Stealth Kragen Spawn →Used Deck

With the effect of 《Number 4: Stealth Kragen》, you can deploy up to 2 monsters, and by lining up with 《Number 4: Stealth Kragen》, you can remove monsters in a free chain 3 times, which I think is excellent.
If it's a "Shark" deck, he's good at deploying WATER monsters, so I think it's a good match.
I think the strength of this card itself is that it can revive 《Number 4: Stealth Kragen》with X materials.

It has the same effect as No.4, but it has no attribute change effect or burn, so it can be said that it is a subordinate effect.
However, it can be expanded by the effect of No.4, and it also supports the aforementioned effect, so it can be said that it is a card for No.4.
When destroyed, he can revive Stealth Kragen, mostly reviving No4. He himself is often deployed from No. 4, but there are many cases where he cannot be revived because he cannot meet the resurrection restrictions because he is non-regular.
More to say, No4 is excellent enough just for attribute change and removal, so it would be difficult to say whether this card is essential, so my impression is relatively weak.
However, since it is an auxiliary existence that restrains No4's destruction, respect should be paid.

Simplified version of Stealth Kragen. Unlike Numbers, monsters in the field cannot be used as his WATER, so it's a little difficult to use, but Numbers' Stealth and Kragen effects can easily bring them into play.
It is strong against destruction because it can bring out "Stealth Kragen" other than itself when it is destroyed. In the original, only Ephyra and Numbers appeared, but if new ones like "Planula", "Polyp", "Strobila", and "Metaphyra" come out, I think this effect will shine even more.

To put it simply, No. Clagen whose removal effect has weakened as much as it has been split and revived.
Basically, it's a bonus monster summoned by No. Kuragen's effect, but if you want to respect Kurage-senpai, use it.
It puts pressure on the frame of the Extra Deck, but if you use the resurrection effect in the latter half, you can make a powerful No. Kuragen 《Back to the Front》, which increases the stability of the Jellyfish Deck.
In addition, it has its own merits, and since it is not a No. monster, it can be used as a material for 《FNO.0 Future Emperor Hope》. If you're lucky enough to have two left, you can pop them out with just that, so it's fun to aim for them.

In terms of setting, it is a very rare X-Monster that is a descendant of Numbers, which is said to be the only one in the world. Since there is no transformation effect, the suppression power and usability of the Friche explosion effect is greatly reduced, and the effect damage is also gone.
Also, if he is Special Summoned by the effect of Numbers X, including the effect of the main body, he will revive Stealth Kragen up to the number of X materials he had when he fell, and share GY's WATER monster as X material. I can.
Currently, there are only two types of Stealth Kragen monsters, the main body and Ephyra, but since the Ephyra summoned from the main body does not meet the resurrection restrictions, it cannot be revived by this effect, and the Ephyra must be summoned from the EX Deck by the main body's effect. Since you can't use the effect when you fall down, there is little advantage to X summoning this first, and basically you will be reviving the main body that summoned Ephyra.
In such a situation, I can't make a good ring, but I'd like to do something about it with Seanettle's help.
Numbers Kragen alone is strong enough to be the main body, so it's very difficult to ask if it's really necessary to adopt this card, but if the Deck uses something like Torrent Funeral, it's a special monster. So I personally think it's a monster that I want to adopt after all.
Since the effect doesn't have the name Turn 1, it would be ideal if you could line up the main body and two Ephyra at the same time, but it might be easier and stronger to line up two main bodies.
