Welcome to the first Market Watch update in the wake of YCS Niagara!

The YCS weekend was a breakout event for Thunder Dragons and Dangers;Thunder Dragons immediately became one of the most competitive decks of theformat, while Danger monsters topped inGoukis,Burning Abyss, and thecontroversial Firewall FTK deck.

Coming off the release of Soul Fusion on Friday, the initialmarket reaction was what we'd expect: a ton of enthusiasm largely for SuperRare, Rare, and Common cards that were in big supply and thus hugelyaffordable, making them easy to pick up alongside bigger purchases. But asthe week wore on that trend started to ease into clear market responses towhat we saw at YCS Niagara, leaving us with a Top 10 of casual pickssplashed with a healthy dose of tournament-trending cards.

If this is your first Market Watch with us here at TCGplayer, it'simportant to know that our countdown's ordered by sheer volume of cardssold: that means we don't cherry pick the numbers by price or rarity, andthat in turn lets us see trends that are invisible otherwise. When playerspick up thousands of copies of a key common for a new deck that canindicate a mass migration of tournament players, but you might not spotthat trend if you were only looking for price spikes in big cards. Andsince we're a gateway to more than 1,000 active Yu-Gi-Oh! sellers we seeall the action.

With all that in mind, let's get into the Top 10 this week, from Monday toFriday.

#10: Danger! Mothman!

The Danger monsters were huge in all sorts of different strategies at YCSNiagara, with Danger!? Tsuchinoko? popping up everywhere and bringing cardslike Danger! Nessie! and Danger!? Jackalope? with it. But Danger! Mothman!was largely playedin just the FTK builds, so keep that in mind when gauging Mothman as the bestselling Danger cardof the week. The current Advanced Format won't change until after YCSPasadena, so get ready to see Firewall FTK in Regionals and locals rightthrough most of November.

Hide your lamps.

#9: D/D/D Flame High King Genghis

As much as Different Dimension Demons may have never quite gotten off theground in the TCG, the theme's still got a strong fanbase and new D/D andD/D/D cards are always popular. Combine that with the fact that D/D/D FlameHigh King Genghis is legitimately impressive and you've got a recipe forpretty predictable demand: with a free Special Summoning effect and atopnotch negation ability combined with a very solid 2800 ATK, it's a verysolid monster for a fan-favorite strategy. I don't think D/D/Ds are readyto reprise their limited run in Regionals, but at 5 cents a pop, this wasan easy pick for a lot of players.

#####CARDID=24447#####

#8: Clock Wyvern

A mix of plot power, Link potential, and Cyberse synergy, Clock Wyvern'sanother affordable pick that melds fanservice with competitive merit. An1800 ATK beater that can split itself to make an instant Link Summon isgoing to be solid no matter what way you cut it, even if we're stillwaiting for the final components of its home strategy. Now's a great timeto get it, since it could have the potential to see some growth along thelines of a card like D/D Savant Thomas and other marquee regular Raresbefore it.

#####CARDID=24351#####

#7: Extra-Foolish Burial

Speaking of potential, Extra-Foolish Burial's a combo-driven utility cardthat just does a lot of stuff that would be impossible otherwise. I thinkthe big, easiest options here are Herald of the Arc Light and Elder EntityN'tss, for search power and instant destruction respectively, but thedeeper down the rabbit hole you go the more potential there could be forcraziness in the future.

Anything like this card gets more powerful with every release, andeventually they can even become problematic, so Extra-Foolish Burial'sdefinitely a card to keep an eye on.

#####CARDID=24417#####

#6: Impcantation Penciplume

Impcantation Talismandra and Impcantation Candoll were two of the mostpopular cards in Cybernetic Horizon, arriving in a similartimeframe as the new Blue-Eyes White Dragon Ritual support and quicklyreaching a solid price on the secondary market. Those cards are still abuck a piece, which is significant considering that they've probably neverappeared in a Top Cut above locals.

