundance / Original Life
003

Wakumuterasu, Blue Wolf of Abundance / Original Life ×2

×2 / Twinpact card (creature / spell) / Water/Nature (multicolored = tapped when placed in mana) / Cost Creature 4 / Spell 2

Role: Mana acceleration (also a draw source)

Basically use it as Original Life for mana acceleration. When you want to replenish your hand in the mid game or later, choose Wakumuterasu, Blue Wolf of Abundance, which draws 2 cards when it enters.

Deddam, Disaster
004

Deddam, Disaster ×4

×4 / Creature / Water/Darkness/Nature / Cost 3

Role: Core card that grows hand, mana, and graveyard at once

When it enters, sort the top 3 cards of your deck into hand, mana, and graveyard (one each). Use it to step up to 6–7 mana, and also to set up cards you want to revive with The=Killer Kinari, Doomsday Sutured King or Perfect Darkness into the graveyard.

Yobinion Malulu
005

Yobinion Malulu ×2

×2 / Creature / Nature / Cost 4

Role: The heart of the deck. Resource generation engine

"Yobinion" lets you cheat Deddam, Disaster into play when summoned. Then, when a second creature enters, put the top card of your deck into hand or mana. When in doubt, put it in mana to make later turns easier. A single summon secures 1 card in hand and 2 in mana, and is the starting point of the "2-4-7" curve.

Timpani = Simbarry
006

Timpani = Simbarry ×3

×3 / Creature / Darkness / Cost 4

Role: Removal slot with "Yobinion"

Blocker + "Yobinion". When a second creature enters, you can destroy itself to destroy one opponent creature. It does not choose the removal target, so its strength is being able to destroy creatures you normally can't choose, such as those with "Just Diver." You can also choose to keep it as a Blocker instead.

Yobinion Tribe
007

Yobinion Tribe ×2

×2 / Creature / Nature / Cost 4

Role: Deployment slot with "Yobinion"

It can be summoned from the mana zone, and since it returns to mana when destroyed, you can replay it with no loss. Using it from hand to cheat out Deddam, Disaster is also a strong play.

Fumishuna, Sword Reaper / "This path ahead is one of carnage."
008

Fumishuna, Sword Reaper / "This path ahead is one of carnage." ×2

×2 / Twinpact card (creature / spell) / Water/Darkness (multicolored = tapped when placed in mana) / Cost Creature 4 / Spell 5

Role: Hand destruction + draw, or a defensive trigger

The creature side does random hand destruction when it enters + "draw 1 card when the opponent discards." It chips the opponent away without reducing your own hand, and it is also a Blocker — a top-class card. The spell side "This path ahead is one of carnage." is a Shield Trigger that lets you choose "draw 1" / "return an opponent creature to hand" twice, and can serve as a mass removal in the late game. Neither side is ever dead — a versatile card.

Perfect Darkness
009

Perfect Darkness ×3

×3 / Spell / Darkness / Cost 5

Role: All-purpose removal — hand destruction / revival / power minus

Choose twice from "hand destruction" / "put a cost 4 or less Darkness creature/aura from your graveyard into play" / "give an opponent creature power -4000." It can also be cast from the graveyard, so after casting it from hand you can cast it again from the graveyard the next turn. When you can revive Fumishuna, Sword Reaper, reviving is often better than two hand destructions.

Gaiash Kaiser, the Meteor
010

Gaiash Kaiser, the Meteor ×3

×3 / Creature / Water/Nature / Cost 6

Role: Draw + high-cost reduction + counter

Draws 2 when it enters, reduces cost 10+ creatures by 4, and stops opponent attacks from Speed Attackers and the like. It also has a counter that lets you summon it for free at end of turn if the opponent cheats something into play. This deck has many reduction targets (6 cards), so it is strong even just played from hand. A bridge to your high-cost finishers.

