Mekk-Knights have had impressive staying power since their debut in 2018.

I've written about Mekk-Knights plenty of times in the past, including a build earlier this year that dumps your opponent's hand and Extra Deck straight into the graveyard! But this week is a little different because I'm dropping three builds: an updated look at Invoked Mekk-Knights that's super competitive this format, a pure build, and a bonus Crystal Beast hybrid.

Need A Go-Second Deck? Aleister Brought Some Friends

Invoked Mekk-Knights are a fantastic go-second strategy this format that can rack up huge card advantage without relying on fragile combos.

The deck shares the same space as other tempo-oriented strategies like Dogmatica, Altergeists, and Subterrors, which gives it some key advantages against combo decks like Dragon Link and Infernoble Knights. Chiefly, Invoked variants aren't as weak to disruption and tend to play through hand traps better. These decks can safely out-maneuver Nibiru, the Primal Being, and they recover quicker from Infinite Impermanence and other hand traps.

The Invoked Mekk-Knight build hasn't changed much over the years, but it's now got a bigger focus on setting up Link 2 plays. Predaplant Verte Anaconda and Red-Eyes Dark Dragoon show up in just about every build you can find online, and that's for good reason. Ending on Red-Eyes Dark Dragoon when your Aleister the Invoker is negated lets you salvage your turn without compromising on your negation power.

The Mekk-Knight engine delivers a steady supply of fodder for Invocation, as well as a consistent source of rolling card advantage that can overwhelm your opponent's set-up. It's worth noting that Apollousa, Bow of the Goddess has less ATK with three materials than Mekk-Knight Purple Nightfall.

You can make this build more competitive with some Forbidden Droplet and Triple Tactics Talent, but if you're missing those cards you can opt for Super Polymerization and Dark Ruler No More instead. Evenly Matched largely replaces the need to play Forbidden Droplet, so it's a more budget-friendly pick that combos well with Mekk-Knight Purple Nightfall. You can Summon Mekk-Knight Purple Nightfall, attack with it, then use its effect to search a Mekk-Knight monster and empty your field.

Your opponent will struggle to bypass your negation effects if you can properly set up World Legacy's Secret. It's an extremely reactive card that lets you immediately respond to monster effects, which means you can play it just like you would Infinite Impermanence. However, a single copy of World Legacy's Secret turns all of your Mekk-Knights into monster-negating cards, including the column-switching Mekk-Knight Indigo Eclipse. You can lean into that by playing monsters that search World Legacy cards, and our next build showcases that exact strategy.

Pure Mekk-Knights Are Awesome Too

I'm a huge fan of the column-based gameplay that Mekk-Knights are known for, but very few hybrids make use of cards like World Legacy's Secret or World Legacy - "World Key".

Negating cards based on the positioning of your monsters is the central Mekk-Knight gimmick, and searching those cards is fairly straightforward thanks to Lib the World Key Blademaster. You can't summon Lib the World Key Blademaster without a World Legacy card in your graveyard, but luckily Girsu, the Orcust Mekk-Knight easily covers that condition by sending either World Legacy - "World Armor", World Legacy - "World Crown", or World Legacy - "World Chalice" to the graveyard.

I wouldn't recommend playing Girsu, the Orcust Mekk-Knight and Aleister the Invoker together, so this build cuts the Invoked engine for more cards that are relevant to Mekk-Knights. That means more hand traps, more Mekk-Knight monsters, and a few tech choices that make building columns a little easier.

The Extra Deck also gets a bit of an overhaul by dropping the Invoked Fusions for Mekk-Knight Links and extra copies of Lib the World Key Blademaster. You can always use Lib the World Key Blademaster to simply nab a copy of World Legacy Succession, but typically you'll want to set up with World Legacy's Secret as soon as possible.

You can actually play a few Orcust cards thanks to Girsu, the Orcust Mekk-Knight, although the only practical purpose that Galatea, the Orcust Automaton serves is to summon Dingirsu, the Orcust of the Evening Star. Still, it's worth setting aside the Extra Deck space to make room for Dingirsu, the Orcust of the Evening Star excellent removal effect. The on-theme removal for Mekk-Knights is a little tricky to set up, so I'd rather build around more generic options when possible.

Playing Red-Eyes Dark Dragoon here is a bit of a risk, but the payoff is too good to pass up. It's another option if your Lib the World Key Blademaster play is disrupted, and in a pinch you can set World Legacy's Memory to avoid a conflict with Predaplant Verte Anaconda while still summoning a Mekk-Knight on your opponent's turn. You can always chase a more combo-heavy route with Crystron Halqifibrax and Linkross, but Predaplant Verte Anaconda lets you salvage a turn when your (Girsu's](Girsu, the Orcust Mekk-Knight) negated. Meanwhile Crystron Halqifibrax, like Lib the World Key Blademaster, requires Girsu, the Orcust Mekk-Knight to resolve successfully.

Crystal Beasts Come To Help

Legendary Duelists: Ancient Millennium dropped new Crystal Beast cards about two years ago, and at the time there were a few attempts to merge Mekk-Knights with Crystal Beasts.

Personally I hadn't heard of the Crystal Mekk-Knight hybrid until earlier this summer, and it's too cool not to share! The deck's conceptually based on the idea that Crystal Beast cards can be helpful for building columns and supporting the Mekk-Knight strategy with Link and Xyz plays. Crystal Bond can search Crystal Beast Sapphire Pegasus and put another Crystal Beast in your backrow at the same time, and when Crystal Beast Sapphire Pegasus hits the field it'll add another Crystal Beast to your backrow. Building columns is insanely easy with Crystal Bond, and you can practically run six copies of it thanks to Rainbow Bridge.

So what's the rest of the Crystal Beast line-up for? Crystal Promise turns Crystal Beasts into actual monsters to use towards Link and Xyz Summons, and Crystal Conclave a searchable Compulsory Evacuation Device that can recycle Crystal Beast Sapphire Pegasus. You can actually summon Rainbow Dragon in this build, but it's mostly here for Rainbow Neos via Neos Fusion and Predaplant Verte Anaconda.

The core Crystal Beast engine has some big plays, but most of the time you'll be using it to build columns and set up Extra Deck summons. Those explosive plays are nothing to scoff at: Crystal Beast Ruby Carbuncle can summon up to four Crystal Beasts at once, and Rainbow Dragon can send every card on the field back to the deck. Rainbow Neos is a powerhouse too, trading negation for three insane removal effects.

Mekk-Knights are super affordable right now despite their excellent playability and potential. Girsu, the Orcust Mekk-Knight the most expensive card in the theme, but it's not needed in most variants when you have better Normal Summons. The Mekk-Knight engine performs best when you pair it with another tempo-centric engine: Invoked maintain tempo through the cyclical interactions between Aleister the Invoker and Invocation, and Crystal Beasts can repeatedly loop Crystal Beast Sapphire Pegasus with Crystal Conclave. There are potentially dozens more variants out there, including some–like Crystal Beast Mekk-Knights–that are totally under the radar.

Until next time then