Flash forward to now, and both of the new Impcantation cards made the Top10 this week. While Talismandra and Candoll searched cards from your deck,Impcantation Penciplume triggers in the same way but retrieves a RitualMonster from your graveyard, giving Ritual decks a longevity option. At thesame time they offer more chances to Special Summon those frankly betterImpcantations from your deck in the first place, and Penciplume's even auseful Level 3. Not bad.

#####CARDID=24373#####

#5: Frightfur Patchwork

Frightfur Patchwork was the Number 3 bestselling card over the weekend, butdemand slowed a little bit as the week wore on. Patchwork's been one of themost-wanted cards here in the TCG ever since it debuted two years ago inthe OCG, and while its power level has slid over that time, it stillpresents pretty easy OTK options along with flexible search power andawesome card economy. While Fluffals may never become a true threat, Isincerely think someone will top a Regional with them some time thisseason.

#####CARDID=24451#####

#4: Impcantation Bookstone

Back on the Impcantation side, Impcantation Bookstone's the book-end forPenciplume, working in the same way but retrieving a Ritual Spell insteadof a Ritual Monster. Again, it's largely worth playing in a Ritual deck tobring out the better Impcantations, which isn't a sleight against it; thosecards are good when they go off, and now they're more consistent.

Do they make Ritual Monsters competitive? Probably not. But Rituals remaintremendously compelling and fun, and any time good Ritual support arrivesthere are going to be droves of people clamoring to pick those cards up.Rituals are a big part of the original Yu-Gi-Oh! series, and that's keptthem in the zeitgeist for the better part of two decades.

#####CARDID=24374#####

#3: Herald of the Abyss

Herald of the Abyss is a flexible removal card that can dodge non-targetingand non-destructible clauses on big boss monsters, shredding cards thatnormal removal spells can't touch in return for a mid-sized Life Point costand an element of choice that may or may not be relevant depending onmatch-up.

When Herald sold well over the YCS weekend its future seemed a bit shaky;it was absolutely nowhere at YCS Niagara, since there are very few cardsprotecting themselves from destruction or targeting right now – a far cryfrom where we were around this time last year. But Herald sold incrediblywell throughout the entire week, as players seem to be hedging their betsabout future threats.

And that's not unwise. There are lots of eras of competition where thiscard would've been huge, and we're sure to see formats like that sometimein the future. At 50 cents each, it's a solid pickup.

#####CARDID=24415#####

#2: Metaion, the Timelord

With four different printings including an attractive Ultra Rare that'savailable for around 60 cents, Metaion, the Timelord was huge as soon as wesaw that the Thunder Dragon threat was real. While Book of Eclipse sawnearly equal use to counter Thunder Dragons at YCS Niagara, Metaion offersa more thorough answer so long as you're going second, blowing away bigfields packed with copies of Thunder Dragon Colossus and Thunder DragonTitan.

Whether you play Book of Eclipse, Metaion, the Timelord, or both, you needsome sort of sided answer to Thunder Dragons. Metaion's the clear winner interms of copies sold, and that's very actional information for tournamentcompetitors.

#####CARDID= 23560#####

#1: Dinowrestler Pankratops

And finally, the card that's often called "The Best Card In Soul Fusion" bycertain camps of competitors moved huge numbers as soon as Friday hit, andhasn't stopped since. After seeing considerable Side Decked use at YCSNiagara, Pankratops is a $1.25 common that's easily considered for SideDeck slots in almost any strategy this format. It's raw power, it's a bodyon board and it's an answer to whatever ails you.

Whenever a card is this flexible and so budget, demand is always going tobe huge, so watch out for it in your tournaments.

#####CARDID=24359#####

That's it for today, but we'll be back again next week with another look atthe TCGplayer Marketplace as more trends develop. It's going to be aninteresting four weeks as we count down the days to YCS Pasadena and thesecond showing of Firewall OTK, so I'm expecting to see some interestineevidence of trends here in Market Watch.

We'll see you then!
