Pioneer
The non-rotating format that starts at Return to Ravnica. Pioneer keeps modern-era decks alive without the fetchlands and dual-land power of older formats — a middle ground between Standard and Modern.
What is the Pioneer format?
Pioneer is a non-rotating constructed format introduced in 2019 to give players a home for decks built from the last decade of sets. Nothing rotates out of Pioneer, so a deck you build stays legal indefinitely as long as its cards are not banned. Pioneer sits between Standard and Modern in both power level and price: it is deeper and more powerful than the rotating Standard pool, but it deliberately excludes the fetchlands and original dual lands that define Modern and Legacy, keeping mana bases and combos more grounded. It is supported by MTG Arena’s Explorer format, which mirrors the Pioneer-legal cards available online.
Card pool and cutoff
Pioneer’s card pool begins with Return to Ravnica (2012) and includes every Standard-legal expansion and core set released since, plus supplemental cards that were printed in that window. The Return to Ravnica cutoff was chosen specifically because it marks the end of the original fetchland era in Standard — Pioneer intentionally has no Onslaught or Zendikar fetchlands, which keeps three- and four-color decks honest. As new sets release, they are added to Pioneer automatically, so the format only grows. This ever-expanding but curated pool is what gives Pioneer its identity: powerful, modern-feeling decks without the oldest broken staples.
Iconic and banned cards
Pioneer’s banned list is managed to keep any single deck from dominating. Over its history the format has banned high-impact cards such as Oko, Thief of Crowns, Once Upon a Time, Field of the Dead, Inverter of Truth, and Expressive Iteration to break up oppressive strategies. Iconic legal cards define the format’s pillars — efficient planeswalkers, powerful two-color removal, and resilient midrange threats. Because the banned list is periodically updated, a card that was legal last season may be banned now, so confirming current legality before deckbuilding matters. Premium and showcase printings of Pioneer staples often carry a price premium driven by both Pioneer and Commander demand.
How to check if a card is Pioneer legal
Scan a card with Tappr and its legality table — pulled live from Scryfall — shows exactly whether that card is legal, not legal, or banned in Pioneer. Since Pioneer legality depends on whether the card’s original set falls within the Return-to-Ravnica-forward window, Tappr resolves the specific printing you scanned and gives you a definitive answer, plus the current market price. That lets you quickly tell whether a card from your collection can slot into a Pioneer or Explorer deck.
Common questions
01 What sets are legal in Pioneer?
Every Standard-legal expansion and core set from Return to Ravnica (2012) onward is Pioneer legal, and nothing rotates out. Scan a card with Tappr to confirm whether its printing falls within that window.
02 Why are there no fetchlands in Pioneer?
Pioneer starts at Return to Ravnica specifically to exclude the Onslaught and Zendikar fetchlands. This keeps multicolor mana bases from being too consistent and preserves the format’s distinct identity.
03 Is Pioneer the same as Explorer on Arena?
They are closely related. Explorer is MTG Arena’s version of Pioneer using the cards available digitally, and the two are being brought in line as more of the Pioneer pool is added to Arena.
04 How do I check the Pioneer banned list for a card?
Scan the card with Tappr — the Scryfall-sourced legality table shows whether it is legal or banned in Pioneer, so you always see the current status rather than an outdated list.
