Historic Pauper rules look simple from the name, but MTG Arena’s version has enough differences from tabletop Pauper to make old decklists and paper assumptions unreliable. The core idea is still common-rarity Constructed Magic, yet Arena uses the cards actually available in the client, Historic legality and its own event bans. That becomes especially important whenever Historic Pauper returns for Midweek Magic or a paid Challenge and a saved list suddenly fails the event deck builder.
The October 2026 events make a clean rules reference useful because the free and paid queues share the same underlying card pool while using different entry and reward structures. A player can practise in Midweek Magic and then take the same legal strategy into the Challenge, but only after the deck meets the Arena-specific restrictions. Knowing which rule comes from normal Constructed deck building and which one is unique to Historic Pauper avoids a lot of unnecessary rebuilding. Historic Pauper rules matter most when a deck comes from an older guide or a tabletop list, because neither source automatically reflects Arena’s current legality.
Historic Pauper rules for deck construction
At deck-construction level, Historic Pauper rules require at least 60 cards of common rarity that are legal in Historic on MTG Arena. Wizards allows up to seven cards in the sideboard for the October 2026 Challenge and limits you to four copies of a card across the main deck and sideboard, except for basic lands. A card with its own copy-number rule can still override the normal four-copy limit.
The safest way to build is inside the current Arena event or its deck filter. That lets the client flag cards that fail rarity, Historic legality or event-ban checks before you spend entry currency. It is much more reliable than importing a paper list and trying to diagnose every red card afterward. Following Historic Pauper rules means satisfying the common-rarity requirement and Historic legality together, which is stricter than simply filtering your collection to commons.
The current Historic Pauper banned list
The current Historic Pauper rules ban seven cards: Ancestral Mask, Cranial Ram, Galvanic Blast, Kuldotha Rebirth, Refurbished Familiar, Sneaky Snacker and Persistent Petitioners. Wizards repeated this list in its July 2026 Historic Pauper Challenge announcement after updating the format based on play data and community feedback earlier in the year.
Those bans matter even if the cards are common and otherwise available on Arena. Event legality sits on top of rarity and Historic legality, so a deck can satisfy the broad common-only idea and still be rejected because one banned card remains in the 60. Check old saved lists before assuming they survived unchanged between Historic Pauper weeks. The Historic Pauper rules ban list is short enough to check manually, and doing so before queueing is faster than rebuilding a deck after the client rejects key cards.
Historic Pauper is not tabletop Pauper
One of the most important Historic Pauper rules is conceptual: this is not the tabletop Pauper format running inside Arena. Wizards has explicitly said MTG Arena is nowhere close to parity with tabletop Pauper. The digital client has a different available card pool, digital-only content elsewhere in Historic and event-specific decisions about what the Pauper environment should allow.
That means a successful paper deck can fail in two different ways. Some cards simply are not available on Arena, while others may be legal in paper Pauper but banned or unsuitable in Arena’s Historic Pauper. Use tabletop lists as strategic inspiration if you want, but rebuild them against the client rather than treating them as one-click imports. This difference is why Historic Pauper rules should be checked against Arena itself instead of treated as another name for the tabletop Pauper format.
What counts as a common?
For Historic Pauper rules, the practical test is whether MTG Arena recognises the card as eligible for the event’s common-only pool. Rarity history across decades of paper printings can be messy, and the event filter is a better legality tool than trying to remember every historical printing. If Arena rejects the card, do not assume a paper common printing automatically overrides the event.
The same principle applies to reprints and special versions. Cosmetic treatments do not change the deck-building restriction, and owning a card does not make it legal. Build the list first around the event filter, then worry about which visual printing or style you prefer after the deck is accepted. Under Historic Pauper rules, common rarity is only one requirement: the card must also be available on Arena, legal in Historic and permitted by the event ban list.
Main deck, sideboard and the four-copy limit
The October Challenge version of Historic Pauper rules allows a minimum 60-card main deck and up to seven sideboard cards. Wizards counts the normal four-copy restriction across both zones. If you have four copies of a spell in the main deck, adding a fifth copy to the sideboard is not legal just because the zones are displayed separately.
Basic lands are exempt from that copy limit, and a card whose own rules text allows a different number can follow its printed exception. Because the Challenge is Best-of-One, the sideboard is not a conventional between-games transformation package. Keep the main 60 capable of executing the deck’s plan without assuming you will get a post-game swap. The sideboard limit is part of Historic Pauper rules even in Best-of-One because Arena can still use sideboard cards for effects that access cards from outside the game.
How Best-of-One changes deck building
Best-of-One changes what a sensible list looks like even though Historic Pauper rules do not tell you which archetype to play. Your starting deck has to face an unknown opponent without a game two, so broad interaction and reliable early plays are more valuable than a pile of narrow hate cards. Mana consistency also matters because a stumble consumes one of the few losses available in the paid Challenge.
A proactive plan helps for the same reason. You do not need to race every opponent, but your deck should know how it intends to win instead of relying on drawing perfect answers forever. The free Historic Pauper Midweek Magic queue is the best place to discover whether that plan works before you pay for a competitive run. Good Historic Pauper rules knowledge also improves deck construction by stopping illegal or overly narrow cards from consuming slots in a format decided quickly.
How to check a deck before entering
Before treating a list as finished, run a simple Historic Pauper rules check: at least 60 main-deck cards, commons accepted by the event, Historic legality, no banned cards, no accidental fifth copies across main deck and sideboard, and a mana base that actually casts the spells on time. Then play enough free games to expose problems the deck builder cannot see.
Keep this page as the rules reference and use the event pages for timing, entry fees and rewards. The underlying legality can return across multiple Historic Pauper events even when the surrounding prize structure changes, which is exactly why separating the evergreen rules from the October Challenge details makes the cluster more useful. A final Historic Pauper rules check in the live event deck builder is the safest way to catch legality changes before spending time or currency on a queue.
