I don't think one card has ever received as much attention in advance of its TCG release as Crystron Halqifibrax. Literally not in the entire history of this card game, and I'm not being hyperbolic. For some perspective, Halqifibrax was released in the OCG back in November 2017; we've spent nearly two and a half years watching the card wreak havoc on foreign soil, and many players were quite happy to see its TCG release delayed again and again.

If you've been paying attention to Yu-Gi-Oh! over the years, then you'll have noticed that free summons from the deck are typically pretty good. Even the old school recruiters like Mystic Tomato and Mother Grizzly saw play for years before evolution took over introducing cards like Emergency Teleport and Isolde, Two Tales of the Noble Knights – cards that were like raises and re-raises of the stakes of Special Summoning in their respective eras.

While Crystron Halqifibrax can't summon everything from your deck, the ability to kick out Level 3 and lower Tuners casts a tremendously wide net. Attribute and type specific recruiters settled into niche roles over time, but the ability to summon almost any Tuner from your deck opens up a can of worms that's literally too big to discuss in succinct ways.

If someone tells you they have a Crystron Halqifibrax combo, that's about as descriptive as "I have a combo where I activate card effects." Is there a best Crystron Halqifibrax combo? Maybe. Sure. What would the term "best" mean in that case? "Tuner" is such a nebulous subsection of cards that Halqifibrax combos invariably look different for every deck playing the card. It's powerful, sure, but how powerful will depend on what it's doing, and we can't just lift combos from the OCG because many of the cards that made Halqifibrax so broken there, are already restricted here.

So where do you play this thing? And where does it make the biggest impact? That's the question I want to tackle today. Don't throw the card away quite yet, even with the most recent Forbidden and Limited List. Crystron Halqifibrax is still worth its weight in gold.

How Many Combos Are There? Yes.
One of the reasons Crystron Halqifibrax carries so much hype is that it's so easy to summon. It's not the most generic Link Monster ever, but the question of can you summon it just comes down to can you field a Tuner? If the answer is yes, then your Crystron Halqifibrax is ready to go!

Before I dig into some of my favorite combos, let's talk about the fact that you can summon Crystron Halqifibrax in virtually any deck. Seriously, pick a deck and you'll probably find some on or off-theme way to get Crystron Halqifibrax onto the table.

Let's start with Burning Abyss. Not only can you make Halqifibrax happen by Special Summoning Rubic, Malebranche of the Burning Abyss and any other Burning Abyss monster, but doing so won't take up your Normal Summon. If you have Tour Guide From the Underworld, there's Crystron Halqifibrax too.

Normal Summon Righty Driver… Special Summon Lefty Driver… oh look, Crystron Halqifibrax. Normal Summon Deep Sea Diva, bring out any Sea Serpent and boom, Crystron Halqifibrax again. You can use Genex Undine to make stuff more complicated, using Crystron Rosenix, Link Spider, and Genex Controller along the way.

What if you're playing Dinosaurs? Sure, Normal Summon Souleating Oviraptor and yard Miscellaneousaurus, then banish that for Jurrac Aeolo. Playing Plants? Lonefire Blossom is a 1-card Halqifibrax, too! How about Scraps? Normal Summon Scrap Recycler and send Mecha Phantom Beast O-Lion to the graveyard.

Guess who's coming to dinner! (It's Halqifibrax.)

What if you play Instant Fusion or Emergency Teleport? There are Tuner options for that as well. Or go ahead, be bold and use that Unexpected Dai for Tune Warrior. Even bad options are pretty alright when your end play is Crystron Halqifibrax.

Heck, you can even Normal Summon Sangan, make Salamangreat Almiraj, then search and Special Summon Crusadia Arboria for it. Or if you have two Warriors, or you're playing Six Samurai or Noble Knights, keep in mind that Isolde, Two Tales of the Noble Knights sets up a bevy of Warrior Tuners in your graveyard! The possibilities are almost infinite.

Loop Your Opponent's Hand For 5 Cards With Mermails
If I made a comprehensive list of every Crystron Halqifibrax combo possible, I think you'd literally have two or three birthdays before you finished reading it. COVID-19 would be over, tournaments would be back and the world would be a better place. But that's a little impractical, so today I'm highlighting some of my favorite plays from decks that have seen competitive success instead; strategies that I enjoy playing myself! First, let's take a look at our fishy friends the Mermails. This one's kind of simple, and you just need two cards to begin.

- Start with Mermail Abyssteus, pitching Atlantean Dragoons to search Deep Sea Diva and Mermail Abyssgunde

- Normal Summon Deep Sea Diva and Special Summon Neptabyss, the Atlantean Prince. You'll send Atlantean Dragoons to the graveyard and search another Dragoons, netting a Mermail Abyssmegalo

- Link Deep Sea Diva and Mermail Abyssteus into Crystron Halqifibrax and Special Summon Jet Synchron from your deck.

