Ill consider it a success if the working group is able to come up with a manageable number of snappy, descriptive names to describe the groups of cards that I see in the silver-bordered cardpool
But more importantly, it has some issues fitting into most prowess and spellslinger Commander decks since they tend to be either Izzet or Jeskai
The rarest and most valuable of the group is the iconic Black Lotus, widely considered MTGs holy grail card, which is joined by Ancestral Recall, Timetwister, Time Walk and five gemstone-themed Mox cards: Emerald, Jet, Pearl, Ruby and Sapphire
On top of that, their Pokmon are incredibly powerful and generally designed to have a strong cool factor
The adjustments over the past few years have addressed many of the largest pain points, particularly around the value disparity of collecting cards through Draft versus opening packs, but we still have some areas to iterate on
I cannot speak on flavor or anything else too
