I think the one thing I would've liked to see more of in the list are summon cards: if you look at our commander options, Tidus, Yuna's Guardian and Yuna, Grand Summoner, both clearly work exceptionally well with the new summon creatures like Summon: Valefor as Tidus can remove lore counters to keep them around longer and Yuna can pump up creatures when the summons die, and that's a unique new game design space that would differentiate the deck from more generic +1/+1 Counter lists out there
Be sure to call ahead to preorder one, and while supplies last, you should be able to pick one up
Some of the decks Ill talk about can compete with Felidar Guardian or Treasure Cruise, and some probably cant, but thats not a huge concern to me
Elenda can populate the board with a great deal of tokens in short order, especially as her token production is tied to her power rather than the quantity of counters on her a Blackblade Reforged can help a lot here
Gogo's ability targets an activated or triggered ability that is on the stack and creates one or more additional instances of that ability on the stack
