How to use this deck

Hammer Shark

  • Your key card in this deck is Hammer Shark. Summon it as soon as possible to gain immediate control of the field. It's a 1900 beater along with the field spell card Umi, it gives access to your other monsters to be special summoned in the field.
  • Uminotaurus on the other hand is a great addition to this deck. Another 1900 beater along with the field spell card Umi. All of your monsters will benefit from its effect since the Monster Types in this deck is composed of Fish, Sea Serpent and Aqua-Type. It lets those types of monsters to deal damage even if your opponent's monster is in defense position.

Great addition

  • You can summon a Hammer Shark and activate its ability to special summon Beautunaful, this can then be banished to search for other low level fish type monsters, and in a Hammer Shark deck, you will have plenty of options to summon. Alternatively, you can banish Beautunaful to summon another Hammer Shark and activate the second Hammer Shark's ability to special summon another monster from your hand, giving you 3 monsters in a turn.
  • Since Hammer Shark can special summon another monster, you can use the other monster to be tributed so it will not leave you defenseless, and will give you an extra draw as well.


  • Play defensive with Yomi Ship and Needle Sunfish by setting them, let your opponent's monster attack.

  • You can also pressure your opponent by putting Yomi Ship in face up attack position and crash it with their monster. This might force them to use their back row if they do not want their monster to be destroyed.

  • If your opponent has two monsters on the field, activate the second effect of Enemy Controller to your Needle Sunfish. Take control of your opponent's monster with lower attack and use Needle Sunfish effect on the other one.

Boost and removal

  • Activate Hammer Shark's effect if possible, summon/special summon Lost Blue Breaker and use its effect to destroy your opponent's back row. Once you cleared your opponent's back row, your attacks now can not be interrupted, unless they have a Sphere Kuriboh on hand.

  • Even if your field spell Umi is destroyed, it can be compensated with the effect of Star Boy. Get over the attack of your opponent's monsters by summoning/special summoning Star Boy to buff up the attack of all your monsters. Hammer Shark's attack can go up to 2,400 with Star Boy and Umi on your side of the field.

Activate this card if you do not have a Hammer Shark, or if there are other cards that you need. Just make sure that you have enough monsters to defend your field, since you will be shuffling back two water monsters from your hand to your deck.
Sea Lord's Amulet

Activate this card to prevent your monsters on the field from getting destroyed by card effects for three turns. This card also serves as distraction for your field spell card to be destroyed since your opponent might be forced to target this card instead of Umi.

Decks as naturia and rebd, are quicker to summon than hammer shark, but making some adaptation you can make it with a deck similar, is about which cards you have to counter a rebd

Yomi, lost blue, metalmorph and 2 econs instead of kuribo, fish charge, riryoku, orb and windstorm. I climbed from silver 1 to plat 5 with this deck in almost 2 days with a win rate of about 90%

Super Rush Headlong is a much more powerful defense option instead of Metalmorph, Kuriboh and Security Orb. Change Riryoku for a defensive card.

Add Daedalus, delete one star boy, his effect will destroy everything in both sides and can attack directly

this deck does not need daedalus. hard to summon and blowing up the board doesnt really do anything in a deck where you constantly pressure your opponent anyways

This deck is so weak to possessed dark soul it's crazy. I just destiny draw him and steal a full set of 17-1900 monsters.

But since Relinquished is kinda dead, nobody runs Possessed Dark Soul anymore :(

Is a second mirror wall recommendable for this deck? If so, I'll have to start gem-digging the Neo Impact pack and I'm worried they may limit this card...thanks in advance

It would be nice to have but you definitely don't need a 2nd one. If you have trouble getting over big monsters you can try using Metalmorphs or more Yomi Ships

I'll stick to the other good old traps then. Thanks a lot!

Way too damn good. Why did Konami feel the need to buff Mako further? He was already great after hammer shark.
Anoymous 25days ago
a legendary ocean might be a good pick here if it decreases the level of hammerhead shark by 1, you can summon another shark with it's effect

Absolutely! This allows Level 4 monsters to be summoned by hammerhead. Hammerhead summoning an amphibian bug for direct damage... wow

No, Legendary Ocean wastes deck space and is a dead draw most of the time. Hammer Shark decks don't care about a monster that is able to attack directly, either, since the main point of the deck is to gain board advantage quickly. Bugroth is still a bad card, and so is Legendary Ocean.

I disagree. legendary ocean is a good addition to this deck because of the interaction between it and hammershark also it is a second umi for levia dragon
<< Anonymous(Little kuriboh)

Legendary Ocean wastes slots and is a dead card unless you have Shark + Ocean + Level 4 in your hand. Daedalus is bad as well. Better off just running 3x Shark, 3x Yomi, a mixture of 1-3 of Lost Blue, Needle Fish, and Star Boy. Rest of the deck is just various support cards like Mirror Wall, Metalmorph, Econ, etc
