Kairyu-Shin's Dark Reef →Used Deck

An expansion trap card that allows you to special summon 1 to 5 monsters in a specific range from your hand or deck using the sea in your field as a cost, and the maximum limit is 2 without additional effects.
You can recruit multiple sea-related monsters, and depending on the summoned monsters and the timing, you can use them to attack or interfere, but since the sea is consumed when activated, the disadvantage when negate is simply numerical. Even if you go through it, the sea, which is the source of the power of the recruited monsters, has been lost, so it is essential to use it in combination with Sea Stealth or immediately recover it with the remake Ocean Dragon Lord or Miko. .
If you aim for maximum deployment, you will have to put multiple Normal Monsters in the deck, which will increase the accident rate considerably, so the additional effect is an attractive return, but shouldn't you build it so that you can use it forcibly? .

A trap card that can recruit up to 5 WATER monsters using the sea as a cost.
If you Special Summon a monster with 《Mega Fortress Whale》on your opponent's turn, you'll be able to shave off his LP all at once on the next turn with a direct attack from that effect. Special Summon in Defense Position doesn't matter as long as it can be used in the opponent's end phase.
However, the fact that the sea is used as a cost is quite heavy, and cards that require the existence of the sea as a condition cannot be applied, and it is necessary to secure another sea for the next turn's direct attack. If you have 《Dive Sea Surprise II》, you can combine it with the Sea of Field Spell, which makes it a good matchup.
Also, in order to Special Summon WATER Normal Monsters, it is necessary to use them in the deck, which increases the accident rate.
It is a strong card that can decide the game by attacking all at once, but it can be said that it is a high-risk, high-return card because it requires a lot of cards and has the slowness of a Trap card.

Trap with high deployment power.
However, as a deployment card, he feels slow because he is a trap, and he can draw sea-related cards, but he costs sea, so there is a risk that he will not be able to exert much influence or weaken the board. .
If you have a submarine surprise attack, you can immediately reactivate it, and if it's II, it's a Continuous Spell, so you can keep two copies together with Field Spell, so I definitely want to use it together. Impression that it is for superiority rather than turning back.
It has some quirks, but I think it's a card with a reasonable return.

Can be searched with 《Ocean Dragon Lord - Kairyu-Shin》, play 《Maiden of the Aqua》and 《Electric Jellyfish》or 《Mega Fortress Whale》to protect the Ocean Dragon Lord, or activate when the Ocean Dragon Lord or the sea is eliminated, and the second Ocean Dragon Lord and a shrine maiden to maintain the effect of restricting the deployment of the Ocean Dragon Lord. In addition, 3 water vanillas can be deployed, and if you call 3 Frostosaurus, the total RBI is 7800. WATER Even though it's bound, there's a decent degree of freedom in deployment thanks to the white toki and shark.
However, Physalia can be discarded, and although Water Vanilla is somewhat similar to 《Fish Sonar》, it is difficult to require a large number of undrawn cards for operation. If used in combination with 《Dive Sea Surprise II》, which can be treated as the sea separately from the Field Spell, or 《Sea Stealth Attack》, which can reactivate the sea that went to GY at a cost, the sea can be maintained even after activating this card without spending Maiden of the Aqua. I can afford both Physalia and Mega Fortress Whale. In addition to 《A Legendary Ocean》and Ocean Dragon Lord, the number of required cards is increased, and the power of the submarine surprise attack is not high, but it is not a good idea to aim for such an upside. However, I would like to include one for Maiden of the Aqua.
There are 《Fury of Kairyu-Shin》and 《Rage of Kairyu-Shin》cards that can be searched from Ocean Dragon Lord and can be used without drawing loss cards. Since is the top, is it a card that should be used even if it is a draw loss card?

That said, I'd still like to include one for Maiden of the Aqua.
