It's not quite on the level of The Taken King or Forsaken, but Shadowkeep feels like a major step forward for Destiny 2. It's a promising starting point for the game's third year, and for post-Activision Bungie. I've thoroughly enjoyed the 100-odd hours I've put into it, and I'll easily triple that play time in the months to come.
My latest match was textbook CCG fun: I managed to barely scrape by in an unfavorable matchup, only to win at one health on the back of a few lucky top-decks on my end and two weak evolutions from my opponent. In that brief moment, I was over the moon about Shadowverse, and sometimes that's enough.
