"Mathmech Subtraction" Rating Score by にびぃ

One of the lesser Mathmechs paired with Mathmech Addition. In contrast to Addion, who poses like a close Zaku in a certain G*m FPS game, this is also a very cool pose with a moving illustration.
The effect is the same as Addion, targeting a monster on the field and changing the hit point of the target monster while making himself his Special Summon. This has the effect of lowering the RBI by 1000.
Basically, when you use it in the development, it is likely that you will be in the early stages of the game. Since the effect does not depend much on the field, even if it is treated as a simple business trip with the theme of "Mathmech", this one will be the winner in terms of versatility. Like Addion, even if the target disappears from the field, it is possible to make himself a Special Summon, and it is a card that is relatively easy to handle among Cybers business trips, and has an excellent status of Level 4. Even if he's tied to Cybers, he'll be something like Cyberse theme doesn't exist.
Compared to Addion, it doesn't spoil whether you attack first or second, and in the worst case, you have to pump your opponent's monsters. However, both of them are monsters that are easy to deal with and can greatly contribute to the development of his Special Summon, so it can be said that it is a pretty powerful card if you don't have to worry about having multiple copies in your hand. In terms of versatility, I will give it 10 points, one point higher than Addion.
