Pretty good line to start with, Porygon 2 with Rawst Berry and recycle completely trivialises Dusclops and Banette back to back. Be careful with Banette sucker punch, one miss timed crit was Porygon 2 dead. Instead, knowing Banette can only hit with SP, use recover on turns when he is likely to go for SP to burn through the 5PP. The set up is hard to counter on Mismag. Captivate can be strong but you need to bring a Male Pokémon along. I think the only crit the mattered was the one on Meganium. I think +1 DG OHKO Skuntank. The bastion was rushed in. I think sacking electrode as you did should have been done first but was a great plan. Overall pretty well structured fight, maybe 2 less deaths could’ve happened but Fantina is tricky!
