Each booster box contains 24 packs of 9 random cards per pack.
The King is not amused…but he will be – and you will, too! – with the brand-new “Evil HERO” monsters coming in Supreme Darkness!


Supreme King Jaden’s “Evil HERO” monsters are back in a big way! Evil versions of Elemental HEROes Bubbleman and Prisma are coming, and the Supreme King’s new version of Neos, which has the power to take over your opponent’s monsters! There are plenty of “Evil HERO” Fusion Monsters to choose from, and this set adds even more, plus new support cards to make it easier than ever.


If you’re looking for something in the fast lane, it’s time to speed back into action with new “Speedroid” cards that make Synchro Summoning a breeze! There are two new Pendulum/Tuner Speedroid monsters, plus a couple of new Synchro Monsters styled after Yugo’s favorites, including the biggest “Clear Wing” Synchro Dragon yet. Put the pedal to the metal and leave your opponents in the dust!


Fans of Synchro Summoning can also grab new “Crystron” monsters, including a new Synchro Monster. Keep an eye out for a new Level 2 Tuner that can Special Summon a “Crystron” anytime your opponent activates an effect, then you can immediately perform a Synchro Summon!
And an all-new theme that are the masters of bouncing around the field makes its grand debut in Supreme Darkness. This Deck works by placing its Continuous Trap Monsters straight into your Spell and Trap Zone. As face-up Continuous Traps, they give constant buffs to all your Warrior monsters. But when you want, these Trap Cards can spring to life as Warrior monsters themselves, then bounce back to the safety of the Spell and Trap Zone when things get too hectic, ready to pop out again when the time is right.
You can look forward to all of this and so much more that is yet to emerge from the Supreme Darkness!


Supreme Darkness has 101 new cards in total, including a brand-new World Premiere theme that you won’t want to miss. It also continues the 25th Anniversary Celebration by including 25 Quarter Century Secret Rares, including 1 special card!

Great Product
Size: 90 Count (Pack of 1)
Life Extension’s Neuro-Mag Magnesium L-Threonate is a standout supplement designed to support cognitive health, and after trying it for several months, I can see why it’s so highly regarded. This product contains magnesium L-threonate, a unique form of magnesium that’s specifically formulated to cross the blood-brain barrier, making it highly effective for brain health. Each serving (three vegetarian capsules or one scoop of the tropical punch powder) delivers 2,000 mg of magnesium L-threonate, providing 144 mg of elemental magnesium. Here’s my take on its performance, benefits, and overall experience. Pros: • Cognitive Support: I noticed improved mental clarity and focus after about two weeks of consistent use. Tasks that require working memory, like recalling details or multitasking, felt smoother and less taxing. This aligns with research indicating magnesium L-threonate’s ability to enhance synaptic density and cognitive function, particularly in aging individuals. • Sleep Benefits: While not marketed primarily for sleep, I found that taking it about an hour before bed helped me fall asleep faster and wake up feeling refreshed. This echoes user experiences shared on platforms like X, where some reported better sleep quality and daytime alertness. • High Absorption: Unlike other magnesium forms like oxide or citrate, which are better for whole-body benefits, magnesium L-threonate is designed for brain absorption. Studies cited by Life Extension show it can boost magnesium levels in cerebrospinal fluid by 15% in animal models, which likely contributes to its cognitive effects. • Clean Formula: The capsules are gluten-free, non-GMO, and vegetarian, with no major allergens or unnecessary fillers. The powder version has a pleasant tropical punch flavor, making it easy to mix with water or juice. • Trusted Brand: Life Extension’s rigorous testing for purity and potency gives confidence in the product’s quality. Their transparency, including offering Certificates of Analysis, is reassuring. Cons: • Price Point: Neuro-Mag is pricier than standard magnesium supplements, which might be a drawback for budget-conscious buyers. However, the specialized form and targeted benefits justify the cost for those prioritizing brain health. • Time to Notice Effects: While some users report benefits in as little as six weeks, full effects may take up to 12 weeks, requiring patience. Final Verdict: Life Extension’s Neuro-Mag Magnesium L-Threonate is a high-quality supplement that delivers on its promise of supporting cognitive health. Its ability to enhance memory, focus, and even sleep quality makes it a worthwhile investment for those prioritizing brain function. Great benefits and clean formulation make it a top choice!

Size: 90 Count (Pack of 1), Size: 90 Count (Pack of 1)
This magnesium L‑threonate supplement has been a great addition to my daily routine. The capsules are easy to take, gentle on my stomach, and I’ve noticed a clearer, more focused feeling throughout the day. It also brings a nice sense of calm in the evenings without making me groggy. The formula feels clean and well made, and it fits effortlessly into a wellness routine. If you’re looking for a reliable magnesium option that supports relaxation and mental clarity, this one is a solid choice.

Highly recommend for sleep, mood, mental health
Size: 90 Count (Pack of 1)
I recently re-discovered this supplement, and I'm buying extras left and right and recommending to everyone I talk to. I've been working on increasing my HRV and supporting my nervous system, and the L-threonate is a rockstar for that. I was taking glycinate for a few months, and I found an old bottle of this one and added just 2 capsules, and the effect on my sleep was immediate. Way better than melatonin. My Fitbit is tracking much lower restlessness and more deep sleep, and I actually wake up feeling refreshed ?? and before my alarm, even! I'm noticing lower anxiety and an overall better mood, and it's only been 4 days. This bottle definitely holds its value, and the price is good, especially if I can get these benefits with just the 2 caps and not 3.

Big winner for helping BETTER SLEEP
Size: 90 Count (Pack of 1)
Life Extension is top of the line on most things they have. also pricier than most, but I buy three items for them regularly for many years. This Neuro-Mag with L-Threonate is excellent for boosting better sleep. This is a newer addition to their line. I also suggest trying their Mult-B complex and their B-12 elite (sublingual) On nearly all items, their quality control is near THE TOP of all suppliers. They also have supported vitamin and supplement research on my items over the last 40 years
