Why was there no traditional planeswalker in modern horizons 3?

Because we used the slots for the DFC cycle that players have been asking for since Magic Origins. The set only got five planeswalkers, so if we wanted a cycle, we needed them all.

Maybe it got lost in the sea of questions, but could I get the coveted Birthday Trivia? About Arcades or about Kaledesh, as Arcades was my first commander, and Kaledesh was my first set!

Kaladesh, the plane, was originally created for Magic Origins because we needed to show Chandra’s home plane. We liked it so much we decided to make it a set and spent extra resources building it, so we’d be able to build on it a couple years later.Happy Belated Birthday!

"I call it a travelogue set." -- Would Magic Origins count as that as well? A set that explicitly takes place on multiple planes.

Sure.

Can I get a maybe on us getting a Magic Origins 2 featuring Garruk someday? :)

Maybe. : )

Is it plausible that there will be a set based around more than one plane simultaneously that doesn't involve interplanar war?

Like Magic Origins?

Hello Mark,I liked the theme of planeswalkers losing their sparks in Aftermath.Was there ever any thought about making “reverse” magic origins-style planeswalkers? (A planeswalker on the card front transforming into a creature on the card back)As far as we know, other planeswalkers are bound to lose their spark in the future, so Is that concept something Set Design might be interested to do?Thanks for reading!

We wanted to be consistent with how we did the desparked planeswalkers between sets, and not all sets have DFCs.

Hello Mark =), was the absence of a completly unknown plane in battle cards, hinting for a future expansion set, a deliberate choice? I know the design team loves to do that, recent Atraxa being a perfect example.

Yes. We talked about teasing a new world we were planning to go to, but March of the Machine was already a strain on the creative team, and that was dubbed too much extra work. We learned when previewing Kaladesh in Magic Origins, that it’s a huge amount of work.

If/When a one word standard-legal set name that isn't the name of a plane? Was the most recent one technically magic origins?

If, because we like to convey what plane we’re on.

Mark, if I may: I understand that this Phyrexian Arc actually started back in Scars of Mirrodin, just as the Bolas' Arc kinda started back in Shards of Alara, but the "ignition point" of the Bolas' Arc felt for me something around Magic Origins, which give us like 4 years of stories, while the ignition point of this Phyrexian contlict feels like Kaldheim but it had a pause until Kamigawa came out, which gives us like 1,5 years worth of stories. Maybe if we had like 2 years of development of this part of the arc things wouldn't feel that rushed.

The Phyrexian storyline has been subtly building for many years. Maybe it was a little too subtle.

If you did Magic Origins 2, are there any planeswalkers you'd personally like to dive into more? Living or dead, since they could be starting their journey here.

I have a soft spot for Kiora.
