If/when reprint panglacial wurm as an acorn card

If. I don’t think we have plans to turn eternal cards into acorn cards.

To illustrate that every person has a different line for what's a "real" Magic card, my line is cards that can't easily be ruled on if you know the comprehensive rules. Most, but not all acorn cards cross the line, as does Panglacial Wurm. I do like a lot of nearly black border acorn cards, and even ask to include Gift Shop and Push Your Luck in my attraction deck. Universes Beyond as a line in the sand does not matter to me.

How do you feel about Tug of War? It wasn’t acorn because of rules (the Rules Manager said we could make it eternal), but because it didn’t feel right being eternal.

Why isn’t panglacial Wurm acorn

It probably should be.

What happens if a series of replacement effects make a mana ability that we activate while casting panglacial wurm from our library to cause us to search our library?

The Space-Time Continuum breaks. : )

Panglacial WurmI've seen sufficient debate from rules experts about whether or not Panglacial Wurm actually functions within the rules - or if it's merely accepted as an oddity and any possible rules issues brushed off. Regardless, it's odd such a nebulous rules space is permitted for a the benefit of a single card.Has WotC ever considered an erratum to tweak the rules slightly? What were the strongest arguments and obstacles that came up?Example erratum: "While you're searching your library, you may exile P.W. from your library. When you do, you may cast it from exile."This could alternatively be a rules update that formally defines how 'casting while searching' works. This particular version would have mechanical distinctions of possible relevance, but I believe it would preserve the vast majority of the card's function while making the rules surrounding it more straight-forward.

Sometimes we do something that we retroactively realize we shouldn’t have done. Our general strategy is to avoid doing it again rather than double down on figuring out how to make it work a little better.

Has R&D ever considered banning in every format such cards as Panglacial Wurm that put a huge weight on the rules?

If Panglacial Worm was causing competitive tournament issues, we’d probably react differently.

If un-acorning old cards is on the table, is acorning old cards also on the table? How about Panglacial Wurm?

That’s not currently an option.

If/When Panglacial Wurm on Arena!

If. The rules have major issues with it.

Has there ever been some consideration of taking a few of the cards that basically don't work in the rules, ones that have persistently needed whole sections, stuff like Panglacial Wurm, and shifting them into the Falling Star/Shahrazad and such category, cards just deemed... Well, you know. Basically, "we shouldn't have printed this card and every rules-manager's job gets harder because of it, so now it's gone forever"? If a rules-manager proposed that, would they succeed?

There have been a number of calls to ban Panglacial Wurm in every format for rules reasons (aka it doesn’t kind of technically work).

Any chance Panglacial Wurm getting errata to be acorn, since it doesn't really work within the rules?

We’ve yet errata a non-acorn card to be acorn. Although we have banned a few things and made the category acorn (things like physical dexterity or subgames).
