The copy of Submerge in my blue binder looks exactly like a card from Nemesis in 2000. Mark Romanoski art, a guy getting swallowed by a wave, “48/143” at the bottom, the little Nemesis dagger symbol in the type line. And then in the bottom-left corner of the black border there’s a tiny white planeswalker symbol that has no business being on a card from 2000. That symbol is the planeswalker stamp, and it means my Submerge was printed in 2024 and is worth about a third of what I thought.

If you’ve bought a Secret Lair Commander deck, opened Mystery Booster 2, or pulled a List card from a Play Booster, you have some of these. Tomorrow you can buy 76 more. Wizards’ decklist for the new Secret Lair Commander deck, Odds and Ends, says its non-foil reprints carry “the same stamp used in products like Mystery Booster 2 and previous Secret Lair Commander decks.” It’s a $149.99 Esper deck led by Yennett, Cryptic Sovereign, with things like Fractured Identity and the gloriously weird Psychic Battle sitting in the stamped pile.

Which products use the planeswalker stamp

The stamp is how Wizards marks a card that’s been reproduced with its original face. Same art, same frame, same set symbol, same collector number as the printing it copies. The only difference is the glyph. On old-frame cards it sits in the bottom-left corner of the border like on my Submerge. On modern frames it’s on the bottom edge. I covered the original version of this in the post on The List, which was the product most people first saw it on.

It spread from there. Mystery Booster 2 in August 2024 used it on its reprints of old cards. Then the Secret Lair Commander decks picked it up for the non-foil cards that didn’t get new art: From Cute to Brute, 20 Ways to Win (74 stamped cards), Everyone’s Invited! (89), Goblin Storm, the Hatsune Miku deck, and now Odds and Ends. A deck usually has a dozen or two cards with new art or an updated frame, and nearly everything else is stamped.

The stamp also isn’t guaranteed. Wizards’ own decklist for the Miku deck points out two non-foil reprints printed without it, Growing Ranks and Phyrexian Processor, which means you can’t even assume a whole deck is stamped. Unstamped reprints in a stamped deck is a sentence that shouldn’t have to exist.

Scryfall files all of them under The List

This is the part that’ll trip you up when you log them. Scryfall puts Secret Lair deck reprints and Mystery Booster 2 reprints in the same place (the mb2 code only holds 385 cards, the playtest cards and special-frame reprints). Every stamped card goes into PLST, The List’s set code, with a collector number built from the original set and number. My Submerge is NEM-48. The Throne of Eldraine from Goblin Storm is WOC-28.

I pulled every PLST card Scryfall dates to 2024 or later and grouped them by date. The batches line up with product releases almost perfectly:

  • August 2, 2024: 1,355 cards, the day Mystery Booster 2 came out
  • December 2, 2024: 68 cards, 20 Ways to Win
  • May 12, 2025: 74 cards, Everyone’s Invited!
  • May 18, 2026: 70 cards, Goblin Storm
  • August 10, 2026: 61 cards, the Miku deck
  • November 9, 2026: 482 cards, lined up with the date Scryfall has for Mystery Booster Commander Edition

That fourth line answers a question I left hanging at the end of The List post. I’d found 70 red, very Goblin-heavy cards added to PLST in May 2026, more than a year after The List stopped showing up in packs, and couldn’t work out where they came from. It was a Secret Lair Commander deck the whole time. Goblin Matron, Goblin Warchief, Goblin Bombardment. I was apparently the only person confused. The Goblin Storm post went up the same week, and I didn’t connect it.

In practice, if you look up a stamped card by its set symbol you get the original printing, and the original printing is usually the wrong price. The check that actually works is the one I keep nagging about: read the collector line, then look at the corner for the glyph. If the glyph’s there, you want the PLST entry with the matching SET-NUMBER.

Is a stamped reprint worth less?

It depends which product it came from, and the split is bigger than I expected.

For the Secret Lair decks, barely. I compared every stamped card from 20 Ways to Win, Everyone’s Invited! and Goblin Storm priced at $3 or more against the exact printing it copies. There were 39 of them. The median stamped copy sells for 99% of the original, and 20 of the 39 are cheaper while 19 aren’t. Throne of Eldraine is $29.12 stamped against $32.45 for the Wilds of Eldraine Commander copy. Seedborn Muse is $18.14 against $18.61. A couple go the other way entirely: the stamped Magda, Brazen Outlaw from Everyone’s Invited! is $15.09, and the Kaldheim original it copies is $9.50. I don’t know why. Probably fewer people bought a $199.99 party-themed Morophon deck than opened Kaldheim.

Mystery Booster 2 is where it goes sideways. Same test, 45 cards at $3 or more, and 42 of them are cheaper than the printing they copy. The median stamped MB2 card sells for 81% of the original. Some of the individual gaps are brutal:

So an MB2 stamped card isn’t just cheaper than the fancy old version it’s pretending to be. It’s often cheaper than every unstamped version of the card, which is a pretty clear sign the market treats it as its own lesser printing.

I went back and forth on whether the stamp is actually the cause. MB2 put 1,355 different reprints on its sheets, and the cards it copies are often old ones that carry some “original printing” premium of their own. Maybe the stamp has nothing to do with it and this is just supply against nostalgia. Then I looked at Price of Progress again. There’s an older stamped copy on The List, the one reproducing the Eternal Masters printing, and it’s $5.44, still under the $8.14 Eternal Masters card. Two different stamped runs, both below every regular copy. The stamp costs something on the older cards, and I’d guess the Secret Lair decks get away with it because they mostly copy printings that are only a few years old and were never special.

Anyway. The Submerge. I pulled it from an MB2 pack at a draft night at a store in Leeds, a week after release, the whole table cracking packs at eleven quid a go. I held it up and announced to the table that I’d opened a real Nemesis card, because I didn’t know about the stamp yet and I thought MB2 was, I don’t know, a mystery box of genuine old cards. Someone sitting across from me, very kindly, didn’t say anything. I found out months later when I scanned it and the price came back at a third of what I’d been telling people.

What to do with the ones you own

Honestly, for most of these, nothing. So you’ve got a Secret Lair Commander deck, it’s sleeved up, it’s in a deck box. Fine. It’s the same card for play, and for the Secret Lair ones the price is basically the same too. Leave it.

It starts to matter when you total up your collection or trade one away. If everything in your spreadsheet is logged as the original printing, your MB2 cards are overvalued by something like a fifth on average and much worse on individual cards. If you’re trading, the person across the table might price your stamped Price of Progress at $10 because it says Exodus on it, and they might not. You won’t know which until afterwards.

A card list in Eldwyn showing collection entries with set codes

I scan stamped cards in Eldwyn the same as anything else and then check that the entry says The List with the hyphenated number. For the old-frame ones that’s where it’s most likely to go wrong, since the card itself is telling you it’s from 1998. The Mystery Booster Commander Edition batch sitting on Scryfall for November probably adds another 482 of these. Odds and Ends adds 76 more whenever it ships, which for anyone who misses the first batch is July 2027. None of those have prices yet, and I’m curious which pattern they follow.
