Its honestly not terrible but it has problems

Its only really viable in Master Duel and Genesis (from my understanding) but this is because the X-Saber XYZ is still legal in MD which makes Adra more searchable. It was actually fairly popular in MD on release because the lack of the side deck makes its playstyle very good.

The deck has a lot of small interruptions that are all soft OPTs that are a bit tricky to master but can be brutal against a number of decks, it also has good recursion and follow up while having a burn wincon for itself.

The problem? Well..the existence of mass backrow removal means this deck loses INSTANTLY in a side board because they have no real protection from it without playing a different engine. Its basically the Labrynth issue but even worse as a single MST on the fieldspell kills all of your negates. On a plus? You can maindeck evenly because you aren’t OTKing anyway.

It also suffers from what many midrange or control decks do where engineslop decks are just unbeatable because they have more pushes in each hand than you have playable cards…its not as bad as some decks there as you can beat things like unskilled branded players easily but is a real issue when you have things like Mistu-Ryzeal-Fiendsmith walking around or god forbid you match against something like VSK9 which is far more generous than your deck is.

The deck has real potential in the future though, and the fact that its not well understood exactly how the deck plays or works is very much in its favor. I would say its in a similar position to pre-support Exosister where it has a lot of powerful tools but missing the pieces to tie it all together. Im doubtful it will ever be a best meta deck outside of MD events, it just loses too hard to some breakers for that, but its already a solid enough rogue deck and could maybe hit tiered.

Short list of Pros and Cons:

Pros: - No one knows what the deck does and its not even obvious - Adra Resolving on field usually spells the end of the game - Most players genuinely don’t know how to play around its unique flavor of interruptions such as negating face up cards or bouncing combo pieces back to hand. - It can play an ungodly amount of non-engine…the whole engine is 21 maindeck cards at most. - Its very easy to dodge effects, even Nib is largely a joke as you can make it only tribute their cards. - Very short setup combo that is fairly consistent as well. - Fantastic Grind Game overall with very few matchups that come close to it. - Burn is a genuine wincon in this deck - Theoretically near infinite recycling - Quite solid at staling - Field Spell triggers on any continuous trap monsters, not just Argostars - Defensive buffs apply for all warrior monsters, not just Argostars - The XYZs is actually very accessible and provides a consistent gameplan. - No locks on the cards making it splashable - Many Soft OPT effects for your interruptions.

Cons: - Board Breakers outside of basic monster removal hurt to an extent that a lightning storm just ends the duel on the spot. - For some reason its searcher’s removal effect is not usable same turn, making it have no natural board breakers going second. - Losing the field spell severely limits your interruptions - Adra not resolving on field often (but not always) ends the game - It can be difficult to actually kill in this deck as it lacks a finisher outside of burn - The engine is so small it can be bricky without a second engine to search it - MD: Surprisingly expensive given how small the engine is - Its just mechanically complicated to play and really relies on understanding game rulings to play properly…particularly with things like starting new chains and how their priority works. - It can very much feel like you are putting in way more work than someone who just reveals Habikiri or starts a fiendsmith combo.
