would wizards ever consider functional errata for cards to make them work In line with player expectations? ie, giving the Brothers Yamazaki a Partner With style ability so they can be used together in commander.

We’re more likely to make a new card than functional errataing an old one.

I thought one of the reasons why cards aren't printed with alternate art in the same set (like Brothers Yamazaki) was that is made it harder to players to easily distinguish which cards were which. I seem to remember this being a problem in older sets that had a bunch of cards with alternate art.

Fallen Empire had three or four arts for all the commons and not being able to recognize the cards was a huge problem.

Since you like to double stuff, was Brothers Yamazaki your design? (For those that don't know, it's the legendary Samurai who the Legend Rule didn't apply to if there were two of him on the battlefield)

I’m not sure. Having two arts was my idea.

If the legend rule were to be abolished, what would Brothers Yamazaki and Mirror Gallery actually say on them?

I don’t know. We’ve made rules changes that have essentially made cards do nothing before.

It's my sister and I's birthday! Can you tell us something about either of kamigawa's twins, the brothers yamazaki or Riku? or Timbor and Lumia? And speaking of which, why are all of magic's twins red? I mean aside from evil twin.

I had this cool idea to do two different arts for the Brothers Yamizaki, one of each brother. Only after the set was printed did I realize that it required an entire other sheet and was done at a huge expense which I would have stopped had I known. I don’t know why most twins have been red. It wasn’t planned. Triplets, though, are apparently green/white. Happy Birthday!
