My approach has been have the maindeck largely preboarded for the creature decks and then pick a few key decks to target post board that have high impact sideboard options for the matchup
Every turn there's another Ascension trigger, another Nursery token, another Chocobo getting bigger, another land doing something it shouldn't be doing
Youre much better off using that Stifle on a fetch land and fighting them before they go off
But it was also around the time that Hasbro / WotC was in some hot water (can you believe it?) for their brief changes to Dungeons & Dragons Open Game License, so goodwill from a crossover was likely overshadowed, at least on the internet
I don't believe anyone has posted pictures publicly online though
However, the cards are legal in Modern, and of course Commander
