Mathmech Sigma →Used Deck

A card sent to his GY mainly as a cost of Mathmech Circular.
When he self-revives, EX restricts him to only Cyberse.
You can think that the restrictions of 《Mathmech Circular》are too loose because of our restrictions.
After self-revive, you can avoid the exclusion demerit by becoming an Xyz material.
In a general development, he goes first and becomes material for Primathmech Alembertian, then is sent to GY, and in the opponent's turn, he is revived with Mathmech Superfactorial and becomes material for Primathmech Laplacian, leaving the EX zone empty. You can revive yourself again on your turn when you return.

A low-level Mathmech that flies in without cutting the summoning right from your hand or GY under very loose conditions. 《Cynet Mining》can be dropped as a hand cost, and it's twice as good as one grain. Mathmech itself is a card that won't rot in the early or late game because it's easy to open the EX monster zone.
The effects that are removed when leaving the field can be avoided by removing it as an Xyz material. His Xyz Monster also has "Primathmech Alembertian" that can open EX, so the combination is very good, and Mathmech's wonderful engine... but now it's completely a part of the business trip set. It is the end of being treated. Originally, looking at Cyberse's business trip card, it had high potential and was within the range where it could be dropped with 《Code Generator》, but in that case 《Dotscaper》would be fine? And Accesscode Talker doesn't work very well, and that's why it's hard to use for business trips.
The situation changed completely with the rise of 《Mathmech Circular》. In terms of cost, GY might be the norm in this day and age, but Konami went too far. Just by drawing a circular with the first hand, you can create 3 link materials without dropping sigma and cutting off the summoning right. It's a scary story.
10 points of course. Keep an eye on Mathmech for him in the future.

A level 4 tuner who can do his Special Summon on his own from his hand and GY under loose conditions
After coming out on its own, the extras will be tied to Cybers, but if you don't attach it, it's a reasonable disadvantage because you can see that you're going to do a lot of bad things other than Cybers no matter how you think about it.
After coming out on its own, it comes with the promised exclusion demerit, but it's not a problem so far because it's mostly Mathmech d'Alembertian and defeats the demerit.
It is a disadvantage that it is a little painful because it can be used for sync and link.
If you use it as a Synchro material for Mathmech, it's a non-tuner effect, and it's an effect that doesn't activate, so it's nice to be able to apply it even if you revive it with 《Mathmech Diameter》.
Regardless if it cannot be activated, please note that it cannot be used as a non-tuner if the effect is negate by 《Skill Drain》etc.
As the name Σ (sum) suggests, he is a monster with abilities suitable for both Synchro and Xyz as a coordinator for the members of Mathmech.
Mathmech was treated badly with only two super rare spots in the pack, but it's strong enough to live up to its counterpart.
When it was first released, it was available at a low price of about 200 yen and 300 yen, but after about a month it became an expensive card of about 1000 yen.
and soon returned to the low price
However, the evaluation changed completely due to 《Mathmech Circular》
The price has gone up by about 1000 yen
In the first place, it can be said that the price has returned to a reasonable price, just because the previous evaluation was underestimated.
I just pray that I won't fall prey to the easy environment decker
In fact, the combo with 《Mathmech Circular》is atrocious, and it is possible to go all out with just one 《Mathmech Circular》without reducing your hand.
If you build Mathmech, you need 3 cards
Naturally 10 points
He was able to build it cheaply.

Mathmech tuner that can self-deploy in loose conditions. This alone is excellent.
Versatile as a Level 4 Cyber Tuner as well as a Mathmech.
In addition, it has the effect of being usable as a non-tuner, and it is better to have it than not because it can alleviate the accident of not being able to synchronize with Magma or Nabura.

"Mathmech" Tuner Monster with handy Special Summon. Moreover, he says he can do Special Summon from GY. In addition to being able to Special Summon under conditions that are looser than Photothra, he can also be treated as a non-Tuner monster when used as an S material for a "Mathmech" S monster. However, please note that if you use the Special Summon effect, it will be excluded, and only Cyberse monsters will not be able to Special Summon from the EX Deck. Further activity is expected after the new rule that "Mathmech" S monsters and "Mathmech" X monsters do not have to go to the EX monster zone.

Although it is conditional, I think that his Special Summon and self-regenerating tuner are excellent due to the effect of (1).
Only "Cyberse" can be played from the EX Deck, but all "Mathmech" Synchro Xyz are "Cyberse", so I don't think there is a problem.
I think that the effect of (2) is useful when you want to put out "Mathmech" synchro in a situation where you can only line up with other tuners.

A tuner that can come out not only from her hand but also from her GY under fairly loose conditions.
Instead, you can only get Cybers, but it can't be helped.
As usual, the demerit that is excluded can be deceived by using Xyz materials, so it can be reused.
There is an effect of 2 and it is not a loss.

There have been tuners that can easily Special Summon for a long time, but this guy is pretty bad. Or rather, he has a really strong theme for Mathmech. Why is it possible to trample opponents without using your head even though it is a mathematical motif? Everything is calculated from the beginning

My mathematics ended just around the time Sigma came out.
It has the effect of special summoning from the hand or his GY when there are no monsters in the EX zone, and the effect of treating Mathmech S monsters as non-tuners when S summoning.
Special Summon is a very easy Tuner Monster, but since there is a restriction that only Cybers can be output from EX, you will probably aim for Magma and Final Sigma. If you don't like being banished, you'll need a Cyber X monster like Laplacian or D'Alembertian.
The effect that is not treated as a tuner is active in synchronizing with Nabla and Magma. As a tuner, he is a card that will definitely play a central role in the Mathmech Deck due to the tremendous ease of Special Summon.

The effect of ① is the effect that you can Special Summon from your hand / GY on the condition that your monster does not exist in the EX monster zone. The conditions for Special Summon are not difficult, especially on the first turn, and are easy to meet. Even with [Mathmech], you can Special Summon from your hand or GY without using the summoning right, so it's very easy to use. However, with the effect of ①, this monster that he Special Summoned will be banished if he leaves the field, so be careful. Also, after activating the effect of ①, monsters other than Cyberse monsters cannot be Special Summoned from the EX Deck. However, since 《Mathmech Magma》, 《Mathmech Final Sigma》and 《Mathmech Laplacian》, which are the main of [Mathmech], are his Cyberse, this restriction is almost no problem.
The effect of ② is practically treated as a bonus since there is no scene where it can be used in particular, except when Special Summoned by the effect of 《Mathmech Nabla》.
Therefore, the main effect is ①, but it is a monster that is very easy to handle because it enhances stability by itself.

It's conditional that you don't have any monsters in your EX zone, but it's reasonably good as a Cyberse tuner that can Special Summon from your hand or GY. Also in [Mathmech], it is useful for improving stability as a means of deploying monsters without using summoning rights.
At the moment, I can't find a very useful way to use the second effect that allows you to become a monster other than a tuner, but you can get a level 8S by combining it with the same tuner, Nabla.
