What is the likelihood that a “subgame” effect like Shahrazad or Karn Liberated will ever get printed again? Separate answers for standard legal and supplementary product

Subgames are now silver border only due to tournament time constraint issues.

In response to: "Would a Planeswalker ultimate that got rid of opponent's emblems ever be considered?" There is already a planeswalker ultimate that does this: Karn Liberated.

Fair enough.

In From the Vault Lore, why wasn't Karn Liberated included? He just seemed like the perfect inclusion: His -3 ability refers to the Legacy Weapon, His Ult refers to his ability to time travel, AND he was one of the central figures in MANY of MTGs stories... The perfect combination of power and lore.

We only had fifteen slots and lots of choices to fill them.

So given that there have been more than a few supertype crossovers lately that were a bit unusual (like Enchantment Artifact, Enchantment Creature, and further back land creature), do you believe there is any design space for something like an Artifact Planeswalker or Enchantment Planeswalker? Granted, if you did believe so, Karn Liberated may have had an Artifact supertype, but let's imagine a future possibility, like Heliod or Erebos becoming a planeswalker.

The reason for not crossing them was mostly developmental. Once you start letting Planeswalkers be Artifacts or Enchantments, you open up a lot more potential abuses.

Why is "destroy target permanent" unacceptable in green but acceptable in brown? A monogreen deck can cast a Karn Liberated just as easily as it can cast a Desert Twister.

Some color definitions come from the inability to do something. A color philosophically being able to do something and a mono color deck of that color getting access to it are not the same thing. For example, green is not supposed to destroy creatures but I believe artifacts should have that ability. Yes, a green deck can use those artifacts but then green is forced to go outside of green to do it.

Will we see Karn again? Such a great character, I hope Karn Liberated wasn't the only time he'll be around!

I doubt we’ve seen the last of Karn.

Hi Mark. The mechanic I'd like to see returned is the snow mechanic. My favorite block was the Ice Age block (including Coldsnap!). Being an old-timer, of course, Time Spiral is a close second. My question: Who designed Karn Liberated and Karn, Silver Golem? Karn holds a special place in my heart - my middle name is Karn.

I’m not sure who designed Karn Liberated. My best guess is Ken Nagle as it was his set. I designed Karn, Silver Golem. Also, I designed the character of Karn back when I was one of the two people in charge of the Weatherlight Saga.

Are planeswalkers designed by individual designers? Is there a planeswalker card you can say you designed? Also, who designed Karn Liberated?

Planeswalkers tend to go through many iterations so more people get their fingerprints on them. For example, I have had a hand in many planeswalkers but there isn’t one I feel was solely my design.
