I didn't play much on February's Kc Cup but I have to agree. My 1st cup was November 2018 and even then I was still a little new collecting cards and there were a lot of diverse decks when I started on Dlv. 3
Like February was the AG takeover and I found either AG, Koaki, or Yubel. I think Konami made a mistake bringing it back April instead of waiting until May before World Championship.
