Master Duel @Ignister Code Talker

TLDR: @Ignister with added consistency and variety by means of Code Talker support.

You could go for the usual 1st turn 6000 ATK Arrival or 5000 ATK Arrival + Cyberse Quantum Dragon (Gatchiri-buffed) or 2nd turn Accesscode + Update Jammer OTK (preferably Gatchiri-buffed and/or backed by Cynet Optimization), but with the assistance of the searching power of Code Talker support.

To properly execute an @Ignister combo, one should be aware of the relevant functions of each card.

Achichi, the red blob - search out other @Ignister combo monsters (usually Pikari)

Pikari, the yellow blob - search out @Ignister spells (usually AI Meet You), change the level of another @Ignister monster to 4 (for Xyz Summoning Light Dragon)

Bururu, the green blob - send an essential monster to the GY (usually Gatchiri), Special Summon its fellow material after a Synchro Summon

Doyon, the violet blob - retrieve an essential monster from the GY (usually the Gatchiri sent by Bururu), retrieve an @Ignister spell from the GY after being used for a Cyberse Link Summon

Hiyari, the blue blob - free Special Summon from the hand if another @Ignister monster is on the field, tribute another Cyberse monster to search out high-level @Ignister monster (usually Gatchiri)

Gatchiri, the spiky one - Special Summon from the hand by negating a Cyberse monster's effects (use it on something that had already used its effects), protect all your Cyberse monsters from card destruction once (counted separately per monster), make one of your face-up monster unaffected by your opponent's card effects until the end of your opponent's turn if sent to the GY (EXTREMELY IMPORTANT EFFECT)

Danmari, the spooky violet one - negate attack while your @Ignister monster battles (handtrap), works as a targeted omni-negate if you control Arrival while this is in your GY

Micro Coder, the yellow-green one - search out Cynet spells (usually Cynet Codec)

Code Generator, the orange one - send an essential monster to the GY (usually Gatchiri)

 

There are many combo routes (especially with the added Code Talker support), so I'm only gonna discuss the pure @Ignister way to 6000 ATK Arrival.

@Ignister monster (usually Achichi or Pikari) >> Dark Infant (search out Ignister AILand) >> @Ignister monster (usually Achichi or Pikari) >> Cyberse Wicckid (skip if you already have Bururu in hand) >> SPECIAL SUMMON @Ignister monster in Wicckid's link arrow (don't use Doyon if possible) >> Splash Mage (don't use effect before summoning another @Ignister) >> Bururu (send Gatchiri or Danmari to the GY) >> Dark Templar (summon on the right Extra Monster zone) >> Doyon (summon on the zone below the other EMZ, retrieve Gatchiri from GY) >> Gatchiri (summon to the leftmost zone by negating Doyon) >> Dark Infant (summon to the leftmost link arrow of Dark Templar by using Doyon; choose DIVINE element; the following chain MUST be Doyon > Dark Templar > Dark Infant; make sure to retrieve different elements with Dark Templar's effect) >> Wind Pegasus (this is to set up your GY with this card, Pikari will return to the field via Bururu's effect) >> 6000 ATK Arrival

For 5000 ATK Arrival + Cyberse Quantum Dragon (Gatchiri-buffed), use Transcode Talker instead of Splash Mage, use Quantum instead of Pegasus, summon Splash Mage and the monster from its effect for Link-6 (2 link arrows from Splash Mage, 1 from every other monster except Quantum), and target Quantum with Gatchiri's effect.
