It was a weird week in the secondary market.

Friday's reveal of the set list for Battles of Legend: Armageddon made a big impact on the TCGplayer Marketplace, with the reveal of Invocation being particularly influential, while the impending release of Rise of the Duelist also lit a fire under some hot prospects. And yes. That WAS an Infernoble joke, foreshadowing the first card in our Top 10 countdown. Two Infernoble jokes, actually, but who's counting.

Competitive picks from Toon Chaos were still big picks too, but the real surprise this week was a sudden surge of demand for Dinosaur cards. Dinosaurs haven't won anything of note recently, and as far as I'm aware there aren't any big reprints or new releases that hit public awareness this week. And yet, almost half the Top 10 was Dinosaur cards. They all followed a particular pattern too, more on that in a bit.

For now, buckle up and let's get right into it. The following were the Top 10 best-selling cards on TCGplayer this week, from the weekend to today.

#10 Sublimation Knight

Rise of the Duelist is just a couple of weeks away with an August 7th release date, heralding the arrival of the full Infernoble Knight theme. With Infernoble Knight - Roland at $3 a copy and Infernoble Knight - Renaud still pushing 20 bucks, Sublimation Knight's a steal by comparison at 75 cents, searching your deck to set up your graveyard – huge with the new Infernobles coming in ROTD.

#9 Chaos Valkyria

Chaos Valkyria: still super competitive and still super cheap. Chaos Valkyria the second most expensive Super Rare from Toon Chaos, but that's not saying much: due to set composition Chaos Valkyria Market Price is still just over a buck. Toon Harpie Lady occupies a similar price range, Chaos Space is still around 4 dollars, and the remaining 12 Supers in the release are 75 cents or less.

Meanwhile Chaos Valkyria (CR) is still largely maintaining its 80 to 90 dollar value, though we are seeing a few deals – at least two copies inexplicably sold for less than $50 this week, so keep an eye out for deals. Even though Toon Chaos is getting a reissue in a few weeks, those cards will almost certainly be Unlimited editions and 1st Ed Collector's Rares probably won't drop much if at all in the long term.

#8 Salamangreat Almiraj

As soon as it was revealed that Invocation was getting a reprint in Battles of Legend: Armageddon, demand for Salamangreat Almiraj spiked accordingly; for the uninitiated, Salamangreat Almiraj sees play with Aleister the Invoker and pals to help establish Fusion Material of different attributes. Surprisingly Salamangreat Almiraj price didn't follow the demand trend, dropping from $1.50 to $1.00 week over week.

#7 Darkest Diabolos, Lord of the Lair

The Structure Deck: Sacred Beasts release was a big hit over the weekend, and Darkest Diabolos, Lord of the Lair emerged as one of the best tech cards for the strategy. Dark Summoning Beast, Chaos Summoning Beast and Raviel, Lord of Phantasms all tribute one of your monsters, so they can trigger Darkest Diabolos, Lord of the Lair in the graveyard and return it to the field. From there it's a 3000 ATK beater and its effect can pluck a card out of your opponent's hand; impressive once, but even better if you're doing it turn after turn.

Darkest Diabolos, Lord of the Lair almost doubled in price since last week, rising from an average sale value of $2.10 to more than $3.80.

#6 Overtex Qoatlus

And here's where stuff gets weird. Dinosaurs are always massively popular in Yu-Gi-Oh; whether the deck's a fringe rogue strategy or a top competitor, Dinos are always solid sellers and they draw a lot of attention for creators like yours truly. But this week demand for the cards absolutely exploded with a huge number of unique purchases; that means we're looking at the sheer number of individual orders being made, helping us filter out the speculators and see real tournament interest.

