Hi Mark, I'm hoping you can help settle this now that spoilers have started. Is spree considered a kicker variant, or a split card (with fuse) variant?

Spree is more like a three-card split card with fuse.

We've seen several iterations of traditional split cards. Is there a particular reason why we haven't seen fuse again? Design or play issues? Is it still a 5 on the storm scale?

Fuse cards force us to make the base effects cost more, so the card really wants you to fuse it, which means it gets played less.

We have seen many split cards since Dragon's Maze, what happened to Fuse (other than on a single Commander card)?

It’s something we use sporadically.

I would like to express my disappointment in the flavor failure of not making Push//Pull fuseable alongside Fuss//Bother. It just seemed like a missed opportunity. Unless there is just some storm scale issue that I don't know about with fuse.

The split cards in the set don’t have fuse (as is the default for split cards).

The limited sets in the past 4 years have been unbelievable! I have been having an absolute blast, I have drafted them all! I was crushed to hear that draft boosters were going away. Why were draft boosters added, taken away, and replaced with play boosters? With the additional rare slot and less commons to fuse with the now obsolete set boosters, it feels like the push to make everything more profitable is creeping into limited play. Some things I like about limited 1) Each set is usually not impacted by must-have or oppressive commander or modern cards. 2) I like is that it's common centric. 3) I like that there is a lower frequency of rares. 4) low cost of entry, 15 bucks at my local lgs, 10 on Arena. In general, I am not happy about the limited booster changes but I will wait to try them.I am concerned that one day limited will be deemed "not profitable" and this golden age will end.

Play boosters are us ensuring that draft continues on. Draft boosters were selling so poorly, they were eventually going to be eliminated. We took steps to make sure you can keep drafting.

Why does read ahead have limited design space? It seems like it could go on any saga. Is it power level? Maybe the same could be said for fuse and split cards.

It can’t just be put on any Saga, not without changing the mana cost. Read ahead Sagas need to have a nice balance of effects where you are tempted to skip ahead, but not structured such that you always do so. It’s a delicate restriction to design to.

Where do each of the "2 cards in 1" mechanics fall on the storm scale? Things like the Fire//Ice classic split cards, but also things like Aftermath, Fuse, Transform, Flip and the Modal Dual cards.

Each one of those is a different thing.Split cards are a 2, as they’re deciduousAftermath is a 7, as the frame was much disliked (I can see us doing something similar but reworking the frame)Fuse is a 5, as it’s a mechanic that only goes on split cards.Flip cards (the Kamigawa mechanic) is a 9.TDFCs and MDFCs are also a 2, as they are also deciduous.

Do modal double faced cards still leave room for new traditional (not fuse/aftermath/adventure) split cards in magic? Do modal double faced cards do the same job but better?

We purposefully didn’t do modal double faced cards that are instants and/or sorceries on both sides because split cards do it without needing the second side.

Are Makakir Rebirth / Infuse with Vitality effects theoretically in pie for either white or boros?

I believe White could get Malikir Rebirth, but probably without the life loss and Infuse with Vitality without the deathtouch. I don’t see what red adds to either.

On MDFC/Cassette cards, does this mean we won't be seeing split cards without a split-specific mechanic (Fuse, Aftermath, Adventure, etc.) in the future? Since they do pretty much exactly what those cards want to do, but better, it seems?

Spllit cards have the advantage of being single-faced. They have the disadvantage of only being instants and sorceries. We should see basic split cards again.