Counterattack Skysword
011

Counterattack Skysword ×2

×2 / Creature / Nature / Cost 10

Role: Shield Trigger removal + deployment counter

When it enters, put one opponent creature into mana and cheat a creature out of your own mana zone. It becomes a strong counter when triggered. Candidates to put out are Blockers like Fumishuna, Sword Reaper and Olgate, Blade General of Demon's Birth, or Gaiash Kaiser, the Meteor if the opponent has many Speed Attackers. If your mana is built up, you can also chain into a second Counterattack Skysword.

Jigokubunker Par 459, Ninth Dragon
012

Jigokubunker Par 459, Ninth Dragon ×1

×1 / Creature / Nature / Cost 12

Role: Mana recovery + Mach Fighter

Sympathy makes it cheaper by the number of cards in your mana. When it enters, it increases mana while recovering a card from mana to hand. Return a finisher you buried in mana early on back to your hand to close out the game.

Olgate, Blade General of Demon's Birth
013

Olgate, Blade General of Demon's Birth ×2

×2 / Creature / Water / Cost 7

Role: An all-purpose game-maker that is easy to deploy

"Hyper Energy" lets you tap your own creatures of differing costs for a large reduction (e.g., tap 2 to summon for 3 cost). "Just Diver" lets it survive one turn, it is a Blocker, and when it enters it returns an opponent creature to hand. Furthermore, on the opponent's turn it can copy the come-into-play effect of an opponent's creature. It takes the initiative on both offense and defense.

CRYMAX Jaouga
014

CRYMAX Jaouga ×2

×2 / S-MAX Evolution creature / Darkness / Cost 7

Role: Finisher

It can be summoned without an evolution base and can attack the turn it enters. When it enters, set both players' shields to 3, Triple Breaker + when it attacks, destroy an opponent creature + 2 hand destruction. Since it also reduces your own shields as a drawback, play it on the turn you decide the game or the turn you make your board rock-solid.

Ragnarok, the Watch
015

Ragnarok, the Watch ×2

×2 / Creature / Water / Cost 10

Role: Lockdown-type finisher

When it enters / when it attacks, return 2 creatures to hand, and it can skip turns in response to opponent actions (creature entering / spell). It is heavy, so basically reduce it with Gaiash Kaiser, the Meteor to play it. Note that it cannot stop the attacks of creatures already lined up.

The=Killer Kinari, Doomsday Sutured King
016

The=Killer Kinari, Doomsday Sutured King ×2

×2 / Creature / Water/Darkness/Nature / Cost 10

Role: Lockdown-type finisher (with removal resistance)

When it enters, return opponent creatures to hand while reviving from the graveyard, and nullify the come-into-play effects of opponent creatures. EX Life keeps it from being easily removed. Use it versus Ragnarok, the Watch based on whether you want to stop summons/spells or erase effects.

6. Basic Play Flow

Early game

First, mana acceleration. Build mana with Faerie Life and Faerie Re:Life, and use "Yobinion" cards to put out Deddam, Disaster. If you can involve Yobinion Malulu, your mana and hand come together at once. Aim for 5–6 mana.

Mid game

Widen the resource gap with draw and hand destruction. Aggressively use cards that trade one-for-many, like Fumishuna, Sword Reaper and Perfect Darkness, to build an advantage. If you have room, add another Deddam, Disaster or use Gaiash Kaiser, the Meteor to bridge to high-cost finishers.

Late game

Once creatures are lined up and mana is built, summon a finisher. Any of them can swing the game state hugely, so push through with overwhelming power.

Tip for improvement: When you dig through your deck with "Yobinion," you may reach the same spot again in the late game. Remembering "how many cards were revealed" and "whether finishers like Ragnarok, the Watch or The=Killer Kinari, Doomsday Sutured King were revealed" makes it easier to plan your late-game line.

7. Final Summary

A big-mana control deck that ramps from "2-4-7" into powerful cards. The resource generation of Yobinion Malulu and Deddam, Disaster is the core, you create a trade gap with Fumishuna, Sword Reaper and Perfect Darkness, and you push through with heavyweight finishers. Its weaknesses are early-game fragility and "Yobinion" meta cards.
