As someone who played since early 2013 I can say that I've enjoyed every single format of Yugioh since. Sure there were times when my favorite decks got powercreeped and were less viable than previously (Geargia, Fire Kings) But in the end I've always found new decks that were as fun to play as those that came before them. The main attraction of the game to me is how its constantly in flux and that nothing ever stays the same due to the banlists and new card releases.
Even Pendulum is something I actually love the idea of, compared to most. Heck, Pendulum decks have been super weak since their release. Sure Qliphorts and PePe's were strong, but there were always decks that competed on equal terms or were better.
Yugioh is simply an amazing game, though perhaps my thoughts would be different were I to actually play the physical card game...
