It's more /tg/ than /v/, but still partially /v/ - Cardfight Vanguard.
From release through G-era, I loved Vanguard - it was one of my favorite games. I have fond memories of sipping some tea, listening to some music, and spending entire days playing against people on Cardfight Area. And then the first reboot happened.
It wasn't enough that it was a "rotation" either - the new V era cards had bigger numbers, the Imaginary Gift mechanic, and were a big increase in power while also taking most of the mechanical complexities that gradually grew over the first few years of the game and throwing them out the window.
Eventually, though, V era began to have interesting mechanics, Premium (equivalent to MtG's Legacy) began to have players, and they even released a Duel Links-esque mobile game that, while being simplified Vanguard, was still pretty fun. The game wasn't quite how it was when I loved it, but it was still a fun game.
A few years passed. The mobile game died. Another reboot happened - D era, bringing with it more radical changes than the V reboot, including consolidating the 24 Clans into 5 Nations (they were already part of these Nations as a lore thing, but now the number of actively supported strategies and mechanics is massively reduced), adding one of the swingiest mechanics a card game has ever printed, and adding a V Premium (analagous to Modern) that stole a bunch of the Premium players.
I miss it. Sometimes I solitaire G era decks against myself.
