Mathmech Neo Tempest Terahertz

This deck aims to create Neo Tempest Terahertz with super factorial with at least a Diameter in the gy along with 2 other math mech monsters with different names so you can summon them Primathmech Laplacian with a negate and for 1 monster, spells removal and 1 hand discard. You can send Desavewurm (Negate while you control a link 4 or higher) on your turn and on your opponent's turn Merologic Aggregator to spot negate any card on the field, ( this is slow, so, please send it in prediction of a card on the field )

Neo Tempest is fragile, so you can use Trancode talker to protect it, and if you draw in a firewall defence you can also get cynet conflict. Neo Tempest can get pretty big fast, by turn 3 you can have ~8000 attacks (please be aware because Neo Tempest can attack multiple times up to the number of attributes it has), so on turn 3 before battle faces it is recommended to send something other than a dark attribute. 

Siding:

I was thinking about siding firewall guardian for going second, as it helps you get an extra body on the field when it is link summoned instead of Phantom. I also have sided Dark ruler no more to break big negate boards. Furthermore, as Droll is being main decked now, Crossout can help negate the problematic hand trap for this deck. 

How to summon Neo Tempest:

All you need is 3 cyber monsters on the field (you can do this through the standard Mathmech Circular line), make splash sage, summon a cyberse using splash sage's effect, then go into transcode talker, the active effect of transcode talker, then link-off into Neo Tempest, dump Desavewurm and Neo Tempest and 2500 attack. 

Game 2:

going second I tend to remove Cynet conflict and replace it with more hand traps. going first against a spell-reliant deck, i.e. branded, I will remove ghost orge and kaiju for 3 Anti-spell Fragrance to cripple the deck. 

Can't make Neo Tempest, Time for plan B:

Try at least get to 2 cyberse monsters on the field, so you can go into splash sage and then active effect summons a cyberse, and then link into Heatsoul. IF you drew conflict, it still should help you as Heatsoul is a code talker monster.
