  • 35,000 Gold
  • SR Jewel x4
  • Stone of Water x40




  • 1900 attack with Umi, which can be activated easily using Mako's skill "Mystic Depths"
  • Can special summon level 3 or lower water monsters from your hand.


  • Can only special summon monsters from your hand.
  • Lowering its level can make it vulnerable to Possessed Dark Soul.
  • Summoning multiple monsters from your hand quickly can result in a card disadvantage. This will make it more difficult to comeback if your opponent can counter them due to lack of cards that can help with more draws.
  • Will not be able to special summon when its level is at 1. Using A Legendary Ocean will reduce its level, making it usable 2 times only, instead of 3.

Tips, related cards, skills

Cost Down

Can be used to reduce the level of the monster cards in your hand

Water Hazard

This lets you special summon Hammer Shark without using up your normal summon for the turn, allowing you to summon 3 monsters in a turn, but can only be activated when you have no monster on the field.

Hydro Pressure Cannon

Will be equippable to Hammer Shark if it's able to activate the ability at least once.

Beautunaful Princess

A useful search card to special summon a monster from your deck to find one that you need, or special summon another Hammer Shark from your deck, and use its effect to special summon another monster from your hand.

Fish Depth Charge

Can be used to destroy any card on the field, and draw a card. Good with Hammer Shark since you can use this on your second monster, so that it won't leave you defenseless.

A Legendary Ocean

This will lower the level 4 monsters so you can special summon them with Hammer Shark's effect, but will also lower the number of times Hammer Shark can use its ability.

Give and Take

Increasing Hammer Shark's level will increase the number of times Hammer Shark can use its effect, but you will have to send your monster from the graveyard to your opponent. You can give your low defense monster to your opponent, and use Uminotaurus to deal piercing damage to it.

It is a great card for water decks.

Furthermore, When the game advances to the Zexal era of Yugioh it might be a staple card in the character deck known as Reginald Kastle.

Reginald Kastle surnames were called Shark & Later on Nash.

Reginald Kastle is a main friend/rival to the star of the shown Yuma. Similarly, I believe Reginald's role was akin to Kiaba role vs Yugi.

He was one of the greatest threats & greatest friends with the same pompous attitude which made that season very reminiscent to the Original Yugioh series.

Through the course of the Zexal Series Reginald Kastle deck evolved.

Reginald Kastle had 4 different main boss monsters through out the course of the series.

Original Boss in the beginning was:
Black Ray Lancer + Armor evolve form AKA Full Armor Black Ray Lancer

The above deck is really were Hammer Shark shined. Black Ray Lancer was a Rank 3 XYZ which needed Hammers effect to lower himself to level 3 + summon another level 3 for the XYZ summon.

Sadly, Hammer Shark fell a little out of favor in later parts of the series mainly due to the new boss monsters which Reginald acquired.

Yeah, I'll save Hammer Shark for later.

In case people want to know the bosses were:

1 - Black Ray Lancer
2 - Shark Drake
3 - Abyss Splash
4 - Silent Honor Ark

Out of his 4 different bosses monster.
I have to admit Shark Drake was my favorite one.

It was probably the most dominate boss monster for the majority of the series.

It was also the hardest to summon which always made duels awesome to watch!

3 level 4 monsters to summon? lo

Haha, I know what you're saying! Hammer Shark + Needle Sunfish = Black Ray Lancer would be brutal. A good XYZ with the bonus of lowering -500 ATK, thanks to the effect of Sunfish? Count me in!

Shark Drake was my favorite too. Dominating, strong AND badass.

Having same problem
Bought one but haven't seen any more in card trader for weeks??
Add Magical Reflect Slime to the list of 3 or lower water monsters that can be summoned by this card. Might actually give you a chance to use it's effect against an opponent.
