Hello Mark, I wanted to use my birthday ask to ask if a mechanic like Sole Performer could work in black border? I would also like to request Garruk come back to the story soon

Sole Performer is nowhere close to working in black border. Garruk should return one day. Happy Birthday!

Hi Mark!
Yesterday is my birthday. May I get trivia among one of my favorite cards - Worldfire, Wurmcoil Engine, Radiant Performer, Sundial of the Infinite, or Vizzerdrix? Or a random card from MH3 not covered by your previous Making Magic articles?

Vizzerdrix got created as a card for a product called Starter. The reason we made it is we had a series of TV commercials, one of which featured Kezzerdrix from Tempest (it involved mixing a wrestler, a chainsaw, and a bunny in a machine). A different ad in the same campaign used an Orgg. So to tie to those, we made a simpler Orgg and Vizzerdrix, as the original cards were too complicated for a beginner product.Happy Belated Birthday!

Now that Performer is a genuine creature type that appears on eternal legal cards, do you think we could see it in the Rakdos next time we visit Ravnica? I'd fit alot more than Warrior or Shaman like what they get typed normaly.

I hope it gets used.

can any Rakdos creatures from Ravnica get the Clown or Performer types in new prints / errata?

Maybe on a revisit. I’m skeptical we’ll errata anything with Clown or Performer.

is Sole Performer acorn for balance reasons?

Oh no. It doesn’t come close to working in the rules. It’s a good example of a mechanic that’s much more easily grokable by a human than a computer.

When Sole Performer adds the tap symbol, does it work like mana would? Would it get doubled by doubling cube? Or is it a seperate pool like energy?

It functions like mana for purposes of clearing, but it is not mana, so it is not doubled.

Will new creature types in Unfinity be errata'd onto existing creatures with that type in their name? Asking for Belligerent Guest, Gluttonous Guest, and Radiant Performer.

There is no current plan to do that.

Will we see Performer creature type outside of Un-sets?

All new creature types introduced in Unfinity (and there are a bunch) will be available for use in other sets, but their introduction isn’t a sign that they’ll be universally adopted.

On the note of clowns or a circus set, what colors would stage magicians fall into? and are there any other types of performers with interesting color identities?

Magicians would probably be base blue.

I know MTGO isn't really your department but I wanted to give some feedback on the decision to further reduce daily decklist data: it sucks. I read WotC's rationale but, frankly, I don't buy it. Obscuring and massaging the data makes it look like R&D is lying about the metagame because they can't balance it.

The problem is there is always a solved state to any metagame. In the past, the metagame would shifted before it got solved, but with new technology and access to data, it can be solved faster. In addition, there’s a snowballing problem where players look at the data and choose to play the strongest performer only further lessening the variety.
