Kaiki the Unity Star →Used Deck

It can't be weak with self-regeneration ability with built-in fusion. It overcomes the roughness of consumption of fusion brilliantly.
It is very reassuring to be able to use this card to fuse many times without the disadvantage of banning after regeneration, which is common in self-regeneration systems. The cost of 500LP is as good as nothing.
The key is how to satisfy the self-regeneration trigger, but that is also where the duelist's skills can be shown and the fun of building.
Konami's assumption is that it will be combined with the Kachidoki-kun card 《Hayate the Earth Star》, etc., but depending on the construction even if there are no other Kachidoki-kun cards, this card pin stabbing will also work.
There are also many small Good points.
The first is that fusion after self-regeneration is optional. It can also simply self-regenerate into a wall. The range of playing is expanded, such as making it the cost of other cards.
The second point is that he has 2100 DEF, so it can be a minimum wall.
Third, he was born a LIGHT level 5 Warrior. 《Feast of the Wild LV5》is compatible with 《Constellar Pleiades》.
The fourth point is that you don't have to use this card as a material when fusing. Normally, you would use this card as a material to get 《Idaten the Conqueror Star》, but as long as you have the materials for Warrior Fusion Monster, you can get anything out of it.
The fifth is that the timing of resuscitation is Friche. If you are worried about maintaining the Warrior on the field, which is the trigger, such as when the opponent's Kaiju is in the hand, you can fuse in the opponent's draw phase or standby phase first and issue 《Idaten the Conqueror Star》etc. and just search. However, you can also take actions to avoid risks such as using it, and you can respond flexibly.
Kachidoki-kun is apt to be teased for his lines, but since the card that came out can't be given a common name, he didn't categorize it and became a general-purpose Warrior support character. .

With the effect of (1), I think that it is excellent that if you Special Summon with the effect of "Hayate the Earth Star", you can connect to "Idaten the Conqueror Star".
After that, use the (1) effect of Idaten the Conqueror Star to search for a second Kaiki the Unity Star, and send the Kaiki the Unity Star searched for by the (2) effect of Idaten the Conqueror Star to GY as a cost, during the next opponent's turn. I think it's also attractive to be able to connect Kaiki the Unity Star's (2) self-regeneration effect to Shura the Combat Star.

what! ? Doesn't Fusion Summoning require his Spell Card of Fusion!? ?
If Special Summoned, pay LP, Warrior's Fusion Monster can be his Special Summoned effect, and when there is an advanced or higher warrior with his ATK different from his original ATK on the opponent's turn. It has a revitalizing effect.
Even if you don't rely on his fusion spell card, you can access Idaten just by special summoning this card with Hayate, so it's a must-have card in the Kachidoki Deck. Even after the Idaten fusion, if Idaten's effect raises her abilities, she can aim to fusion summon Shura.
Kachidoki If you are aiming for fusion in the deck, this card will be indispensable after this.

Fusion built-in monster
There is no exclusion demerit, so if the conditions are met, you can fuse every turn.
