18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

Water monsters have a lot of different types, which makes it hard and confusing to make a water deck without using templates.

A lot of water support cards have abilities that use aqua, sea-serpent, and fish types. The aqua type is especially interesting.

Aqua monsters don’t usually have as much force as other water monsters, but their effects make up for it.

This list looks at the best water-type monsters in the game. These monsters work well in many different decks, not just water-based ones.

What Is the Yu-Gi-Oh Water Attribute?

Many Yu-Gi-Oh cards help a certain type of structure, but the water trait has a few general supports that work well with a wide range of structures.

Water supports come in many different shapes and sizes. They can boost the ATK of your monsters, make them easier to call, or make them immune to being destroyed in battle.

Most water monsters have the type aqua, fish, or sea snake, but many cards go against this trend, giving the game even more variety.

But there are so many water supports to choose from, which ones are worth your time? Here are the best water-themed cards. Yu-Gi-Oh deck!

18. Aquarium Set

Best Aqua Monsters

Continuous spell Aquarium Set is good for any water-themed build and kills Aquaactress monsters. First, all water monsters you control get a 300 boost to both their attack and defense.

Your Aquaactress units also get a 300 ATK/DEF boost, and since they are made of water, they get a 600 total boost.

But even if you’re not using that archetype, when Set is sent from the field to the graveyard, you can bring back an aqua-type monster from your graveyard.

However, you can’t special summon non-aqua monsters for the rest of the turn.

Aqua is by far the most common water type, so you can easily use this great revival unless you’re playing a rare fish or sea serpent-only build.

17. Graydle Dragon

MTc0NDYwODc0OTczOTgwMjk0 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

Graydle Dragon is a powerful support and fighter, but its name doesn’t give away that it’s an aqua type. In fact, you need an aqua tuner (but any type of non-tuners) as material, but you can use any other type of non-tuners.

Graydle has a scary 3000 ATK, and when you synchro summon it, you can target and destroy up to the number of water materials used in Graydle’s casting to destroy cards your opponent controls.

This should be at least two and maybe even more in water decks, making it easy to get rid of any type of enemy card.

Also, if Graydle is killed in battle or by an effect and sent to the graveyard, you can special summon a different water monster from your graveyard and cancel its effects.

Even if the ability is disabled, this can bring back powerful battle cards or just give you something to use in a tribute, synchro, or xyz summon. Or link. Or mix. Or ritual. You get the idea.

16. A Legendary Ocean

MTc0NDYwODc0OTczOTE0NzU4 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

This classic field spell gives all water monsters a 200-point boost to their ATK, giving them a strong edge in battle. Its name is treated as “Umi,” which helps cause effects that depend on Umi.

Not only that, but Ocean lowers the level of all water monsters by one, so you can normal summon level 5 monsters without making a sacrifice or level 7 monsters with only one sacrifice (instead of two)!

Keep in mind that these boosts help both players, so you could help your opponent, but Ocean has access to some very strong cards.

You can now easily call the level 5 “Giga Gagagigo,” whose base 2450 ATK is higher than that of even the “tribute” Monarchs. The “Warrior of Atlantis” monster or the “Terraforming” spell can also quickly search the Ocean.

Lastly, “Lemuria, the Forgotten City” is a good water field to use if you want to raise the levels of water monsters instead of lowering them (maybe for better XYZ summons).

15. T.AD.P.O.L.E

15 t ad p o l e card yugioh 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

With 0 ATK and 0 DEF, it would be easy to think that putting this card on the list was a bad joke.

The only thing T.A.D.P.O.L.E. does is let you add other T.A.D.P.O.L.E. cards from your deck to your hand when it is killed in battle.

But if you have a lot of these things in your Graveyard, this card works well with Des Frog (a little further up the list), which can clear the field and even kill you.

This little monster has a lot more going on than meets the eye.

14. King Of The Swamp

14 king of the swamp ygo card 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

If you play a Fusion deck, it turns out that a monster with the Aqua type is one of the best cards to help you do a Fusion Summon.

King of the Swamp works well in a Water Fusion deck, but it works just as well in any other deck.

With only 500 ATK and 1000 DEF, this monster is best used for its affect, which lets it be used in place of any fusion material.

