Technically, it's just the first card to create a specific non-creature token that they have printed a token card to represent.
Anyway, yeah, bad card is bad.
Right, I said as much in my post. There have been other ways of doing similarly before, but according to all the things I can find it was strictly incidental. Things like "put a token that's a copy of target [permanent type] into play". This card is just boss because it's explicit in it, and I would really love to see more cards that go and do likewise.
I think it's telling that the card I'm most excited about in this set is Karametra's Favor, a card which forms a two-card combo to cast Diabolic Tutor with a small upside. Wheeee.
Karametra's Favor + Demonic Tutor?
I suppose you could always tutor for the missing half with Shred Memory… secret tech is secret! Sssshh
