The most important card in Crystron.
Due to the nature of the effect, he can send his Crystron in his hand to his GY and increase his deployment power, so Scrap recyclers will drop it into his GY first.
Without it, Crystron would still be a weak deck even with Halifibre.

Machine ... 5 stars ... Easily Special Summon ... Ah! (Guess)
Also known as Crystron/Fortress, it's a card that can be used as a cost for Crystron as long as it doesn't have the same name.
It's not an exaggeration to say that it's a god card, as it's able to compress the deck and self-destruct it, so it's easy to think about combos.
However, cards that are overloaded or avoid hand accidents may cause accidents, so be careful about the number of cards.
Isn't it strange that such a good and essential card is so rare?
At that time, I thought it wouldn't be strange if it was recorded as a super rare song.
It's a machine, so it's also a point that it's easy to drop with a scrap recycler.

Crystron makes all the difference how fast he can send this to GY

You can do a Special Summon using your hand and field as a cost, but since it's a 1:2 exchange, you don't have to pay too much attention to it.
Even if you are destroyed, you can immediately get a replacement, so depending on the monster that comes out with a 1:1 here, you can also benefit!

His level 5 Crystron that can be revived by discarding his Crystrons other than those with the same name in his hand, or from his hand. It's even better if you connect it to his GY effect of his Crystron as a cost.
After that, if you destroy yourself with the effect that destroys your own card, you can connect to Recruit, and it is possible to compress the Deck and expand it widely.

A monster that can be easily put out by cutting his Crystron in his hand. Even in GY, it is great that you can do Special Summon.
After that, there is an effect that destroys your own card, but you can also select yourself and you can also recruit as it is.
In Crystron, where the Tuner level is generally low, it is a monster that is useful for high-level synchros.

With the effect of (1), you can make yourself her Special Summon and self-destruct, and with the effect of (2), you can recruit your favorite "Crystron" monsters.
Many of the "Crystron" cards can be activated by her GY, so I think the cards sent to her GY by the effect of (1) will not be wasted.
(1) Her Special Summon effect works not only from her hand but also from her GY, so I think you should send it to GY in advance with Scrap Recycler etc.

The specs of a Level 5 Machine are reminiscent of Nova Infinity. If you combine it with 《Quickdraw Synchron》, you can also get Tsiolkin, but in this Synchro Summoning Abomination Deck, extras are hard to come by.
If you discard his Crystron other than your own, you can effectively search for his Crystron from the deck, so you can effectively use his Crystron that is rotten in your hand.
It's a pretty strong effect, but it only works once per turn, so be careful not to overload it.

Advanced cards would be appreciated by his Crystron.
As a non-tuner, he seems like an important card for Crystron.

In the main deck, it's the only high-level Crystron, and in Crystron, where low-level cards tend to be duplicated in the hand, it's a card that kills two birds with one stone, as it allows you to discard low-level cards that you want to use his GY effect while deploying.
You can discard 1 Crystron and do a Special Summon on your own. After that, you have to split 1, but you can split it yourself. Yes, it can be recruited with the same name, so you can practically use it like a Crystron exclusive trick, but if you can destroy something like Different Dimension Deepsea Trench, it's even tastier.
It can be revived even from GY, and there is no advantage of being banished, so it's nice to be able to use it every turn as long as you have a hand.
And ★5 Machine... No, it's nothing.

Are you there?
His Crystron's first advanced with self Special Summon effect and recruit effect when destroyed.
When Special Summoned, it requires destruction as a cost, but since this cost includes itself, destroying itself will play an active role as an all-purpose recruit for low-ranking Crystrons.
Basically, if you search for tuners, it will be easier to connect to Synchro Summons, and if you search for non-tuners, it will be a stepping stone to connect there.
It is quite powerful that it can be activated even from GY. Even if you stack too many cards, there is a limit on activation, so there is no point, but it is a card that you want as soon as possible.

A long-awaited key card for the Crystron Deck that allows you to deploy low-level Crystrons without sacrificing summoning rights.
Or rather, I can't help thinking that the Crystron theme was designed with this card in mind.

It is basically used as a low grade replacement. However, it can avoid the accident that all the cards in the hand are low-level tuners, and the non-tuner is not an effect that will cause such an accident in the first place. If anything, I would like to find value in the fact that you can continue to develop even if you lose the right to summon. GY has Smoger, but when his hand doesn't have his low class Crystron card and the deployment is cut off, it's also a strength to be able to discard the trap and replace it with a low class. However, since the same name cannot be used as a cost, be careful not to overload it.