- Next up, Special Summon Mermail Abyssmegalo by pitching both Mermail Abyssgunde and Atlantean Dragoons, triggering several effects along the way. Mermail Abyssgunde Special Summons Mermail Abysstues from your graveyard, while you search Moulinglacia the Elemental Lord and whatever Abyss-scale your heart desires.

Now that you have five Water monsters in the graveyard, Special Summon Moulinglacia the Elemental Lord and make your opponent drop the first two cards from their opponent hand. Synchro Summon PSY-Framelord Omega with your Jet Synchron and Mermail Abyssteus, then pitch your Abyss-scale spell to bring back Jet Synchron and make Trishula, Dragon of the Ice Barrier! Your opponent loses Card Number 3…

Now the weird thing about this hand loop is that part of it's played on your opponent's turn. In your opponent's Standby Phase you'll use PSY-Framelord Omega to take your banished Jet Synchron and place it back in your graveyard, then in their Main Phase you'll banish Omega to banish another card from your opponent's hand. At that point you'll follow up by banishing Crystron Halqifibrax for Desert Locusts, a funny little Synchro that also forces your opponent to discard!

The best part, if you needed another excuse to like the deck, is that you'll still have three other cards in your hand! It's tough to imagine a better result from a single combo, looping your opponent for five cards in one turn.

Make Cosmic Blazar Dragon In ABCs
ABC-Dragon Buster decks took a big hit in the new format, but I've developed a bit of an obsession with them in the past few weeks. And with Union Driver coming out in Eternity Code, the combos just get that much crazier. I'm also a huge fan of Synchro Summons, so consider this wacky play…

- Start with Union Hangar, Silver Gadget, and B-Buster Drake - all three are really common cards in the ABC deck, so it's not a tough hand to put together

- Activate Union Hangar, searching out C-Crush Wyvern. Normal Summon your Silver Gadget and Special Summon Crush Wyvern from your hand; Union Hangar gets Union Driver, one of my new favorite cards. You'll use Union Driver's effect to equip the Wyvern with Torque Tune Gear, then Special Summon it right away.

- Guess what's next? Crystron Halqifibrax!

- Summon B-Buster Drake from your hand with C-Crush Wyvern's effect, and use Halqifibrax to summon Jet Synchron. Sync B-Buster Drake with Jet Synchron for T.G. Hyper Librarian, and B-Buster Drake searches A-Assault Core from your deck.

- Bring back your Level 1 Tuner by pitching Assault Core, then Tune it with your Silver Gadget to make a Jet Warrior, drawing a card and bouncing a card on the field, just in case you need to! Suddenly you control two Level 5 Synchros and all the materials for ABC-Buster Dragon arae in your graveyard

Just like the Mermail combo you'll use Crystron Halqifibrax's effect during your opponent's turn, but this time your Tuner Synchro of choice will be Formula Synchron, netting you two more draws – one from Formula Synchron and one from the Hyper Librarian. Formula Synchron also works during your opponent's Main Phase, so boom, there you have it: Cosmic Blazar Dragon!

Score A Silly Alternate Win Condition
You ever have those ideas that are so crazy they shouldn't work, but after testing them out, you've found out your original idea isn't that bad after all? I won't tout this as the combo to end all combos, but bear with me - against most decks, this 2-card combo basically seals the deal.

I only say "2-card combo" because you'll need to discard a monster with Prepadplant Orphys Scorpio, but Lonefire Blossom plus "monster" is about as basic as it gets.

-First, Normal Summon Lonefire Blossom and tribute it to Special Summon Prepadplant Orphys Scorpio

- Discard the monster in your hand to Special Summon Predaplant Darlingtonia Cobra, which searches Instant Fusion. Use Instant Fusion to Special Summon Sea Monster of Theseus

-Link Summon Cherubini, Ebon Angel of the Burning Abyss and yard Carboneddon from your deck. Banish Carboneddon to Special Summon Petit Dragon

-Then, Link Summon Crystron Halqifibrax with Sea Monster of Theseus and Cherubini, Ebon Angel of the Burning Abyss, and use it to Special Summon Red Rose Dragon from your deck

-Synchro Summon Garden Rose Maiden with Petit Dragon and Red Rose Dragon, netting three cards. Garden Rose Maiden adds Black Garden from your deck to your hand while Red Rose Dragon Special Summons White Rose Dragon from your deck and searches Frozen Rose

-Activate Black Garden, and for simplicity's sake, I'll just say the next five Summons give your opponent five Tokens, specifically "Rose Token" monsters

-Link Summon Cross Sheep with Crystron Halqifibrax and Garden Rose Maiden, but then banish Garden Rose Maiden to revive the yarded Red Rose Dragon

-Synchro Summon Power Tool Dragon with Red Rose Dragon and White Rose Dragon, revealing three copies of Re-Fusion, adding one to your hand. Additionally, White Rose Dragon sends Fallen Angel of Roses from your deck to your graveyard

