Oh Hi Mark,I just saw the post about Sheldon's spellbook. Was there discussion on doing it as "Commander Collection: Sheldon" as opposed to the retired spellbook naming. Commander being his area and the cards including matching the commander collection formatting (sol ring and command tower) more than the spellbooks (planeswalker with corresponding cards from that character)

I don’t know the specifics, but I do know Sheldon was involved in the early planning.

UnRules Question: What counts as a sealed booster? Can I use something like a Signature Spellbook since it has a randomized card as one of the slots in it, or does having mostly guaranteed slots disqualify it?

It has to be a sealed randomized booster. Signature Spellbook is not that.

i find the decision to introduce cards with spellbooks really odd. every time i see one of these cards that references a spellbook i immediately get exhausted. the card doesn't explain what it does thoroughly enough and having to remember an entire list of cards for each spellbook seems so unfun that i just immediately stop reading the card.

That’s why it’s a digital only card, because we wouldn’t expect you to do that in paper. On a computer, it’s much easier to reference information.

While I know this isn't your domain, I was disappointed in the changes to "The List" for Strixhaven. Kaldhiem had numerous cards with Player Rewards art, Signature Spellbook art, etc. The Strixhaven choices were almost all from their original set. Could I please request more of these alt-art reprints in future iterations? They're a really nice consolation for not opening the "big" cards on the list.

I’ll pass along the note.

Imagine that there was to be a Signature Spellbook: Mark Rosewater which will contain 8 cards; you are the sole person responsible for putting the cards into it. You allowed no more than 2 colors, a maximum of one colorless artifact, and a maximum of one silver-bordered card. What would your 8 cards be?

That’s a great question, but one I’ll fans think about. The two obvious answers are Maro and Doubling Season, so one of the colors is green.

Where and when can we find out more about Jumpstart and the Signature Spellbook?

I promise we will give you the info when there is info to give.

Is the next Signature Spellbook after Chandra one for B.O.B.?

Who else could it be?

Re: questions about future products. AFAIK we don't know the exactly order the announced products will be released. Is the following correct? 0 Theros (practically released by now), 1 Secret Lair Year of the Rat, 2 Unsanctioned, 3 Ikoria + 2020 Commander, 4 Core set, 5 Green Spellbook, 6 Zendikar, 7 Commander Legends.

I believe that is correct, but I don’t have the official schedule in front of me.

When do we get Signature Spellbook: Mark Rosewater? And what will be in it?

What would you all expect in it?

Oracle En-Vec always stood out to me as a Legendary "that could have been", as it is a very story important character. How likely will we see in the future a errata where certain creatures that really should be Legendary (including Nephilim cough cough) being redone so? I think it would be easy-ish with a simple reprinting of some of them in a package much like Gideon's spellbook, giving them also a foiling if need be and MAYBE alternative art.

Note that the story was referring to the current Oracle en-Vec, but it was a role filled by many individuals over time.
