The Theorist, Jace Beleren has become Reality Fracture’s breakout card, at least as far as price is concerned: the base printing demands a market price of $70 on TCGPlayer. The Braintwister version has a similar price at $75 and the showcase version, exclusive to the Reality Fracture Secret Lair Bundle, goes for a staggering $134. While prices can always change, and often do, it’s hard not to remember Jace, the Mind Sculptor demanding well over $100 during its reign of terror over Standard.

It’s no surprise that The Theorist has taken a high price tag given how pushed the planeswalker is. It’s found homes in several formats, expected and surprising, primarily as a powerful control piece that generates incredible card advantage.

Commander was one of the most obvious homes for The Theorist, Jace Beleren because the card was clearly designed for it: Both the bounce ability and the stronger static ability scale with the number of players at the table, one of the easiest ways to push a card into Magic’s most popular format. If Jace survives a turn cycle, it draws three extra cards; even if it dies part way around, you probably drew at least one card, assuming combat damage does the deed.

The Theorist is such a ubiquitously powerful card that there’s no one home for it; as long as you’re in blue and run enough creatures to protect it, it’s probably a good choice for your deck. Few archetypes actively turn down a card draw engine like this. I also don’t hate it in cEDH; I can’t pretend to be an expert on the format, but decks tend to run low creature counts, so it likely sticks around for a few turns.

This price point puts Jace in a class with other hyper-powerful Commander staples like Rhystic Study and The One Ring. Though this is a notch below them (you can’t attack Rhstic Study to death, sadly), it’s good company. I’d put this in the same class as Trouble in Pairs: A draw engine good enough to be on the verge of Game Changer status, though it doesn’t exceed that threshold.

The Theorist, Jace Beleren has also affected Standard, though it’s not nearly at the peaks of the Mind Sculptor. Jace primarily shows up in Azorius () and Dimir () control variants to provide a mixture of card advantage and a win condition with its Illusion token creation. It’s worth noting that the two decks are markedly different, though they fall under the control umbrella.

The Azorius control deck (which showed up in the Top 16 of a recent MTGO Challenge, piloted by AvianScrolls) takes the traditional control route: Lots of cheap countermagic and removal plus decent card advantage to grind your opponent into the dirt; it wins by stopping them from winning. Other notable pickups from Reality Fracture include Jace's Machinations as a draw spell and Countersculpt as a cheap counterspell to go with all those Jaces.

The Dimir control deck—which took the top four of that same challenge, in the hands of gazmon48—only runs two copies of The Theorist because it takes a different route. It includes the Superior Spider-Man package from before FRA hit standard. The deck picked up serious support from this set; in addition to Jace as a draw engine, it got a discard outlet in Seasoned Cryomancer, a new “reanimation” target in Uldaros Theorix, and Theorix Charm as an all-around handy spell. Around that package are the traditional elements of a control deck.

Though The Theorist hasn’t had as large an impact on other formats as Commander and Standard, it sees some amount of play in other formats.

A Dimir control deck did well in a Pioneer Challenge this past weekend, piloted by Tinker147. The deck runs the same Superior Spider-Man package as the Standard deck but gets a major upgrade in the interaction department in Fatal Push and Thoughtseize.

It also sees Modern play, typically as a one-of in Scepter-Chant decks, the currently popular control deck built around the combo of Isochron Scepter and Orim's Chant that locks your opponents out of casting spells and attacking.
