This deck focuses on Eldlich while adding a bit of backbone using the Mathmech Engine. Circular adds a new take on Mathmech, expanding it's combo into just a single card. Your usual endboard ends out with Superfactorial, Heatsoul, some set traps and hand traps. The Mathmech combo of this deck can be utilized into a lot of Cyberse decks. Here is how to perform it:
1: Circular effect, send Sigma to the graveyard, special summon circular
2: Sigma effect, special summon itself
3: Circular triggers off of Sigma's summon, adding Superfactorial
4: Xyz into Alembertain, Alembertain adds either Addition or Subtraction
5: Special summon the added monster
6: Link into Splash Mage, special summon any monster
7: Link into Heatsoul
Heatsoul draw one card
Set any traps you drew from the draw phase or Heatsoul and pass turn!
The beauty about Heatsoul is that you can draw during your opponent's turn, giving you either more hand traps for your opponent to face or giving you follow-up. Superfactorial can make Laplacian, which can send a card in hand to the graveyard, a monster they control to the graveyard, or a spell and trap card they control to the graveyard. It's a great way to troublesome cards from the field while also removing any possible extenders or follow-up in their hand. This deck can also OTK utilizing Update Jammer, which can make Accesscode be able to attack twice. Since you're only able to attack with one monster when using Circular, this is excellent. If you want to see more Mathmech, you can add in a second Nabla to get the Mathmech engine to pop out more. Cynet Mining can discard your Eldlich cards, making both your engines synchronize by discarding a card you want to hit the graveyard to add Circular. This deck doesn't fair very well against cards like Dimension Shifter. Mathmech Eldlich is a interesting deck using Mathmechs to draw into more pieces, hand traps, or anything else while also granting the removal of 3 cards and follow-up. When it comes to Mathmechs, the sky is the limit.
