While I don't think The Skyship Weatherlight qualifies as a character, it does eventually turn into Weatherlight Compleated which does seem to qualify as a character since it moves of its own volition even after it's powerstone was removed. The question comes down to whether naming the character will count the machine that became it. So for a similar question: If I name Memnarch with Vorthos, will it count towards cards with Mirari in them?

If you want to name Weatherlight as a character, I won’t stop your fun. Have at it. Memnarch can count the Mirari, why not?

To be fair, you've done an artifact representing the Mirari, but you've also done an enchantment representing the radiating waves of power coming out of the Mirari once it was part of a sword, so a second take on the Mirari, perhaps from a different point in time (like wherever in New Phyrexia it was sitting during that whole invasion), wouldn't be that out of left field.

The notes on that post do point out we’ve made multiple cards of many things, so yes, it should be an option.

I've noticed some artifacts and enchantments are very similar design-wise, such as Mirari's Wake and Forsaken Monument. It seems as though each could be the others' type, so why aren't they, or why isn't there more distinction? Does the set theme determine whether some cards are artifacts and others enchantments?

The same global effect can be on both an artifact or an enchantment. It depends on the flavor and the larger mechanical needs of the set.

Since all the Walker made planes were unstable unless they constantly managed, wont New Phyrexia collapse unless karn fixes it, that's assuming post Mending he has the power to fix it?

Most planeswalkers making planes didn’t have the power of the Mirari.

If/when: Return of the Mirari? Or Memnarch?

Major If. The Mirari is currently New Phyrexia and I believe Memnarch is dead.

Hey Maro the 27th is my birthday and I was wondering if you could tell me anything about my favorite flavorwise mirriodin.

The plane of Mirrodin was made by Karn when he was a pre-Mending planeswalker using the Mirari. Happy Birthday!

Regarding spells referencing the stack, I can only find four cards in Magic history whose printed rules text references it: Grip of Chaos, Mirari, Radiate, and Lightning Storm. Only Lightning Storm's oracle text still does, but, I'm not gonna lie, I have no desire to see anything similar in Standard.

The secret is that we can do all the effects we want without having to mention it.

The story about Mirari's Wake makes me wonder if the Mirari itself shouldn't have had those abilities. What inspired the idea of the instant/sorcery focus? Was it Flashback?

Mirari originally copied every instant and sorcery you cast for free.

For my birthday question today can you give us some trivia on the Mirari? I love how it's story unfolded and I hunger for more info as tho it's calling out to me. I even named my dog Mirari.

The Mirari came about because the story wanted an artifact of great power for the characters to lust after. Originally, the card copied everything for free but that proved too good. Happy Birthday!

For being an incredibly powerful artifact, the Odyssy Mirari doesn't seem really powerful in my opinion. Was it originally more powerful, or if not why did you choose to represent what the Mirari could do like that?

In design, the Mirari had no cost to copy spells. : )
