Does mono-red get outright kill spells? If not, why make this color-pie break?

It doesn't. In fact, the damage that red deals to creatures is often hindered before it hits really big numbers since that tends to be the same result as 'destroy target creature' (there are obvious exceptions.)

Based on the name of this card, it looks like Onygox is referencing the classic card Fissure from The Dark, and reprinted in 4th edition. Interesting that he/she decided to make the card cheaper and give a bonus ability, even if this is mythic (though, Fissure is an instant.) It's not how I would do things, but I figure the choices made were deliberate and knowing.

Not only is this not (and never was) in color pie, it's not a very interesting mythic. Rare, maybe, if it was BR

Sometimes, I think even WotC confuses 'powerful' with 'interesting'.

Mythicness - eh... there's a whole tranche of players who like big explosions. This would need a better name (referencing a known character - which; ugh; means chadra the dull and uninteresting) and really really nice shiny artwork. But that could be ok.

Mono-black would get this with a single word change: Destroy -> Sacrifice.

But yeah, this is out of pie since they started enforcing a pie.

So the obvious fix is to give it a really big number instead of destroy. That both appeases the pie somewhat, and also puts a really large number on the card, making the michael-bay psychographic even happier.

And sure, it's a win combo with Stuffy Doll. That's probably fine.

In terms of color pie, I found two recent mythic red spells that can kill creatures - Indomitable Creativity and Descent of the Dragons. In terms of power, the precedent I was inspired by was Fiery Confluence which can kill an artifact and deal 4 damage to each opponent for a similar price.

I hadn't actually realized that Fissure existed so thanks for that reference. I do know that this isn't a big splashy mythic - a better name and/or flavor should help with that - and I realize that destroy isn't usually in red's color pie. Perhaps I should change it to direct damage instead.

Red explicitly gets "Baleful Polymorph" now i. e. it gets to destroy creatures if (and that's hard requirement here) it "turns them into something else". The first card printed under this new paradigm was IIRC Divergent Transformations.

Transforming the creature into absence of a creature or a worthless pile of ash does not qualify.

Yeah that makes more sense for red. If I change the name I could use that effect as well.

Wha... you didn't know about Fissure? That's some crazy coincidencing! It's like you did a mashup of two cards without even knowing the first one existed...

The card's name doesn't quite fit any more though. Maybe something... "reforge"? With great forge heat causing damage?
