With the addition of new cards such as Beautunaful and Fish Depth Charge, Mako Tsunami becomes more viable again. This might help Players who is a fan of FISH type decks to increase the competitiveness of their decks.
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.
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.
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.

OK, gotta say something bout hammer shark deck,I think it is extremely underrated, played the reseted season got to plat5 with red eyes zombie but couldn't rank up from there, dropped back to plat3, switched back to hammer shark and got to straight to legend 1
HammerShark beating Naturia heavily depends on the situation. Naturia is more susceptible to bad hands, but swarms way better than HammerShark. Naturia's swarm monsters are also alot stronger than HammerShark's. HammerShark can boost water monsters with StarBoy, but StarBoy can only last a few turns max since pretty much all Naturia monsters can defeat StarBoy.
Lastly, Exterio's Fang can actually counter activation, while BlueBreaker can only destroy. Overall HammerShark would be better in a general case, but Naturia is so powerful in a single niche with slightly better backrow counter it usually overpowers HammerShark.
What general are you talking about? Naturia have good matchup again Warm Worm, Weevil, Phoenix with pretty much destroy Hammer Shark. In all honest, everysingle tier 1 deck currently destroy hammer shark, what general? Vanilla beatdown?
