Hello! I'm a huge mono-Red fan and my special interest is Fire. (I've been a fan of MtG ever since I saw Ashling in a Lorwyn ad. Flamekin are my favorite!!) I'm eagerly looking forward to the reveal of the WildFire Calamity Beast's card! My question is: Can we please get a yes/no/maybe on the possibility of upcoming mono-red Fire elementals?

I can only say we make them from time to time and I expect us to make more in the future.

Is it correct to say that in a block like Urza Block the design philosophy was centered on creating build-around cards? Many cards in that block created a deck that could be built around a single, unique card. Example: Bargain. Wildfire. Tinker, Enchantress. Replenish, Opposition etc. It seems to me that nowadays you rather focus on "pre-assembled" groups of cards, rather than single cards. (I don't like it).

No, it is not correct to say that. You are comparing apples and oranges. Urza’s Saga was released in 1998, just five years into the game’s life. There was much less need to differentiate itself from the other sets, because it was in the low two digits. Strixhaven, in contrast, is twenty-eight years in and has triple digits of sets to be compared against. It has to have a stronger, cohesive mechanical identity to be memorable.Both sets had plenty of Standard build-around cards. Where they start to deviate is in larger formats. That’s the result of two big factors. One, it’s easier to make a dent in a format of five years of cards than twenty-eight. Two, Urza’s Saga’s power level is through the roof. It’s the most powerful expansion set ever printed. It’s a lot easier to get cards played when the power level is through the roof.So, yes there are differences, but none of it comes from a design intent to make less build around cards.