This can be very important if your opponent gets rid of a monster you needed.

If you have all the parts for a monster and just need Polymerization to put it all together, you can even send King of the Swap to the Graveyard to draw that much-needed fusion spell from your deck.

13. Testudo Erat Numen

13 testudo erat numen card 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

A lot of the Aqua monsters in this list are kind of weak when it comes to ATK/DEF.

Luckily, there are ways to make these numbers not mean much.

And this next card is a good example of that.

Testudo Erat Numen is a level 1 monster with 0 ATK and 1800 DEF.

But as long as it’s on the field, neither player can Special Summon a monster with more than 1800ATK.

For many decks, that can be the only target for their Special Summons.

And if you combine it with the Barrier Statue of the Torrent, your opponent won’t be able to call anything at all.

12. Barrier Statue Of The Torrent

12 barrier statue of the torrent ygo card 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

I really tried to think of a funny joke about torrents and floods, but, uh, yeah.

This card is better than that joke, no matter how funny it would have been.

Barrier Statue Of The Torrent is LVL4, but it only has 1000 ATK and 1000 DEF.

But if your opponent doesn’t use a Water deck, it can make it impossible for them to use any of their tactics.

This card stops any Special Summons that aren’t Water monsters.

And if you put this on the field early, it can stop your opponent from even getting started.

11. Gameciel, The Sea Turtle Kaiju

11 gameciel the sea turtle kaiju card 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

Few things in Yu-Gi-Oh! are as enjoyable as seeing your opponent Summon their boss monster with joy, knowing that you’ll get rid of it on your next turn no matter what it is.

First, it’s important to know that you can send Gameciel, The Sea Turtle Kaiju to your opponent’s side of the field by sacrificing any of their monsters.

Giving a gift is neither a result nor a way to lose something.

So this takes care of almost every monster in the game that you can’t hit.

Giving your opponent a monster with 2200 ATK and 3000 DEF isn’t a big deal here, since it can be taken away by any effect.

10. Des Frog

10 des frog card yugioh 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

At first, this monster might not look like it has much use.

But with the right deck, it can let you cast one of the game’s most crazy-powerful cards.

Des Frog is a level 5 monster with 1900 ATK and 0 DEF. And since it can only be called by paying a gift, it’s hard to sell with stats like those.

But if you Tribute Summon this card, you can Special Summon as many Des Frog’s as you have T.A.D.P.O.L.E in your Graveyard.

If you get 3 cards on the field, you can use a Spell card called “Des Croaking,” which destroys every card your opponent holds.

This can OTK if you can find an extra 2300 ATK.

9. Danger! Nessie!

09 danger nessie ygo card 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

Danger! Monsters are great because they usually let you put another monster on the field for free.

The Aqua Danger, too! Monster isn’t the only one.

Danger! Nessie! Is a level 7 water monster that has 1600 ATK and 2800 DEF. You can show this monster from your hand and let your opponent choose a card at random from their hand to throw away.

If they don’t catch Danger! Nessie! , you can special summon it and then draw a card.

A cheap LVL7 with a high DEF isn’t something to laugh at.

At the very least, you can use it to make monsters that are bigger and stronger.

8. Leviair The Sea Dragon

08 leviair the sea dragon card 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

Having your cards in play makes them much more useful, regardless of whether you did the banning or not.

Leviair, the Sea Dragon, is an LVL 3 XYZ with 1800 ATK and 1600 DEF.

And this monster has a special effect: if you remove a material from it, you can Special Summon a banished monster with a level of 4 or less that you choose.

Some strong effects cost mana to discard cards, which is more permanent than just putting them in the Graveyard.

In a lot of decks, it’s helpful to have a way to get those cards back.

7. Mistar Boy

07 mistar boy yugioh card 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

There are a lot of ways that Aqua monsters can bring other monsters onto the scene.

So it makes sense that they have a strong Link Monster to use that.

Mistar Boy is a common card in many competitive decks. He has 1400 ATK and is a Link-2.

While this monster is on the field, all Water monsters get 500ATK/DEF and all Fire monsters lose 400ATK/DEF.

This can be very powerful in a Water deck.

You can add a Water monster from your Graveyard to your hand when this card is killed.

