The first Regional weekend of the new Advanced Format is over, and so isthe Ultimate Duelist Series Invitational! Now, we have our first look atthe highest-selling cards of the new era of competition, as players reactto news about the most successful strategies.

The Top 8 of the Ultimate Duelist Series consisted of Trickstars,ABC-Dragon Buster, and True Dracos with one seat each, and then a whoppingfive duelists playing Pendulum Magicians… including eventual winner, ournew Ultimate Duelist Jeff Jones! That kicked off huge demand for PendulumMagicians on Sunday, but a TON of other decks topped Regionals as well, andthose strategies had some influence in the TCGplayer Marketplace too.

On top of that, no fewer than three of the four promo cards from theCode of the Duelist: Special Edition release made the Top 10. Youcan probably guess which card didn't make it, but spoiler: it was CyberseBeacon.

The first hit of the weekend was one of those very promos, so let's diveright into the countdown with the tenth highest-selling card across theTCGplayer Marketplace, from Friday to Monday morning.

#10: Skull Meister

The long-maligned, occasional Top Cut-making hand trap saw an uptick inpopularity after some recent tournament success, and aSpecial Edition reprint that took it from 20+ dollars to about abuck-fifty. With an effect that actually makes it comparable or better thanAsh Blossom & Joyous Spring in some matchups, Skull Meister could proveto be relevant as competition moves forward.

We've already seen it topping Regionals this past weekend, so it'sdefinitely something to keep in the back of your mind.

#9: Double Iris Magician

The next five cards in the Top 10 are all here because of PendulumMagicians. The tale of the Top 8 at the UDS in Kissimee Florida got aroundfast, and Pendulum Magician lists that topped Regionals are still tricklingin. Keep an eye on theDeck Archivein the next day or two as we continue to add more decks from the weekend.

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

#8: Astrograph Sorcerer

While Astrograph Sorcerer was an optional card that wasn't always played inTop Cut Pendulum Magicians in the past, it's now emerging as a must-run,thanks in large part to its interaction with Wavering Eyes. Destroying twoor more Pendulums with Wavering lets your search Astrograph Sorcerer, whilealso providing the destruction needed to Special Summon it and trigger itsown search effect. Hayden Makertalked about that play coming off his Top 8 in St. Louis.

Two free searches and a free beatstick is pretty good when it's rolled intothe activation of what may be the best card in the game, not to mention allthe other uses for Astrograph.

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

#7: Harmonizing Magician

A crazy Level 4 Tuner in a strategy that only seems to have become evenmore focused on Synchro Summons, Harmonizing Magician is the gateway to awealth of Synchro Monsters, the most mundane being PSY-Framelord Omega andIgnister Prominence, the Blasting Dracoslayer. From there it just getscrazier, with monsters like Beelze of the Diabolic Dragons, EnlightmentPaladin, and Supreme King Dragon Clear Wing in the mix.

The Pendulum Magician deck powers out some amazing Synchros, almostentirely thanks to Harmonizing Magician, and often fields them for a singlecard. Crazy stuff.

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

#6: Purple Poison Magician

The deck's go-to low Scale is an obvious three-of, and it soldappropriately over the weekend. It's tough to imagine not running a fullplayset.

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

#5: Wavering Eyes

And finally, the card that's making it all happen: Wavering Eyes was downfrom the Number 1 spot last week, but still hung tight at Number 5 afteraccomplishing some frightening and not-at-all unpredictable things at theUDS Invitational. This is a format-shaping card, and a must-own as both acurrent play, and a potential counter if competition comes to that point.

#####CARDID= 18642#####

#4: Proxy Dragon

Proxy Dragon was trading off against Pot of Desires as the Number 1 andNumber 2 bestselling cards for weeks after both appeared in the2017 Mega-Tins

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

#3: Pot of Desires

…And both cards have remained wildly popular even through the formatchange.

Again, with the first weekend of competition offering a huge, wide openfield of deck choices, generic splashable cards like Proxy Dragon and Potof Desires are some of the most attractive cards in the game. There arevery few decks that don't want to play Pot of Desires these days.

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

#2: Mistar Boy

But Mistar Boy outsold them both! Seemingly custom-made for PaleozoicFrogs,we already saw Mistar Boy carry at least one player to a Top 8 finishin Regional Qualifiers. With Rescue Rabbit back at three-per-deck Mistar Boy's just too good; aMissus Radiant for Water decks that lets you reuse cards like SpellbookMagician of Prophecy.

Mistar Boy does ridiculous stuff right now, and with that top hat andmonocle, it looks good doing it.

#1: Solemn Strike

Finally, the bestselling card of the weekend is no surprise whatsoever, asthe Code of the Duelist: Special Edition reprint brought SolemnStrike from nearly twenty dollars to seven. That's still an insanely highprice point for a Special Edition reprint, but a lot of top decks from theweekend are running more traps than we usually saw last format, and SolemnStrike appears to be the most popular.

With an MSRP of $9.99, Code of the Duelist: Special Editions areactually selling for twelve dollars and up here at TCGplayer. The massivedemand for Solemn Strike is one of the biggest reasons that's happening,and it might not slow down any time soon.

#####CARDID= 20556#####

What else was hot? The Spellbook draw engine of Spellbook Magician ofProphecy, Spellbook of Secrets, and Spellbook of Knowledge finally startedseeing serious play this weekend, and that drove Knowledge to the Number 11spot.

Black Fang Magician and Time Pendulumgraph took Number 12 and Number 13,showing that the enthusiasm for Pendulum Magicians runs deep, while MissusRadiant and Denko Sekka rounded out the Top 15.

Pendulum Magicians are definitely the story of the weekend in the TCGplayerMarketplace so far, but the interest inCode of the Duelist: Special Edition is almost unique, while wehave some strong market indicators showing that a lot of players areconsidering Paleozoic Frogs and the Spellbook draw engine. Watch for all ofthose trends at your locals.
