One other subtle but funny joke: on Infernal Spawn of Evil, the word "Demon" in the card type line had been crossed off and replaced with "Beast." That was a joke of the fact that, at the time, we had stopped using Demon on cards and replaced it with Beast

To get a more concrete answer, use other formats you like as a baseline official Limited sets, other cubes, or even Constructed decks
While I still have some reservations, I find the D&D crossovers a lot easier to reconcile with Magics aesthetic (as I likely will with the Lord of the Rings set, and I am sure I would have were this set of precons focused on Warhammer Fantasy Battles, or even Age of Sigmar)
These sets brought in new Pokemon and gameplay mechanics, keeping the game fresh and exciting for players
