The prices of cards in this set are far less likely to hold their value than cards from other sets. The cards' value is high only because of the incredibly low supply of the cards in question. Of the rare and mythics worth more than the MSRP of a pack, how many have seen a reprint? Only 10%-20%, and all were only printed in sets before Magic's boom during the RTR period.
Furthermore, very, very few of the high value cards see competitive play, a marker of the ability of a card's value to withstand a reprint in the long term.
Does anyone honestly believe that filter lands see more play than shocks? The price of shocks is so much lower than filters because shocks were reprinted in massive numbers in RTR block, whereas the filters were only printed (outside of the Expeditions) in the original Shadowmoor block 10 years ago, when the player base was far smaller.
I'd be curious to see where prices are for this set in two months, because I'd be shocked if the EV of a booster box is anywhere close to where these calculations peg it before release.
EDIT: Added image.
Yeah, and that'll be a major discount over how much they appear for on eBay.
Unclear if they are only in the special product, or if they are also in booster packs.
They will be available on October 3, 2018 only in the "Mythic Edition" set from Hasbro Toy Shop for $249.99. The product includes 16 GRN boosters and 8 "Masterpiece Boosters". You're guaranteed to get all 8 Masterpiece cards, but it's limited edition.
EDIT: Added Liliana and Ral.
Marit Lage is a token.
I'd far prefer Proliferate to Evolve for the Simic. I hate how they made the Simic mechanics be some derpy +1/+1 counters theme both visits to Ravnica so far.
It's a GW guild mechanic, so, no chance.
I hope red/BR dies a slow, painful death in Standard after rotation.
I'd say the Jace is the least desired among the five by a healthy margin (Chandra is pushing $100, while the other three are between $50-$60). However, the prices will definitely appreciate with time, especially with this set, which seem to be in a higher demand than previous ones.
Also, the Mediation realm was artificially created, according to the story. Did Ugin create it? Or did another planeswalker predate him and create it?
If the card stays below $40 long term, I think that Wizards will continue the same practice going forward. $40 and lower is reasonable enough for a high-demand mythic in Standard as long as they don't make future BaB promos staples by any measure. If anything, Wizards' experience with Nexus of Fate only proves that such a practice makes the promo highly desirable and will serve to move boxes even more in the future.
As far as the people complaining about it, I highly doubt that the vast majority of those individuals actually want to purchase a playset of the card to be able to put it into a deck. Those of us who wanted to play the card knew it immediately after the card was spoiled (I know I did), and did everything they could to acquire the necessary copies of the card as soon as they could. Instead, the majority of the outcry on the issue comes from the perception that players may find it more difficult to play a certain deck in Standard if they so desired. No one likes being told they can't have something, even if they don't necessarily want it, especially when it comes to MTG.
I'm not saying that there's nothing wrong with the strength of Nexus of Fate or the BaB promo system in general, but that it isn't as clear cut as many are making it sound.
