Pencils down, brewers. The next Magic: The Gathering Banned & Restricted update lands today, Monday, May 18, and it has been hanging over every Pioneer 5–0 list and Standard sideboard guide for weeks. This is the longest gap between expansions on the 2026 calendar, which means Wizards has more clean signal than they’ve had in months — and players have more on the line than usual heading into a Monday morning.
Here at Mana Riot Games we’ve been watching the data, the chatter, and our own counters move at the shop. Below is the short version of what we’re actually expecting — format by format — plus the cards that should be holding their breath.
Why This B&R Update Is Different
Wizards changed the cadence this year, opening multiple intervention windows instead of one annual reset. The February and March 2026 updates were both surgical — most notably Food Chain getting hit in Historic — and May 18 is the first window since the dust fully settled on Secrets of Strixhaven. With Pro Tour data, Regional Championship results, and a few months of Arena and paper play in the books, this is the announcement where systemic problems get addressed, not just symptoms.
Pioneer: The One Everyone Is Talking About
If something big drops Monday, our money is on Pioneer. The format is currently a two-deck conversation: Greasefang reanimator on one side, Cori-Steel Cutter Izzet Prowess on the other, with Golgari Midrange doing its best to act as a referee.
Cori-Steel Cutter survived the March announcement on a technicality and has only tightened its grip since. A one-mana equipment that produces tokens, applies pressure, and turns every cantrip into a clock is doing a lot of work for one card slot, and it has quietly defined what is and isn’t playable in red-based Pioneer. We think it’s the most likely single ban on the docket. Greasefang has its own case, but the deck is loud, well-known, and beatable when players come prepared — Wizards has historically given that archetype more leash than people expect.
Standard: Healthy, But Izzet Is Loud
Izzet Prowess ran the table at Pro Tour Secrets of Strixhaven, posting roughly 30% of the metagame share with Mono-Green Landfall chasing at ~19%. Here’s the wrinkle: no single Izzet variant posted a runaway win rate. The deck is popular, not broken, and that distinction usually saves cards from the chop.
Flow State is the new Prismari card juicing the archetype, but it’s a build-around, not a free win. We expect Standard to come out of May 18 untouched — and we’d encourage you not to panic-sell your Izzet staples until the announcement actually drops.
Modern, Legacy, and the Quiet Formats
Modern is in arguably its best place in years. Boros Energy is the consensus top deck, but the gap to the rest of the field is narrow, and nothing in the format is producing the “my opponent didn’t get to play Magic” patterns that historically trigger bans. We expect no Modern action.
Legacy‘s perennial bogeyman, Oops! All Spells, is naturally cooling off as the metagame adapts — Wizards explicitly called this out in the March update. Combined with their stated philosophy that “Legacy is unique” and shouldn’t be over-curated, we expect no Legacy bans either.
Pauper is fast enough to police itself, and the Commander Format Panel just updated in February, so we don’t anticipate movement on either side.
Our Predictions in One Breath
- Pioneer: Cori-Steel Cutter banned. Greasefang stays — for now.
- Standard: No changes.
- Modern: No changes.
- Legacy / Vintage: No changes.
- Pauper / Commander: No changes.
- Wildcard watch: A small Historic or Alchemy adjustment is the most likely “surprise” on the list.
What It Means for Your Collection
If you’re holding Cori-Steel Cutter copies you don’t need for a deck, this is the weekend to make a decision. If you’re holding Izzet staples, breathe — the panic discount on Monday morning is usually the buying window, not the selling one. And if you’re a Greasefang main, keep your sideboard sharp; even without a ban, the format’s answers are getting smarter every week.
We’ll be posting our reaction the moment the announcement goes live tomorrow. In the meantime, stop by The Vault — our singles selection is stocked up on the pieces of whatever the post-ban meta turns out to be, and we’d rather you find them with us than scramble on Tuesday. See you on the other side of the announcement.
