MTG Weekly Price Spikes: 10/10 – 10/16

Two weeks after Reality Fracture released, the latest MTG set still has the Magic card market firmly in its grip.

Sphinx Season refuses to end, one of the set’s new commanders is already putting up cEDH results, and an old Wilds of Eldraine combo piece has found yet another way to go infinite.

Let’s check this week’s biggest movers!

The Theorist, Jace Beleren

For the huge majority of new Magic cards, release day is when reality catches up with preorder prices: Supply hits the market, pre-release hype cools down, and even great new cards frequently get cheaper.

But it looks like The Theorist, Jace Beleren has decided to rewrite that part of reality. The regular version was trading just above $40 last Friday, and is well past $60 today, after briefly touching $70 before cooling down a little.

There’s a pretty convincing reason why: players have now had two weeks to discover that The Theorist, Jace Beleren is really, really good. It’s hands down one of the most popular Reality Fracture cards in casual Commander decks. And as Andy reported yesterday, The Theorist, Jace Beleren has quickly become a real Standard card, particularly in Azorius and Dimir Control, while it also started showing up in Pioneer Dimir Control and even as a one-of in Modern Scepter-Chant lists.

Radiant Solar

Radiant Solar has roughly doubled since last week, from about $2-$3 to around $4-$5, and it breaks a bit with the trends we’ve seen for most cards in the last few weeks (namely planeswalkers and sphinxes; more about those in a bit!): This spike seems to be above all about cEDH.

The culprit here is Dack Fayden, Helping Hand, one of the stranger commanders from Reality Fracture. Dack’s enter-the-battlefield trigger reveals cards until you find a creature for each opponent, first puts those creatures onto the battlefield under your control, and then gives one to each opponent.

That sounds like a drawback… but as Andy reported, here’s where Radiant Solar comes in.

The card ventures into the dungeon whenever it or another nontoken creature enters under your control. And Dack’s creatures do enter under your control first, so you get those triggers before your opponents ultimately receive the creatures. 

Writing for EDHREC, Harvey McGuinness calls Dack a “one-spell boogeyman” and shows how Dack lists can make the commander’s ETB deterministic: resolve Dack with the proper creature package and the deck can assemble a winning loop regardless of which relevant creatures appear first.

And, crucially, we’re past theorycrafting: Recent Dack lists packing Radiant Solar are already getting good results in cEDH tournaments. Coupled with the fact that it has never been reprinted and the original is from a somewhat old set, and you’ve got all the ingredients for a card’s price to explode.

Magister Sphinx

Sphinx Season isn’t over, it seems. And our Spikin’ Sphinx of the Week this Friday is… Magister Sphinx.

Again!

We covered this card last Friday after the Double Masters 2022 printing more than doubled in a week, and it turns out it wasn’t finished: It has soared even higher, and is trading at almost $4 now.

And, yeah, it’s all about Your Eminence, The Ur-Sphinx…

… which keeps spiking every sphinx in sight.

Agatha of the Vile Cauldron

Last but not least, though, Agatha of the Vile Cauldron is here to prove that Reality Fracture doesn’t need sphinxes or planeswalkers to make old cards more expensive: Agatha has roughly tripled in price since October started, and has been climbing sharply since last week:

Agatha already sees a bit of cEDH play with Kenrith, the Returned King. But now she’s getting demand from two new commanders, and specially from Aerid Konstrari.

Agatha of the Vile Cauldron reduces the activation costs of creatures you control by an amount equal to Agatha’s power, although she can never reduce one below one mana. Get Agatha to five power, and you get an infinite combo with Aerid Konstrari!

Aerid’s activated ability normally costs six mana. With a five-power Agatha, it costs only . Activating it creates a Heartwood token, which can immediately tap for red or green mana, which is enough to pay for the next activation. Repeat as necessary for infinite Heartwood tokens; add something like Doubling Season for making infinite red or green mana. 

Agatha also goes crazy with Kiora of Fire and Ashes. If Agatha reaches seven power, she can reduce Kiora’s token-making ability to just one mana. Add Ganax, Astral Hunter, and each Dragon Kiora creates also makes a Treasure, which pays for the next activation.
