Our latest Monday Market Watch saw a massive swerve, as buyers reacted tothe reveal of the four new F.A. cards in Extreme Force.

Four days later, most of that momentum has disappeared now that hundreds ofcopies of existing F.A. cards have been sold – most of them to buyersordering just a playset, suggesting they're actual players looking to runthe theme when EXFO hits shelves. Those sales died down over the course ofthe week, though one big card for the theme remained in high demand, afterroughly tripling in price.

Beyond that it was another big week for Pendulum Magicians, as theyreturned to fill the gap left by the retreating F.A. cards. Not only were anumber of consistent performers big from the theme, one of the deck'sbiggest all-stars is finally on a long-awaited upward Price Trend, whichdrove massive demand this week.

From there we saw a repeat performance from an offbeat hit a week ago, aswell as driving demand for two of the format's biggest staples. Let's getright into it, and look at the Top 10 bestselling cards in the TCGplayerMarketplace this week, from Monday to Friday!

#10: Performapal Pendulum Sorcerer

Once played as a singleton in Pendulum Magicians, Performapal PendulumSorcerer's become a two-of in almost every build and has even startedseeing use in triplicate. Both the Breakers of Shadow original andthe CT13 Super Rare are now on rising Price Trends, with both cards onfewer than two pages of stock in the Marketplace.

#9: Black Fang Magician

On the other hand, Black Fang Magician was on a slight downward Price Trendthis weeks, slipping to an average Market Price of about 60 cents. Italways makes more sense when other, more important Magician cards run asthree-ofs outsell Black Fang Magician, since players often run just twocopies.

#####CARDID= 21796#####

#8: Harmonizing Magician

Harmonizing Magician saw a similar level of action, beating out Black FangMagician by just a few copies for the week with a similar number of orders.Again, that makes the demand for Black Fang a little surprising givenHarmonizing Magician's status as a must-run at three.

#####CARDID= 21802#####

#7: Marshalling Field

Meanwhile Marshalling Field just kept on selling like hotcakes, even asdemand for other F.A. cards died down. Unlike the F.A. name-stampedcommons, Marshalling Field is a foil card from a relatively scarce specialbooster release, and that meant lower supply as well as a strong imperativedriving players to get their copies now, before a potential price spike.

That spike happened this week, as Marshalling Field roughly tripled invalue. And while that only meant a three dollar price tag, there were fewerthan 60 copies left on TCGplayer as of this writing, half of which wascontrolled by a single vendor. Whether more copies will come out of thewoodwork to replace copies sold before the price can rise even higher is upin the air, but with hundreds of sales the past week, we might find out theanswer to that question in the next few days.

#####CARDID= 18123#####

#6: Oracle of Zefra

The key Field Spell for Zefras saw enough sales to raise some suspicions ofat least minor speculation this week, as Zefras continued to do exceedinglywell in OCG tournaments overseas. While the use of Oracle for Set Rotationhas died down stateside, it's a three-of for actual Zefra decks, and acouple near-miss showings in recent TCG tournaments have helped to bridgethe link between the successful OCG builds and the market here in NorthAmerica.

Both the reprint and the original are still in neutral price territory forthe moment, but it's unclear if demand will rise, or fall off through theweekend.

#####CARDID= 21842#####

#5: Purple Poison Magician

You can't Pendulum Magician very hard without Purple Poison Magician, butlike Black Fang Magician, it's riding a slight downward price trend.Regardless, sales for Pendulum Magicians are up roughly 40% from where theywere in early December, including Purple Poison.

#####CARDID= 21798#####

#4: Double Iris Magician

Meanwhile nearly at the top of the heap for Pendulums, Double Iris Magicianremains one of the deck's strongest sellers. Searching the deck's keyContinuous cards, it's a massively important play starter that getseverything else rolling, while creating win scenarios with its damage buff.It's one of the most flexible cards in the Pendulum Magician arsenal, andit's never a surprise to see it this high in the Top 10.

#####CARDID= 21795#####

#3: Pot of Desires

For almost the first time ever, Pot of Desires actually took a backseat to…

#####CARDID= 22118#####

#2: Proxy Dragon

…Proxy Dragon! Demand for Proxy Dragon is actually substantially down thismonth from where it was in December, but that didn't stop it from being theNumber 2 bestselling card in the Marketplace this week. Still available forless than a buck, Proxy's a must-own that's become ubiquitous in almost allstrategies. If you're playing competitive Yu-Gi-Oh, you need to have ProxyDragon or your options are severely limited. The sustained demand for acard most players only run one copy of continues to speak well for theinflux of new players taking up competitive dueling.

#####CARDID= 22117#####

#1: Astrograph Sorcerer

And finally, Astrograph Sorcerer sold like hotcakes this week. Finallyhitting an upward Price Trend, its average Market Price the past few dayswas $3.78 as of this writing and available copies are starting at $4 andup. There are just over 300 copies left in the TCGplayer Marketplace, andwith sales the way they were this past week that could mean a potentialbuyout in a matter of days.

If that happens, we could easily see Astrograph Sorcerer settle at the sixdollar mark given the price of current stock. Will demand for AstrographSorcerer hold out under the pressure of rising prices? Will that potentialfor growth create more speculation, or spur more players onward to buytheir playsets? We'll have to wait and see.

#####CARDID= 21793#####

Beyond the Top 10, the bestselling cards from Number 11 to Number 15 wereall Pendulum Magician cards: Wavering Eyes, Time Pendulumgraph, DuelistAlliance, Star Pendulumgraph, and Supreme King Gate Zero.

The giant push we saw for Chronograph Sorcerer last week dropped off almostcompletely, but Magicians continue to be the hottest point of interest inthe secondary market. With recent tournament results in the TCG showingstability for the theme, huge successes in the OCG – especially for newvariants, and Extreme Force just around the corner with themuch-awaited Heavymetalfoes Electrumite, there are a lot of strong pushfactors keeping Magicians moving.

Join us on Monday to see where the action is headed, in our next MarketWatch.
