Hi Mark, while looking up the Shichifukujin Dragon I did not see anywhere that it is on the reserve list. Could a functionally identical version be made? I'm assuming the intent of the cards function is not to die with the enters trigger on the stack :p

It is one of two Magic cards that only one exists in the world, so I do not expect it to get reprinted. I do know as the person that designed it, it was more about being cool to read than play.

Would saying that Baldur's Gate Wilderness is the same sort of "card" as Garruk the Slayer and the ones made for Theros block's Hero's Path be an accurate statement?

Yes.

“What other silver border cards are people interesting in seeing become Eternal-legal?” Uktabi Kong! I both rule0 him and see him played with some regularity

He could easily be Eternal-legal.

I've been playing Standard on Arena, and Master's Rebuke feels so much like Doom Blade it's stopped being funny. With the overall increased power numbers in green, bite spells feel very pushed, and frankly, they don't strike me as green feeling either. Could I request a return to fight spells?

The increase in bite spells comes from play design needs. From a color pie perspective, it still hits the core green necessity that green is reliant on its creatures.

Hi Mark, do you know why some cards such as Lazotep Sliver have the wording "Sliver creatures you control" while others like Rukarumel, Biologist have "Slivers you control"? This extends to quite a few creature types, and for some reason Regal Sliver even has both wordings.

When the Tribal card type was in regular use we used “<Creature Type> creatures”, but once that stopped we eventually went back to just “<Creature Type>”.

If or when: Sir Gynger, the Meal Ender, Mother of Cookies, the Sole Survivor of the Boiling Cauldron, the Last of Her Batch brings Garruk Wildspeaker to justice?

If she hasn’t already. : )

What made Uktabi Kong an un-card at the time? To me it seems completely fine within the rules.

It was more the flavor than the mechanics.

Oh hi Mark! It's my birthday, and I've come to invoke the sacred tradition of Birthday Trivia in hopes to learn a cool fact about the planeswalker, Kaito Shizuki! He's quickly become one of my favorite Magic characters, and getting to learn even a crumb of behind-the-scenes knowledge about my Boy would honestly make my birthday perfect! Thank you for everything you do here on Tumblr, by the way, you rock!

Kaito started as “blue/black Ninja planeswalker”. We’d talked about wanting to have a Ninja planeswalkers for years. Once we knew we were going to a Japanese-inspired world (it wasn’t definitely Kamigawa yet), we penciled it in. And it never left! Happy Birthday!

Why can't cards that do extra if you control a creature of a type, when they target a creature of a type, return to hand when a creature of a type enters the battlefield, etc. be tribal? I don't see a downside making cards that care about a creature type be tribal. Simple token creating spells don't care about the creature type so they wouldn't need to be tribal. For example Sosuke's Summons has a reason to be tribal and Krenko's Command doesn't.

It’s a matter of cost versus benefit. Adding a lot of words for minimal mechanical interaction isn’t a great trade-off.

Hi Mark. Unfinity ruling - when playing Ticking Mime Bomb in Britain can we use our national understanding of the word “pantomime” (musical comedy theatre - see Wikipedia page for pantomime for more details) rather than the separate concept of “mime” the card implies?

The intent of the card is that use mime rather than singing as singing what creature you want them to choose isn’t much of a minigame.