And this kind of Graveyard recursion is also very important in a lot of schemes.

6. Flip Flop Frog

06 flip flop frog card yugioh 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

A lot of Yu-Gi-Oh! monsters go after cards on the field and destroy them.

And that’s great, until you run into monsters that don’t respond to these effects.

Flip Flop Frog is a Level 2 card with 500 Attack and 200 Defense. But it has an effect that lets you flip it face down once per turn as a protection.

When it’s face-up, you can’return’ monsters to your opponent’s hand up to the number of face-up Frogs you control.

Since this doesn’t target or destroy anything, it can be used on almost anything, which could give you the freedom to attack your opponent directly.

5. Paleozoic Opabinia

05 paleozoic opabinia ygo card 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

You can’t talk about Aqua monsters without talking about the Paleozoics.

These cards are all Traps that can be used as monsters. Most of them are resistant to monster effects, which makes them very powerful.

Paleozoic Opabinia is an LVL2 XYZ with 0 ATK and 2400 DEF.

It can’t be hurt by monster effects, so it’s hard for your opponent to break through.

If this monster’s XYZ material is a Paleozoic Trap card, which it usually is, you can remove one of those materials to add a Paleozoic Trap from your Deck to your hand.

Even though the impact isn’t the best, this is a strong search card.

4. Paleozoic Anomalocaris

04 paleozoic anomalocaris card yugioh 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

Paleozoic Opabinia is also very good because it protects you and lets you get to your Trap cards.

But this is the card to play when you’re ready to go on the attack.

Paleozoic Anomalocaris is an LVL2 XYZ monster with 2400 ATK and 0 DEF. It is immune to monster abilities.

And if a trap is sent from your Spell/Trap Zone to the Graveyard, you can take the top card from your deck and add it to your hand if it’s a trap.

This is great, because they are used a lot in Paleozoic decks.

Also, if this monster’s element is a Trap card, you can remove it to destroy a card on the field.

3. Glacial Beast Iceberg Narwhal

03 glacial beast iceberg narwhal card 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

Even though many Aqua monsters are weak, that doesn’t mean they are all weak.

If you want a beat-stick that can cancel effects and cause burn damage, this monster fits the bill.

Glacial Beast Iceberg Narwhal is an LVL7 Synchro with 2700 ATK and 1600 DEF.

In addition to having good stats, this monster has a quick effect that lets it cancel an effect and destroy a card during the battle phase once per turn, as long as you control another monster.

If your opponent attacks your other monsters, they’ll have to be careful, because they’ll take 600 burn damage for each one they kill.

This monster is very useful because it gives your opponent a choice between two bad options.

2. Ronintoadin

02 ronintoadin card yugioh 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

Frogs and many other water monsters are good at swarming the field.

Ronintoadin might be the best at it, though.

Ronintoadin is a Level 2 monster with 100 ATK and 2000 DEF. When it’s on the field, its name changes to “Des Frog,” which can help with the Des Croaking Spell we talked about earlier.

But even if you don’t use it for its name, Ronintoadin has a strong Graveyard effect that lets you send a Frog monster to the Graveyard to Special Summon Ronintoadin back to the field.

This card can’t be used for Synchro, but it can be used for XYZ and Link.

Once you play this card, it will give you value for the rest of the fight.

1. Toadally Awesome

01 toadally awesome yugioh card 1 18 Best Aqua Monsters For A Water Deck in Yu-Gi-Oh!

Even if this monster was bad, its name alone should put it at the top of this list.

Still, it’s not a bad Aqua monster by any stretch of the imagination.

Toadally Awesome has been played in tournaments for more than four years.

This monster is LVL 2 and has 2200 ATK and 0 DEF. And its function is really what makes it stand out: during your Standby Phase, you can remove a material to Special Summon any Frog monster from your deck.

That’s already pretty good.

But this monster also has a quick effect that you can use once per turn: if your opponent uses a Spell/Trap or monster effect, you can send an Aqua monster from your hand or field to the graveyard to stop the effect, destroy the card, and then put it on your field.

Toadally Awesome has great benefits and is ridiculously easy to summon. When it is sent to the graveyard, a Water monster from your graveyard is added to your hand.

Huh, I guess this monster is ‘Toadally’ awesome after all!
