Have things gotten so powerful that people forgot about Baneslayer being in a format alongside things like Eugene and what have you?
Quote fromIn the end as the crossovers become money makers it is far more likely that Magic will be an IP licensing vehicle more so than it's own thing. Companies don't stop when they make money and Hasbro/WotC see just how much they can make by pushing this out. They'll push it until something makes them stop either no more money coming in or, much like with loot boxes, regulations get thrown in and I don't see either happening any time soon with this.
Companies squeeze out as much money from something if sales are any indication of such. Which is why we haven't been seeing settings like Kamigawa or Ulgrotha as main settings lately since their respective inceptions.
However, I'm sure that if they were to one or both of those two back sales would be wild. (Although you could argue that Innistrad is the lovechild of The Dark and Homelands but I digress).
The consumer base is very fickle; I don't think they even know what they want. A lot of this is driven by emotion. That also holds relevance: What is important to you may not be important to someone else. You don't determine what ought to be "standard" in Magic in terms of how or why things get played/bought. All you can do really is play along and choose to opt out when able. WOTC is easily and undeniably playing into the financial reasons for this. They know people will buy it for the sake of having something in pop culture represented in MTG form.
Tired argument but it holds true. So who knows what will happen.
P.S: D&D is going to be a super popular set because of its tie in with D&D and that player base. It will probably be one of the best selling sets of all time. Watch.
