Master Duel @Ignister

Disclaimer: Due to lack of resources, my real Master Duel deck only has two copies of Crossout Designator and no Nibiru, while having two copies of Doyon and Bururu instead.

I only used a maximum of two copies for staples since I have to balance between survival and potential bricking.

If you're going first, you could go into Firewall Dragon Darkfluid with at least two counters and protection (Gatchiri or Light Dragon). If you have a good hand, you could send Water Leviathan into the GY instead of Gatchiri with the Bururu effect, or use AI Love Fusion to bring out Earth Golem as Link material to provide more counters. Along with handtraps and/or quick-play spells, you could shut down many decks provided that they don't have Lava Golem or Kaiju.

My past iteration used Mekk-Knight Crusadia Avramax + Cyberse Quantum Dragon instead of Darkfluid. However, I was traumatized by Tri-Brigade Lyrilusc in the ladder (damn you Shuraig and Draco Future), so I opted for another boss monster. Arrival won't cut it since it is vulnerable to decks that can easily bring out beatsticks like Utopia and even Kaiju (it is expensive to bring out that you can't afford to lose it).

If you're going second, you could try to circumvent their defenses to bring out Splash Mage + Update Jammer into Accesscode Talker. You can use Transcode Talker instead of Splash Mage at your own risk, but keep in mind that 4300*2 can win you the game as much as 5300*2. Although, if you need more ammunition for Accesscode, you could go for Transcode.

You need to be careful about the placement of your monsters, especially for Dark Templar and Dark Infant. Ideally, Dark Templar must be in the right EMZ with Dark Infant summoned in the leftmost link arrow. The left side of your Dark Infant must also be empty since it will move to that zone after chaining with Dark Templar in order to make way for the special summoned monsters from the GY.

Using the effects of Dark Templar and Dark Infant, you can special summon 3 monsters from your GY. It is recommended that you choose Bururu + Pikari (don't use effect yet since it is negated) + 1 (preferably Doyon). Synchro Summon Wind Pegasus (use this as material for Darkfluid since this is very useful in dealing with most invincible monsters even when it is in your GY) using Bururu and Pikari. Pikari will then come back to the field via Bururu's effect. If needed, you can use Pikari's effect to change the level of the other monster to 4 (unnecessary if you have Doyon), then Xyz Summon Light Dragon. Use AI Love Fusion to Fusion Summon Earth Golem using Dark Infant (don't expose a 500 ATK Link monster in the open) and another monster.

Note: In another iteration, I would've brought out Cyberse Quantum Dragon instead of Wind Pegasus and Dark Templar + Dark Infant into Avramax, but it is vulnerable to many plays without the means to counter.

The most common sequence is Dark Infant >> Cyberse Wicckid (search out Bururu, but skip this if you already have it) >> Splash Mage (don't use its effect if you plan to go into Transcode) >> Transcode Talker (skip this if you used Kaiju) >> Dark Templar. There are many routes and detours to the combo, however, going into Dark Templar while having a monster that can be summoned and Dark Infant in your Extra Deck is the most ideal scenario. One thing to note is that you are expected to utilize Achichi, Pikari, Bururu, and Doyon. Doshin and Hiyari are just luxury monsters that can extend your combo or help you in a pinch.

If you find yourself in tough spots, don't ignore the other @Ignister monsters since they have very useful effects.

Use Fire Phoenix when you don't have enough cards to continue the combo, since it can float and has a monster destruction effect (during the battle phase, banish Achichi from GY if necessary).

Use Wind Pegasus to clean backrow as well as provide a "revenge" mechanism to your board (even in the GY).

Use Light Dragon to clean monster zone and resurrect a link monster as soon as you deal battle damage with other Cyberse monsters (works in the battle phase).

Use Water Leviathan to reduce a monster's attack to 0 while returning all your link monsters from the GY to the Extra Deck (the other effect doesn't work against most decks since only monsters with 2300 ATK or less are returned to the hand).

Earth Golem is usually just fodder for Darkfluid but it could still be useful in some scenarios.

The best thing about them is that you can directly resurrect them with AIdle Reborn and FAIghting Spirit, or return them to the hand with Doyon (you can also retrieve related spells with Doyon's effect in the GY). However, if you plan to make use of Dark Templar from the GY, don't resurrect it since it can't be placed in the EMZ this way, instead use Doyon, Water Leviathan, or Doshin (if AI Love Fusion is still in the deck).

If you used Kaiju, don't go into Transcode Talker since it won't activate its effect and you'll end up wasting your combo potential.