With Dinosmasher's Fury reprinted a few months ago, the big sellers this week were all competitive cards not available in the Structure Deck. What popularized Dinosaurs all of a sudden is a mystery, but four of top 6 cards for the week were staple Dinos for competitive builds. On that note…

#5 Giant Rex

Giant Rex also made the cut, which is no surprise since it's still only been printed once, in Battles of Legend: Light's Revenge. This is a frequent singleton in Dinosaur decks, repeatedly returning to the field in combination with cards like Ultimate Conductor Tyranno and Double Evolution Pill, and two things make it impressive as a Number 5 entry: the fact that it's not cheap at 7 to 8 bucks, and the fact that you'd only ever play one copy. Sure enough, literally no buyer this week picked up more than one, showing absolute player interest with zero speculation.

This card's up a buck from where it was last week, but supply's still pretty deep in the Marketplace.

#4 Evolzar Dolkka

Another Dinosaur staple that's lacking reprints, Evolzar Dolkka first appeared in Photon Shockwave and was only reissued once, in the 2012 Collector's Tins. Now even the Tin version is $15 and up. This is a must-play at one, though it's common to see players running two copies, and again, the numbers people were buying them in suggested only player interest, with no real chance at speculation – unsurprising for such an expensive card.

I always forget how badly Evolzar Dolkka needs a reprint, and every time it pops up, I'm shocked that it's been nearly a decade since it was in a retail product. At this point the interest in Dinosaurs is so consistent, I feel like Konami could just put all the non-Structure cards into a reprint set and move a ton of it. Maybe we'll see it happen in Maximum Gold?

Here's hoping.

#3 Number S0: Utopic ZEXAL

Numerons are going to demand respect once they arrive in Battles of Legend: Armageddon next week, offering easy access to Number S0: Utopic ZEXAL and effectively stealing entire turns from your opponent with its effect. Hanko discussed the impact of the Numerons and their use in Zexal locks just a few days ago, and Sam showed you a build he was using live and in action . The market responded accordingly, with Number S0: Utopic ZEXAL doubling in price over the last several days.

If you have any shred of hope that players are going to ignore ZEXAL Numeron strategies, here's your clear market indicator that they're going to be seeing play.

#2 Animadorned Archosaur

The final Dinosaur card in the Top 10, Animadorned Archosaur's 30 dollar price tag did nothing to deter player demand, landing it at Number 2 for the week in unique purchases. Searchable with Miscellaneousaurus, Archosaur's become a must at 3 copies per deck in modern Dinosaur builds, popping Babycerasaurus and Petiteranodon while fetching you Double Evolution Pill in the process. A simple play starting with Animadorned Archosaur and a baby Dino can turn into fields like Evolzar Dolkka, Ultimate Conductor Tyranno and Simorgh, Bird of Sovereignty Special Summoning Barrier Statue of the Stormwinds. Not too shabby.

And spoiler: with Overtex Qoatlus at Number 6 and Animadorned Archosaur at Number 2, Double Evolution Pill almost made the Top 10 this week, coming in just shy of the cut at Number 11.

#1 Chaos Space

And finally, Chaos Space remains the best-selling card from Toon Chaos, and the best-selling Yu-Gi-Oh card on TCGplayer for another week. Chaos Space is clearly a perennially useful combo card and it didn't take long for players to identify it as a topnotch addition to Dragon Link decks. It's becoming especially notorious in the FTK build with Black Garden and Earthbound Immortal Aslla Piscu, which is starting to see some legitimate player interest online.

Gimmicks aside though, Chaos Space is an incredible card for the sheer economy it offers, and the fact that it can let a Dragon Link player combo off without using their Normal Summon. That makes the deck a lot more flexible than it was before, which is saying something because Dragon Link already had tremendous range.

With Double Evolution Pill at Number 11, Nibiru, the Primal Being appeared at Number 12 and Xyz Encore powered surged to Number 13 under pain of Numeron shenanigans. Danger!? Jackalope? took the Number 14 spot, while Parallel eXceed came in at Number 15. Note that despite being a huge hit out of the gates when Legendary Duelists: Season 1 dropped, Millennium-Eyes Restrict plummeted like a rock this week, dropping to Number 20 on the best seller charts.
