I've made similar claims before, but Gaia the Fierce Knight as a theme might be one of the most intricate, yet convoluted and messy archetypes in existence.
Generally, a set of cards shares some sort of naming convention, grouping of effects, or niche gimmick that ties the theme together. Even if the "theme" changes directions over time, like Red-Eyes Black Dragon or stretches across different card types like @Ignister, there are logical leaps between the cards.
…Some more than others. But it's mostly true.
Gaia The Fierce Knight is an anomaly, because it's the epitome of old school anime action. In the Duelist Kingdom arc of the Yu-Gi-Oh! manga and anime, cards and effects were way looser than they would become in later generations. It was more akin to an adventure game than a real Trading Card Game with concrete rules.
I can think of no better example than Episode 15, where Yugi launches Gaia the Dragon Champion off Catapult Turtle into a floating castle, destroying a floatation ring that falls onto his opponent's monsters, who are physically stuck in place because of other spells.
It was pretty nuts.
Gaia The Fierce Knight and its subsequent support and re-trains have emerged from pretty arbitrary backstories in the anime. We have Fusion support for Gaia because Gaia the Dragon Champion was the first Fusion Monster Yugi ever used. And we have Ritual Support because Gaia The Fierce Knight was one of the monsters used to summon Black Luster Soldier.
I could go on, but let's focus on the strongest part of the Gaia The Fierce Knight theme in 2020 – the new support from Rise of the Duelist. Namely… well, pretty much all of the cards. Originally, Gaia the Dragon Champion was pretty lame as boss monsters go – it had no effect, it only commanded 2600 ATK, and it took two Normal Monsters to Fusion Summon.
Now with Gaia the Magical Knight, Curse of Dragon, the Cursed Dragon, Galloping Gaia, Spiral Fusion and Gaia the Magical Knight of Dragons, you won't be bleeding resources just to make Fusions. While bringing out your best Fusions isn't as efficient as a single Shaddoll Fusion, Gaia and friends are much more economically viable when it comes to managing your resources.
You could probably make five different Gaia the Fierce Knight decks focusing on different things, and they'd all be wildly different. But today, we're going to OTK!

How to win? Do lots of damage! Thankfully, the modern Gaia deck isn't hard to learn. While you could go off in a dozen crazy directions with all sorts of tech, Rise of the Duelist all but forces your hand when you're trying to make the "best" Gaia deck. Simply put, you want to make Gaia the Magical Knight of Dragons and run off opposing monsters for hopefully lethal damage.
While Gaia the Magical Knight of Dragons might not look impressive, keep in mind the point of this Gaia deck is to win in damage quickly, not by amassing cards or counters to keep your opponent at bay. So first we have a Fusion Monster that gains 2600 ATK after destroying a monster in battle – a good start for a deck that wins quickly by attacking.
To help Gaia the Magical Knight of Dragons out, Spiral Fusion fuels the battle-centric strategy by giving your Gaia monster an extra 2600 ATK, and a second attack on monsters specifically. That might not wow you quite yet because of the hefty cost in materials, but consider how surprisingly easy it is to make.
Gaia the Magical Knight and Curse of Dragon, the Cursed Dragon are your Fusion Materials, because in theory a single Gaia the Magical Knight gets you the Fusion. With a clear board, you'll Normal Summon Gaia the Magical Knight, Special Summon Curse of Dragon, the Cursed Dragon from your graveyard, search Spiral Fusion and in some situations that might be enough for game right there.
Backing up a step further, the consistency continues with Galloping Gaia, Gateway to Chaos,Gaia the Magical Knight and Curse of Dragon, the Cursed Dragon becoming easy search targets from the deck. It's actually refreshing to have a solid Fusion Monster that's not ridiculously overpowered, but also easy to summon.
If only they could do a Master of Oz theme next.
If you're lucky enough to have your opponent set up the field for an easy OTK, great, you're done, sign the match slip and move on. But since life is rarely so easy, it's not often that you'll start with the perfect hand. Gaia the Magical Knight of Dragons isn't the only Fusion Monster you'll play.
The second is Sky Galloping Gaia the Dragon Champion – and yes, all the Gaia cards are named with painfully similar nomenclature. Sky Galloping Gaia the Dragon Champion isn't as powerful as Gaia the Magical Knight of Dragons, but in terms of winning in battle, it adds an option that's often overlooked in Yu-Gi-Oh: piercing damage and battle position switching.
It might seem unimportant, but combine the effects of Gaia the Magical Knight of Dragons, Sky Galloping Gaia the Dragon Champion, Spiral Spear Strike, Curse of Dragon, the Cursed Dragon, and Spiral Fusion. With relatively consistent ease, you have a boss monster that can dip into multiple attacks on monsters, monster negation in the Battle Phase, switching battle positions, piercing, and gaining 2600 ATK multiple times.
I mean… what is that going to lose to? It's nice to know that unless you're the unluckiest person in the world, you'll almost always have at least one Fusion option left after resolving Pot of Extravagance.
I have to be blunt – this deck is awesome but it hates going first, which also sums me up pretty well. Without a Battle Phase, there's very little the deck can do. Gaia the Magical Knight of Dragons can destroy cards in any Main Phase, but that's not something you can rest easy on. So if you're building the deck to go second, lean into that as much as possible.
I didn't realize until recently, but there are surprisingly lots of good cards when you're forced to go second that aren't hand traps. My first thought was simply Dark Ruler No More, but the list is quite expansive, especially now that we have Triple Tactics Talent and Forbidden Droplet from Rise of the Duelist.
Basically, this deck as I'm building it wouldn't exist without that set.
Since we only care about the Battle Phase and card economy, not much else matters. The deck comes down to fishing for combo pieces and then making sure your Battle Phase happens – so stuffing in as many draw cards and ways to shut down your opponent, even if for only half a turn, is worth it.
Pot of Extravagance and Triple Tactics Talent cover the draw power you need, but Lightning Storm, Dark Ruler No More, Forbidden Droplet, and Twin Twisters are all hugely important for cutting off your opponent from monsters and non-monster cards alike. Even if they don't garner any card economy on their own, or if you pitch a card with Twin Twisters just to hit one spell or trap, the central combo is still just a Gaia the Magical Knight away.
But if you're forced to go first, why not make arguably the best Fusion ever printed instead Red-Eyes Dark Dragoon? Since the almighty Red-Eyes Dark Dragoon is so easy to make with Predaplant Verte Anaconda, why not use it? The commitment to play it is just a measly two cards, and you'll probably only summon it on your first turn when you're going first.
As much as this version depends on Spiral Fusion, keep in mind there are tons of ways you could customize the deck, so you're not siloed into just a few Fusion Monsters. So many of the cards that connect directly or indirectly to the Gaia theme bleed into other strategies, or at the very least they're pretty open ended.
For example, Spiral Fusion can summon any Dragon Fusion, so that opens up a can of worms into different Extra Deck plays. The Gaia theme also includes weird cards such as Soldier Gaia The Fierce Knight, which can search things like Black Luster Soldier - Envoy of the Beginning, because why not? That leads into Chaos decks in general, and the list goes on and on.
While a more competitive version of the deck needs some expensive cards, virtually everything from the Gaia theme itself is dirt cheap, meaning this is one of the better casual decks to play right now if you're willing to compromise Lightning Storm. Fielding your Fusions is arguably one of the most consistent things any theme can do right now – and I'm just happy Gaia the Fierce Knight is finally a deck you can play and win with!
Just remember: beat your opponents before they beat you.
