Equipped with 《Geomathmech Final Sigma》, when fighting an opponent's monster, he drops a multiplier from the deck and his ATK is (3000 + 500) × 2 = 7000
If there is an Attack Position monster with ATK 3000 or less on the opponent's field, the opponent dies.
very simple and easy to understand
Search also has D'Alembertian, so you can easily bring it
Equipped on Final Sigma, even if you can't kill it in one hit and get killed together with Final Sigma, the effect of Final Sigma and Nayuta will increase your hand by two cards and you can use two swords.
The problem is that he's an Equip Spell, so he's easily disliked.
Any Cybers can have it, even if it's not Final Sigma, so it might be a good idea to let Accesscode Talker have it and hit him with ATK 10000 or higher.
Pin it to the Mathmech Deck and you'll probably end up drawing it when you don't want it to come, but it'll come in handy.
From the first move of the Formad Skipper, he is equipped with Nayuta and can use ATK 5300 Access Accesscode Talker, so it might be interesting to aim for it.
Due to Nayuta's effect, ATK becomes (5300 + 500) x 2 = 11600 when fighting an opponent's monster.
Remember, he can only raise his ATK when fighting monsters.
