A format exclusive to MTG Arena, Historic includes all sets released on Arena. Like all formats it has a ban list, but it also has a suspended list. Cards that are suspended are not allowed to be used in deck-building, but the final verdict for whether the card should be banned or legal will be decided a little while later.
These cards cannot be used in this format:
Agent Of Treachery · Channel · Counterspell · Dark Ritual · Demonic Tutor · Field Of The Dead · Fires Of Invention · Lightning Bolt · Natural Order · Nexus Of Fate · Oko, Thief Of Crowns · Omnath, Locus Of Creation · Once Upon A Time · Swords To Plowshares · Teferi, Time Raveler · Thassa's Oracle · Uro, Titan Of Nature's Wrath · Veil Of Summer · Wilderness Reclamation · Winota, Joiner Of Forces
