Regarding colorless legendaries, the thing I most want with them is interesting effects that aren't about artifacts, with the legendary themselves costing a maximum of 6 mana. While Hope of Ghirapur is interesting, I don't think it's particularly fun as a commander, as in order to use it's effect, you must lose it-and pay 3 or 5 or 7 mana to get it back.

Not expensive but not undercutting any of the colors is narrow space.

Currently there are only 18 lands in Standard with a colourless colour identity (ie no colour mana symbols), excluding Evolving Wilds (no Wastes to fetch) and transformed lands (which don't really contribute to a deck's land count). I'd suggest that if Brawl has any colourless commanders legal (like Hope of Ghirapur or Karn), there should be at least 25 unique colourless lands available, or Wastes should be always be printed in Standard (maybe in Deckbuilder Toolkits).

It’s an issue that has been raised and I know R&D is going to talk about it. Brawl is a new format so it will have some early growing as we figure out issues. Input from all of you with concerns will have us figure out these issues.

Another question: After putting "Daunt" in Kaladesh with Elegant Edgecrafters and Ghirapur Guide, you have put it in Amonkhet as well with Greater Sandwurm. Is that a mechanic we can expect to see more of in the future? Does it play well enough to evergreen potential?

We like it enough that we’re using it at a low level. I’m not sure of its future.

Could we see more return blocks that explore new areas of the plane (like how Dominaria had many blocks on different continents)? In my opinion, it's more interesting than seeing the same thing again with a new threat, and it would be a good way to introduce things that people wanted but didn't make sense in the previously visited sections (ex. Rakhasa, Naga, and Atogs on Kaladesh, but not in Ghirapur). Also, there are supposed to be other types of lycanthropes across the sea on Innistrad.

Properties with a lot of worlds (“Star Wars” and “Star Trek” are good examples) need to give each world a very clear identity to set them apart from one another. Tatooine is a desert planet, for instance, and not a multi-faceted ecosystem.Early Magic staying in one place for so long was a mistake. Jamuraa should have been an African-inspired plane and not a separate continent.One of the things that has kept us from returning to Dominaria is trying to wrestle with a world that doesn’t have a cohesive identity.My point is that worlds having a strong, recognizable identity is a big plus especially as we add more and more planes to the game, so I don’t think we want to return to Innistrad and visit a continent that looks and feels completely different.