-Activate Re-Fusion, reviving Sea Monster of Theseus to a zone Cross Sheep points to, reviving Lonefire Blossom in the process

-Activate Frozen Rose, sending Cross Sheep to search Rose Fairy, a monster that Special Summons itself when searched from the deck

-Tribute Lonefire Blossom with its effect to Special Summon Spore from your deck, then Synchro Summon Stardust Dragon with Spore and Power Tool. Synchro Summon a second Stardust Dragon with Rose Fairy and Sea Monster of Theseus

-Banish Fallen Angel of Roses with Spore to make it a Level 8 monster, then stack all three Level 8 monsters for Number 88: Gimmick Puppet of Leo

I can hear you laughing now, but reconsider Number 88: Gimmick Puppet of Leo's effect. Since your Field Zone technically isn't in your Spell & Trap Zone, Black Garden won't restrict Leo's effect from working. In three turns, you've won the duel.

Sure, your opponent could just Link away Tokens for Link Monsters, but think about how many decks don't play generic Links anymore. Outside of Beat Cop of the Underworld, which has largely fallen out of fashion, most decks can't do anything with five Tokens. Most nearly-generic Link monsters stipulate no Tokens or require monsters with unique names, and the Tokens are Level 2, so Linkuriboh won't work.

As long as you keep Number 88: Gimmick Puppet of Leo in defense and don't get hit with Raigeki or a Tribute Summon, you've just won a free duel. Not bad for a crazy combo, right?

Unleash The D/D/Ds
There are tons of other decks that could use Crystron Halqifibrax, but let's revisit a strategy that was the bees' knees for a matter of minutes in the TCG: Different Dimension Demons. Because so many of the D/D/D cards are so interchangeable with searching, summon, and revival effects, there are lots of different ways to do this combo. But for sake of ease, let's use an example where you start out with a few cards that you'll play multiples of: D/D/D Oblivion King Abyss Ragnarok, D/D/ Swirl Slime, D/D/ Necro Slime, and D/D Lamia.

I joke about getting a headache wrapping my head around some of these plays but seriously, there are countless ways to "start" this combo depending on your opening hand. I'm trying to not give anyone a brain freeze by simplifying it, and while the play needs four cards there's tremendous wiggle room; translation, it's more reliable than it looks.

- First, Fusion Summon D/D/D Flame King Genghis with D/D Necro Slime and D/D Swirl Slime

- Then Normal Summon D/D Lamia, and play D/D/D Oblivion King Abyss Ragnarok as a Pendulum Spell

- Link Summon Crystron Halqifibrax via D/D Lamia and D/D/D Flame King Genghis

- Special Summon another Lamia from your deck with Halqifibrax. You're going to see a lot of D/D Lamia in this combo!

- D/D/D Oblivion King Abyss Ragnarok triggers to let you revive D/D/D Flame King Genghis from your graveyard, then you'll banish Necro Slime and Swirl Slim to summon another D/D/D Flame King Genghis from your Extra Deck

- That triggers your first Genghis to bring back D/D Lamia

- Synchro Summon D/D/D Gust King Alexander with Lamia and your first Ghengis, then tune the second Lamia and Ghengis to summon Odd-Eyes Meteorburst Dragon!

- Odd-Eyes Meteorburst Dragon Special Summons the D/D/D Oblivion King Abyss Ragnarok you played as a Pendulum Spell, and D/D/D Gust King Alexander brings back D/D Lamia, the Tuner that just won't quit

- To keep the combo going, the effect of your D/D/D Oblivion King Abyss Ragnarok now triggers to Special Summon back D/D/D Flame King Genghis; that works because Abyss Ragnarok is now a monster, not a Pendulum Spell. Then you'll make D/D/D Cursed King Siegfried with Alexander and Lamia

- Next, send your Flame King Genghis to the graveyard to Summon - you guessed it - a D/D Lamia from your graveyard. Combine Odd-Eyes Meteorburst Dragon and the trusty D/D Lamia to make Crystal Wing Synchro Dragon, leaving you with an extremely scary board of Crystal Wing Synchro Dragon, D/D/D Cursed King Siegfried, Crystron Halqifibrax and D/D/D Oblivion King Abyss Ragnarok (who's just kinda hanging out).

Sure, your Halqifibrax might not look so impressive with company like that, but keep in mind that you can still pop it off for a Synchro on your opponent's turn. Granted you might not need to, since Crystal Wing and Cursed King Siegfried are your real heavy hitters.

What combos are you most interested in? I know you probably had an aneurysm reading that last combo, but it just goes to show you how many possibilities there are from one card now that we live in a post-Halqifibrax world. Give it a shot yourself: experiment with your favorite combos and know you can put Crystron Halqifibrax into basically any deck!

Just remember: beat your opponents before they beat you.
