Fabled Fiendsmith Genesys April 2026

I believe that this is close to the most optimal Fabled list you can play for Genesys Format (currently). I personally have piloted it all the way to Top 15 on the Duelingbook Genesys Ladder, which at least gives me some credibility.

For those unfamiliar, the Fabled archetype is composed of Light Fiends, the “Fabled” monsters, which should not be confused with their Light Beast counterparts, “The Fabled” monsters. These monsters are built around the discarding mechanic. Most Fabled monsters either discard a monster to summon themselves or summon themselves when discarded. They utilize their lack of a once per turn on their effects in order to swarm the field with Synchro Summons. With their newest wave of support, they now aim to control the board with their new boss monster, Fabled Levilazebul, in order to steal all of your opponent’s monsters, sometimes multiple times in one turn.

Here are the key points you should know about the deck:

• All of the newest Fabled cards are good enough that they deserve their own spotlight 
  • The Fabled Behilmoth is an incredible discard outlet for the deck. Many of your hands are centered around accessing and/or getting the maximum value off of resolving Behillmoth. He is a terrific starter for Gammajin. It is definitely one of the deck's biggest chokepoints if your opponent can negate it, as he is a HOPT. His GY effect is something you don't want to forget, as a million things can trigger it so you can extend. A common scenario is if you use Behillmoth and Kushano for Fabled Ragin to draw 2, then you use Kushano to discard a Fabled, and then banish Behillmoth to summon out the Kushano and make Crystal Wing Synchro Dragon 
  • Fabled Gammajin is one of the deck's strongest cards, and our true starter. Between Rescue Cat, Behillmoth + a 2, and a Kushano + Lurrie setup, the deck is built around ensuring that we can access this card. Gammajin easily gets us towards Levilazebul, and since the deck can produce so many Level 6s, he is great for accessing Levilazebul multiple times in a turn. His GY effect is not always the most impactful, but it does come up practically every game, and you can weave setup to get an extra draw or two.
  • Fabled Realm's Revival is a powerhouse for the deck and does everything. It can act as a starter, an extender, grind game/recoverability, and interruption. Every effect of Revival is so important, but what is slept on is the Branded Lost effect. You guarantee your Gammajin fully resolves, and if you use Levilazebul’s effect on summon you get to steal from your opponent uncontested. Thus, many hands that include Engraver/Tract will just end up grabbing Marcosia to make sure you have it. But because this deck prefers more Fabled monsters, I have stuck with only two copies. 
  • Fabled Levilazebul is what makes modern Fabled a deck, and it has warped completely around this card. He has such unique and powerful removal, which many Genesys decks cannot handle, and we definitely want to be abusing it. In Advanced, we are able to loop his soft OPT effect using the Fiendsmith cards, but we only have Treason in Genesys. Because of that, he really shines in this deck when you are going second. You can frequently Summon and re-Summon him in one turn, stealing your opponent's monsters then potentially using them in order to make another copy to steal even more. In combination with Realm's Revival, he is unrespondable when you use his effect on Summon, making breaking boards a piece of cake. And even if it looks scary  to shuffle him back with his grave effect, you will be doing it more than you would expect. His GY effect is part of what gives the deck such good extension and grind game, so you always want to make sure you guarantee you can summon this card.
  • Quick shoutout to the OG Fabled Kushano. His non-OPT GY effect carries so many games and combos on its back. A hand that gets him into rotation has a million more options, since keeping a Fabled in hand after discarding lightens the load of burning through resources in a discard-based deck. An example would be if you make Fiendsmith's Lacrima. You can either summon back Gammajin, or you add back Fabled Krus, pitch it with Kushano, and you're at the same board state but went +1 in card advantage. 

• Both Fabled Levilazebul and D/D/D Wave High King Caesar are both incredibly strong pieces of removal in Genesys format, especially this meta. I'd consider Caesar the only pointed card that is mandatory for the deck. Caesar is especially good because it counters Illusion Gate, currently a very popular board breaker. Most hands going 1st aim to end on at least these two cards.
•  
• I would always be maxing out on Fiendsmith and the Mutiny package. Any hand that has access to Fusion Summoning has infinitely more options in what you can do, both going 1st and 2nd. The Fusions they summon, notably Lacrima, serve as great extenders, and between Engraver and Mutiny, they separately allow grind game to the deck.
• Speaking of Mutiny in the Sky, Buio the Dawn's Light is quite specific when you want to summon it. In order to summon from hand, you must negate the effects of a Fiend monster. This means if it's already negated (like a stolen monster from Levilazebul) or if your opponent destroys or negates your target's effects in response, you will not be able to summon Buio.
•  
• The old Fabled monsters have mandatory effects, which means that if you discard a Behillmoth and Krus to summon Gammajin, Krus must be CL1 meaning that you cannot chain block Gammajin.
• Fabled Soulkius, The Fabled Nozoochee, and Fabled Treason are all unfortunate but necessary bricks. Bridging straight from Gammajin to Levilazebul with Soulkius is important. Nozoochee is a garnet if you draw exactly Rescue Cat alongside it, and Treason is a trap. Although you can side out Treason and Nozoochee with Rescue Cat when going 2nd.
•  
• When side decking, if you want to put in more than 9 non-engine, you can side out Treason as well as the Rescue Cat package (Cat + Nozoo). It is important to know to do this againt decks you need to draw non-engine against, or decks that you know can easily kill Rescue Cat if you try to Summon it.
• Speaking of the side deck, Illusion Gate will likely be replaced with Dark Hole after Gate gets pointed. It is a noticable difference, but it will still do the trick.
• In the side deck, if floodgating with Gravity Collapse isn't your thing, you can replace it with Mannadium Reframing. This may be correct anyways, since a lot of decks naturally play around Collapse, and many breakers kill the deck. If you were to do this, you want either in the side or Extra Deck a copy of Visas Amritara so you can search out this negate.
•  
• The Extra Deck is very tight. Basically every card in it will come up every couple of games. The only exception to this is Snake-Eyes Vengeance Dragon. It is currently the only flex spot, as I mainly have it in there for the Kewl Tune matchup in addition to niche scenarios with Accel Synchro Stardust Dragon. 

Weaknesses

Fabled has many strengths to it, but it is held back by the fact that it loses to every popular piece of non-engine frequently being played.

• Handtraps like Mulcharmy Fuwalos practically murder us, Nibiru, the Primal Being can be played through but can still be pretty devastating, and a well-timed D.D. Crow or Skull Meister could kill a turn.
• Practically every breaker can just wipe out a board, including Dark Ruler No More, Book of Eclipse, Lava Golem, Ultimate Slayer and Gordian Slicer especially. You can play around it a litle by purposefully putting Levilazebul in GY with Treason set, but it's not advised.
• Dimension Shifter and Dimensional Fissure ANNIHILATE this deck. You need a very specific hand to even play through it somewhat, as this list does not have anything to deal with a DiFi besides drawing Twin Twisters
• Also, sometimes this deck does kind of lose to itself. The deck has many, but if your hand does not have access to a Tuner, than there's really nothing you can do. Though I guess that's any Synchro Deck. There are a bit of awkward hands that take a good amount of skill to figure out the lines to. 

Conclusion

I believe that Fabled has a lot of potential in Genesys. I do think it is solidly a Rogue deck, but it can catch many by surprise. The deck can be incredibly difficult to pilot well, but it is so rewarding breaking through a board while looping Levilazebul, Kushano, and Krus.

If you actually read all of this, thank you for listening to my rambling and I hope that this list will guide you well. Here's a link to the Fabled Discord Server if you have any more questions.
