I know this question is an intersection of two things WOTC doesn't pay too much attention to (which is fine), MTGO and Legacy, but now that cards are being regularly printed in supplemental products like Neon Dynasty Commander which are Legacy playable, can you pass on a request to make the cards more available in MTGO somehow? This has been an issue since True-Name Nemesis but is becoming more impactful as more cards are printed. On behalf of the MTGo and Legacy communities thank you :)

I’ll pass along the request.

"We will have a lot of data to crunch. Note that a card/mechanic can be disruptive in competitive play, but be beloved and played a lot in casual play." For a set aimed at Standard, such a mechanic evidently qualifies as a mistake. Monarch is a great casual mechanic - but in Legacy where it's hard to remove the monarchy it's free white card draw. You still seems to focus too much on playtesting mechanics as intended, not how they'll be used in competitive settings (Exhibit A: True-Name Nemesis).

We do not have the resources to test every format. We test cards primarily for the lowest powered and most sanctioned formats, Standard, Sealed and Booster Draft, and use other tools to balance older formats if cards cause issues. (Note we do test for formats if the set is aimed for the format - with things like Commander products and Modern Horizons.)

in your podcast about not designing just to prove you mention it's important to design for your target audience. Would you say that the inclusion of True-Name Nemesis, which is a mediocre multiplayer card but an eternal staple was a mistake in Commander 2013?

Yes, I do believe in retrospect it was a mistake.

Re: a supplementary Commander product - One of the reasons that people feel that they can't get into Commander as much is because of the price tag, even for the starters, and especially if one of the cards becomes the next Flusterstorm or True-Name Nemesis. What if there were Commander products in boosters to increase availability like Modern Masters?

A fine question. Would you prefer the Commander products as is or in booster form?

Today is my birthday! Can I get some trivia about True-Name Nemesis?

The inspiration for the design was something that would play uniquely in multiplayer play. I’m pretty sure the person who designed it (Mark Gottlieb I believe) wasn’t thinking about two-player play. Remember, by the way, that the numbers on it changed during development.Happy Birthday!

If you don't like Commander Eesha because protection from creatures makes the game uninteresting, what do you think about True-Name Nemesis?

I’m not a huge fan of the design. I’m kind of keen on player interaction. In fairness to the design, it was created to be played in a multiplayer format where the card was supposed to have interesting political ramifications and was much easier to deal with.

I recently witnessed another player "blame" you for True-Name Nemesis. But if I recall correctly you did not contribute to Commander 2013. Am I right?

That is correct. I neither made the card or even worked on the product it appears in. As official scapegoat, it is though completely my fault. : )

Would thought be given to having True-Name Nemesis receive Errata to sustain its functionality in multiplayer games but not entirely apply to 1v1 games?

That’s not how we want to use errata. 

Was True-Name Nemesis created for Leacy, because it is really bad in multiplayer commander but really amazing in Legacy?

It was created for Commander and then costed with Legacy in mind.

Desptite being in the Commander decks, it's pretty obvious that True-Name Nemesis was not designed for EDH. He's inarguably worse in multiplayer, and a 3/1 isn't impressive in the wrath-heavy, 40-life, battlecruiser format that is EDH. What say you?

I talked to the card’s designed, Mark Gottlieb. He says he designed the card for Commander. Did development possibly push its numbers for Eternal formats? I don’t know but maybe. Was he designed for Eternal formats? No.
