"Mathmech Addition" Rating Score by にびぃ

One of the low-level Mathmechs with a very cool standing figure.
Targets 1 monster on the field and has the effect of increasing itself to his Special Summon and the target monster's RBI by 1000. It's okay to target monsters on the field, but if you can't remove the opponent's monsters, you want to use it on your own monsters if possible.
Like Mathmech Subtraction, which lowers RBI by 1000, it can't attack on the turn it's played, but since it's used as material, you shouldn't worry too much about it. And here, it's a bit of a arbitration issue, but Addion and Subtra are processed in the order of "targeting 1 monster on the field, changing the target's RBI after ssing itself". In this case, what happens if the target monster disappears by chaining some kind of monster removal effect to the effect of Addion and Subtora? In this case, the Special Summon will be performed without any problems, and only the effect of the RBI change will be misfired. 《Gatchiri @Ignister》exists among cards with hand trigger effects similar to Addion and Subtra. This card is processed in the order of ``target one of his Cyberse Effect Monsters on your field, negate the target effect, and then ss yourself''. In this case, if there is no target, the target that negates the effect will misfire and the confidence will not be able to his Special Summon. In general, this card and Subtra are very flexible. It's nostalgic now that in the early days of Master Duel, players who didn't really understand the target's ruling would waste removal interference on this effect.
However, it is difficult for him to go on business trips other than Cyberse because he is bound by Cyberse's specialty. However, since Cybers has many strong themes such as @Ignister and Accesscode Talker that have excellent development power, it would be good to use them to expand the development of those themes. Especially with the appearance of 《Mathmech Circular》, it is quite easy for him to go to Mathmech.
However, you can't even activate the effect if there are no monsters in the first place, so you need to be careful about that.
