Keith AmmannI've been vocal in my frustrations with Spelljammer and Planescape, but I have to say I'm consistently impressed with how good the writing is in Mythic Odysseys of Theros and how interesting the monsters are, both in concept and in design. WotC caught lightning in a bottle with this one.

Dave Clark@KeithAmmann those three MtG books had great monsters, fun subclasses-backgrounds, etc
I didn't like the adventure elements from any of them, but the rules content was amazing
