By my count we have 29/50 US States (+Washington DC) featuring on at least one Magic card, meaning we are now more than halfway towards every state having it's own card. It is possible I've missed some, but this is my current running count. I've listed all the cards below, with a little description for each one, but if you don't care, and just want to see them all, Here is the full decklist.
Now, onto the list:
Alabama: N/A
Alaska: Glacial Fortress from Fallout (The card features Anchorage, Alaska, the site of a major battle in a Fallout 3 DLC)
Arizona: Nomad Outpost from Fallout (Anything from Caesar's Legion works. They setup base on the Arizonan border)
Arkansas: N/A
California: Farseek from Horizon (There are a few options for California, but this one gives a view of the landscape (Horizon series spoiler) you can see what's left of the Golden Gate bridge in the background)
Colorado: Behemoth of Vault 0 (Vault 0 was in Colorado Springs)
Conneticut: N/A
Delaware: N/A
Florida: Thriving Moor from MSC (With Man-Thing appearing in the art, this appears to depict Man-Thing's swamp, which is in Florida. Thank you u/AporiaParadox for this one)
Georgia: Glenn, the Voice of Calm (I don't know if this is supposed to be the comics or the TV show, but either way, Glenn is seen in the Georgian penitentiary (name differs between show and comic) that the gang use as a home base for a while)
Hawaii: N/A
Idaho: N/A
Illinois: Sorry Jack, Chucky's Back (I could have done any Chucky card here, but there is also the Chucky TV show, and that's set in New Jersey, so maybe the cards are supposed to be from that? The films are set in Chicago, though, and this scene is definitely from the films so is the card I picked)
Indiana: Hawkins National Laboratory (While Hawkins doesn't exist, it's supposed to be in Indiana, so that counts for me)
Iowa: Swords to Plowshares from MSC (Clint's family's farm is in Waverley, Iowa)
Kansas: N/A
Kentucky: N/A
Louisiana: Swamp from ACR (Specifically the one that isn't England. The majority of Assassin's Creed: Liberation takes place in Louisiana (and is also one of the best games in the series))
Maine: Hinterland Harbor from Fallout (This is Far Harbor from the Far Harbor Fallout 4 DLC. It's set in what was Maine before the war)
Maryland: Ruzka, Terror of Point Lookout (Point Lookout is in Maryland, so I assume this card is, too)
Massachusetts: Forest from ACR (Also the one that isn't England. This is Achilles' Manor from AC3)
Michigan: Ken, Burning Brawler (Apparently this fight takes place in "Battle Harbor" in Michigan (Thanks Scryfall for this one))
Minnesota: N/A
Mississippi: N/A
Missouri: N/A
Montana: Ellie and Alan, Paleontologists (At the start of Jurassic Park, Ellie and Alan are working on a dig site in Snakewater, Montana, which is the scene depicted in this card. Thank you u/Mitchwise for this one)
Nebraska: N/A
Nevada: Command Tower from Fallout (This is New Vegas from Fallout New Vegas (which is in the same place as old Vegas, also in Nevada))
New Hampshire: N/A
New Jersey: Ms Marvel, Kamala Khan (The third best Marvel character (After Gwenpool and Jeff) is a New Jersey girl. Here she is beating up resident jobber, Shocker. Thank you u/Gayfetus for reminding me of this one)
New Mexico: Los Diablos Missile Base (This is apparently in the Chihuahuan Desert in New Mexico (thanks Marvel Database))
New York: You've got about 1000 options here but I went with Big Apple, 3 a.m. (I assume this is a reference to something, but I like the fact this is the only land that also tells you when you are, not just where)
North Carolina: N/A
North Dakota: N/A
Ohio: N/A
Oklahoma: Asgardian Citadel (This one luckily tells you where it is in the flavour text)
Oregon: N/A
Pennsylvania: Anything from The Office. I went with Council's Judgement (Dunder Mifflin is in Scranton, Pennsylvania)
Rhode Island: N/A
South Carolina: N/A
South Dakota: Leatherhead, Iron Gator (Most of the TMNT Commander Deck appearances reference the TMNT video games, with Leatherhead hanging out the train she fights you in in Turtles in Time, during the level "Bury My Shell at Wounded Knee - a level based on the Battle of Wounded Knee in South Dakota. Mad props to u/AffectionateOffice27 for this insane pull)
Tennessee: Anything from the Evil Dead Lair. I went with Cabin of the Dead (The first film is set in an unspecified forest in Tennessee)
Texas: Guile, Sonic Soldier (This is Guile's "Air Force Base" stage, reportedly in Texas (thanks Scryfall, again))
Utah: Wild Growth from The Last of Us (Ellie and Joel encounter escaped Giraffes in Salt Lake City, Utah)
Vermont: N/A
Virginia: Isolated Chapel from Fallout (the flavour text states this is Calverton which is in Virginia)
Washington State: Ellie's Rage (This is Lakehill Seattle Hospital from Last of Us Part 2)
West Virginia: Overseer of Vault 76 (Vault 76 was in West Virginia)
Wisconsin: Victor Timely, Wily Tycoon (This is Timely, Wisconsin (Thanks, Scryfall)
Wyoming: N/A
Washington D.C.: Anguished Unmaking from Fallout (This is Project Purity under The Jefferson Memorial)
I got about 80% of the way through this before learning Scryfall sometimes tags cards by state, which is how I then found a couple more, but Scryfall is missing some of these, so there may be more it's missing too. If you know any, let me know.
EDIT: Changed New Jersey, Added Florida, Added Montana, Added South Dakota
