Alright, post rotation, I'm having difficulty finding a deck that is both enjoyable to play, and has a fair chance to win (~50% ish).
I have tried to play Gardevoir ex and Miraidon/Regieleki, but my god this community latches on to the most BORING mechanics.
I have tried lost box with and without Giratina, Magnezone ex, some memes with Wugtrio and Gyarados from PGO, and Dialga VSTAR. None of these decks are fast enough to outpace Gardevoir and Miraidon, so they just lose 80% of the time.
I like Arc/Dura, but the two best decks run zero special energy, so it seems pretty pointless to be honest, and even with the new addition of Vulpix VSTAR, I really believe that's only good in competet
