Your counterargument to Jace not being shoved into SOI was that they created a deliberate narrative that needed one of the group there and Jace was the only option.
That's not falsifying claims but explaining why they did it.
I mean, I'm answering the question "how was Jace narratively necessary in SOI," I explain the big bunch of ways they set it up, and the response is "yeah but he's a poopy head so they shouldn't have done that." Ok?
Considering Jace had 7 renditions and 1 appearance in a set without a PW card to go alongside you're basically asking us to tell you why he shouldn't be in 6/8 stories or otherwise where he should have been.
Before Origins (which kind of resets the clock) Jace appeared in exactly two stories, Worldwake (where he blows up the Eye of Ugin) and RTR (where he's more central and becomes the Living Guildpact.) All his other pre-Origins cards are from core sets. He hasn't been in the storyline much at all until recently!
The fact that people disagree whether or not a character is being used well in fiction coming down to a difference of opinion on the subject without an objective conclusion shouldn't surprise you this much.
I haven't ever once argued about whether he's "used well." I'm specifically arguing with this factual claim. If he's overused, if he appears in storylines where he doesn't make sense, then someone can point to those things and establish it. That's what doesn't happen in this discussion because the response to Jace is an emotional reaction to the concept of the character, and the specific complaints like "he's everywhere" are backfilled to justify that reaction.
But, okay, if you really insist that hard on continuing this, please do explain to me why "Jace and Liliana knocked boots" makes Jace indispensably vital as a character and contributes more to the rich tapestry of Magic meta-narrative than just, you know, not having done that at all and doing something that wasn't dumb instead.
See, this is exactly what I was talking about earlier: you asked a factual question, I answered it, you responded with this strawman instead of just engaging the discussion. You have to argue this made-up stance where I said that Jace is
amazing instead of the actual one where I said that given the narrative setup they've designed, it made sense to use Jace in a specific block. No, nothing about Jaceliana is all that incredibly compelling or whatever, but it's the storyline they set up and have worked on telling, so given that it's what makes sense to leverage when they want to involve one half of that pair with the storyline the other half is already in.
*I also find it hilarious you have to have this conversation often enough that you've begun to stereotype "Jace Haters" as a sub-classification of human beings, and yet still somehow insist he doesn't have any popularity issues.
This is just one manifestation of The Reddit Complex where you have a ton of really loud, really angry people who post on a very popular internet website but are completely unrepresentative of the actual fanbase of their particular interest. If you look at these enthusiast Magic communities you have a lot of people who think Kamigawa is awesome and whatnot because they're a very specific niche of invested players. It's obvious there are a lot of people in this crowd who have this intense knee-jerk negative reaction to Jace, it's just that it's this tiny set of people compared to all the customers who actually like the character.
I guess you don't agree with me that having a giant card split over two looks ugly.
I mean, you push them together and it literally just looks like a card.
Tamiyo is one of the booster images, so I'll be extra upset if she doesn't get a card this set.
We got booster images?
