Why do Narset, Enlightened Exile and Bria, Riptide Rogue have different wordings for the same effect of giving all your creatures prowess?

Bria is our normal template. My guess is Narset didn’t have the text space to do the normal template, so it did the shorter one.

Did you guys use Freerunning instead of Prowl because you could put it on noncreature, non-Kindred cards? Would you consider it a "fixed" Prowl?Personally I like the open-endedness of Prowl. I feel like Freerunning forces you to rename the mechanic every time you want to use it with a different creature type, which could get pretty silly pretty quickly. I don't want to live in the future where we have several nigh-identical mechanics that do basically the same thing but all have different names. But I do understand why you guys want to avoid using Kindred.This is a tangent, but let me ask: Why was Prowl's first outing mostly only put on Rogue cards, when it was worded to work with any variety of creature types?

Because it was designed as a Rogue mechanic in Morningtide that had a class typal theme.

Hi Mark! About creature types. You’ve said before R&D is skittish about errataing creature types, but there’s been a lot of doing that anyway lately. Apart from changing the types of animal-people like viashino and cephalid to better synergize with their non-anthropomorphic counterparts, sloth was added to a few cards with Fallout, and now dragons from Kaladesh received the cat type. Efreet was phased out in favor of djinn, but not retroactively like naga - all the efreet cards are still efreet, but there won’t be new ones anymore. And lastly, despite both types entering the game around the same time, sloth gets added, detective doesn’t. Arboreal Grazer went from beast to sloth beast, but Dogged Detective stays merely a human rogue.  I’m fully in favor of the general direction that’s taken with creature types, and I also understand the risk of doing a lot of this in a game with paper cards. But the way it’s currently being handled feels extremely inconsistent, and the categorizer in me feels upset!
So, my question is: could you, or someone who is in charge of this, elaborate on the seemingly complex reasonings as to which creature type gets added, added but not errata’d, replaced, or phased out (perhaps in an article)? You’ve said before it’s not, but it really does seem scattershot, and I want to understand.Thank you!

Here’s the problem. It’s mostly done piecemeal which creates the inconsistency you’re talking about. Let me bring it up with the relevant people.

Hello Mark, hope all is well!I'm about to celebrate my 32nd birthday and would like to invoke the sacred rite of trivia from you! I got into this game when I was eight years old, someone in my class showed up with the iconic plastic baggy filled with a rubber band bound stack of little cardboard rectangles. I saw the card Root Elemental and was transfixed with the game ever since.Shortly after I found my way in a card shop and saw the absolutely mesmerizing Silvos, Rogue Elemental. I still to this day get a feeling of awe looking at that big green guy.So, do you have any hidden trivia on the pit fighter Silvos?Thanks for all you do for this game and for what you have done for me. Magic has been a very large part of my life for a long time, I appreciate your work and the work of everyone who has made it what it is.

Silvia is the largest regenerating creature at 8/5. The only other 8-power regenerator is Hunted Troll and it’s an 8/4 without trample (and gives the opponent four 1/1 blockers).Happy Birthday!

Hi Mark,It’s my birthday and me and my friends are going to play some OTJ sealed today. In honor of this, can I get some trivia on Outlaws, my favorite mechanic to come out of the set?

We made a list for Outlaw of any creature type that might make sense:

• Assassin
• Barbarian
• Berserker
• Minion
• Mercenary
• Ninja
• Pirate
• Rebel
• Rogue
• Warlock

Assassin and Rogue felt like automatic includes. We added Mercenary because we wanted the “henchperson” token to be a Mercenary. The creative team asked us to add Warlock because we needed to have an outlaw spellcaster to hit all the card concepts. That’s what we handed over to set design.When making a batch, we do between two and five, with three being optimal. Four seemed in a good spot and allowed set design to add something if they had to. They added Pirate because of all the Pirate cards in The Lost Caverns of Ixalan. We did talk through many of the others. We considered bringing Minion back instead of doing Mercenary (we stopped doing it a while ago). We talked a lot about Ninja. In the end though, we felt this collection best served the mechanic.Happy Birthday!

Hi Mark, once you decide to use Mercenary in creature cards in OTJ, was it too late to add some Mercenaries to other sets in standard?

There were enough Rogues, Warlocks, Assassins, and Pirates that it wasn’t an issue. Future sets can make use of the Mercenary creature type.

An assassin, a rogue, a mercenary, a warlock, and a pirate walk into a bar. What are they doing there together?

Having a secret batch meeting. Zendikar has similar party parties.

Not saying you got the set of creature-types wrong (and it, like "committing a crime" is a really cute concept, great job on those in recent years), but... Today I noticed that, while assassins and rogues are outlaws, ninjas aren't. Not saying that ninjas should be, but... You at least thought of it, right?

Someone didn’t read my article this week. : )

Outlaws of the Land, Part 1

Is flavor rule’s text going to be a thing now? The phrasing on Shoot the Sheriff seems oddly casual for rules text.

ALT

It’s reminder text. Reminder text is looser than rules text.

Loving things so far but a couple of questions, why weren't Ninjas considered outlaws and was clash considered for this set? The latter seems like it would fit flavor as a standoff with the higher cost being who drew and shot quicker.

Repeated batches, meaning things we use on multiple cards in the same set, are normally restricted between two and five items, with three being the sweet spot. We needed Rogues and Warlocks to hit all the creative executions we wanted. Mercenary was needed because that was our henchperson token. We also knew Assassin’s Creed with its Assassin typal theme was coming. We turned those four in when we handed off from vision, leaving one potential space open so set design could add something if needed. That something was Pirate due to all the ones added by The Lost Caverns of Ixalan. As I show in today’s article, we considered all the following:AssassinBarbarianBerserkerMinionMercenaryNinjaPirateRebelRogueWarlockThere just wasn’t room for all of them. Also, we prioritized what would be in the set. So some things, like Ninja, didn’t make the cut.As for clash, it’s just wasn’t popular enough when we first did it to bring it back.
