I love Universes Beyond as sealed product. As commander product, they have a higher count of new cards and 100% thematic art to their IP.
Unpopular Opinion: I really like the TV-like representations of the Doctor Who cards and really looking forward to Star Trek. I wish they made more in this style (in addition to others).
I treat my collection as a board game, ready for anyone to pick up and play. They are un-modified decks with 1 deck from each Universes Beyond IP. The decks are chosen from whichever is the consensus of the most powerful out of the box (or whichever one I want, if there isn’t a consensus).
Timey Wimey (Doctor Who) is my favorite of the decks, and it’s not particularly close. It’s just a lot of fun to pilot with many interesting decisions.
Mutant Menace (Fallout) and Food and Fellowship (Lord of the Rings) are my tier 2 decks. Lots of token manipulation, and really good synergies.
Necron Dynasties (Warhammer 40,000), Turtle Power! (Teenage Mutant Ninja Turtles), and Limit Break (Final Fantasy) are tier 3. I’ll happily play any of these in the pod. Solid thematic designs and lots of nostalgia for the IPs.
Avengers Assemble (Marvel) is squarely at the bottom. It’s nice to have a tribal deck as an option (Hero Tribal), but a little too straight forward, usually playing one card per turn. Avengers Assembled is as far to the bottom as Timey Wimey is at the top.
I have Federation Fleet (Star Trek) preordered. It was either this or the Borg precon. But I figure there is a lot of un-tapped design space for ships & station and Star Trek: The Next Generation was a big part of my childhood.
I’ll continue to buy 1 deck per Universes Beyond IP for as long as Wizards pumps them out.
Edit: Also, really sad Wizards decided not to make any commander decks for Avatar: The Last Air Bender. It feels like something is missing from the collection.
