Now we have Angelic Destiny and Draconic Destiny. Can I request for blue, black, and green Destiny? :)

Maybe. : )

Draconian Gate-Bot. Why is it a creature type Robot and not Robot Gate? Is it to avoid the acorn stamp? I now want to request Gate as a creature type.

Draconian Gate-Bot guards the gate. It is not the gate. Also, Gate is a land subtype, and while it’s both artifact and creature, Gate-Bot is not a land.

I really like the design of Stet, Draconic Proofreader lately. His design is quite different than a lot of other silver bordered cards. Could I ask a little about the thought process designing him and what is going on in his art?

When I was figuring out what we wanted the new cards to do in Unsanctioned, it dawned on me that we’d never had an Un-Dragon, so I allocated one of the red slots to be that. My note to the designers was I wanted the Dragon to have a job not associated with Dragons. I believe Ari Nieh was the one who made the first version of this card. She made it a proofreader because she liked the idea of having it remove text off of cards. The art, by the way, shows Stet (an editing term) turning “mice” into “ice” by cutting off the “m”.

Silver-bordered question: How does Stet, Draconic Proofreader interact with permanents that have multiple names? Do you choose which name to erase a letter from, or does it apply to all of its names? Also, if my friend were to legally change their name in the middle of a Magic game after I've activated Stet, would the ability carry over and still have erased the first letter of their new name?

It erases the first letter from the name of your choice. And how slow is your game that your opponent is able to change their name in the middle of it? : )

Un-rules question regarding Stet, Draconic Proofreader. My name is William Jake Allen Forbes, I have always gone by Jake, but as William is my legal first name it is what comes up when dealing with bureaucrats and any official paperwork. For determining if I am a valid target for the damage would Stet, being a bureaucrat, look at William or Jake? P.S. Unsanctioned looks amazing by the way, look forward to playing with it.

It goes by what your known as, not your official name.

Having Niv-Mizzet, the Firemind and Niv-Mizzet, Dracogenius at the same time wasn't "nice". Now there can be 4 in the battlefield. Can I ask how this was an improvement?

We took slight flavor hit to get a substantial gameplay gain.  This is very similar to what I call the “elephant in the boots” issue. If we wanted to be very flavorful, boots wouldn’t go on animals. The equipment would say something like “Equip humanoid”. I mean an elephant can’t get boots of speed on. But we decided that the gameplay was better if any creature could use any equipment.  Yes, at times it makes flavor that doesn’t make sense, but the gameplay was so much superior that we decided to suck up a slight flavor hit. Same thing here.

What are your thoughts on Niv-Mizzet, Dracogenius? Do you think he is too close to the original Niv, or does such a small change show realistic growth and change in a character?

I think he’s a fun twist. The cards might look similar but they play very differently and they require you to build very different decks.
