Notes & Combos

this deck is so firewall

i hate playing bricks for one omni negate and enigmaster can get mathmech multiplication out of your hand for the otk + can lock decks out of access to an important monster

your optimal endboard is firewall + allied code + transcode + heatsoul + superfac

this leaves you with: 1 spell/trap negate (firewall send desavewurm) 1 omni negate + banish (allied code) target protection (transcode & allied code) 1 destruction protection (defenser in grave; exclusive to firewall) 1 target dodge into trap negate + banish (linguriboh in grave) 2 draws (heatsoul) 1 handrip + optionally 1 monster and 1 spell removal (superfac > laplacian) 1 omni negate (laplacian) 1 non destruction non bounce non banish monster removal (firewall send enigmaster)

pray you have a maxx c out; red reboot will stop high impact handtraps like imperm and impulse while letting you play into boards with one off omni negate traps like orcust

keep an extender in hand at all times to avoid getting stopped by nibiru

you can get full endboard if you go uninterrupted with mathmech circular (who can be searched off of cynet mining) or firewall defenser (who can be summoned off of bitron)

i play bitron as another dark monster to summon off of AI connect (which is busted) as well as a 2nd firewall guardian because drawing guardian is actually so bad its basically a garnet but instead of turning off brilliant fusion it turns off 6 different cards AND prevents you from getting full powered endboard

as always firewall gets you the otk of doom, accesscode isnt as great cause i dont have room for update jammer but it helps for otk when you dont have firewall and arent under circular lock

last thing normally i play subtraction, but liger dancer is immune so we have to inject firewall with addition meth to otk (just do combo under wicckid and get defenser in grave before ROCKING)

^ includes circular full combo and full combo through nibiru, missing defenser full combo, but you just swap the places of circular and defenser in the combo (send diameter instead of sigma > splash mage summon diameter to trigger circular and search superfac > xyz into alembertian to search the addition/subtraction) otherwise theres no difference.
