For me, the hardest Elite Four member was Malva. All of her Pokémon were quite difficult to take down, but the most challenging would probably have to be Talonflame. This Pokémon was extremely speedy, and had a lot of powerful moves in its moveset, including Brave Bird, Quick Attack, and Flare Blitz. With Brave Bird, it was able to take out my Blastoise and Espeon in an instant. Thanks to Flare Blitz, it had the chance to defeat Chesnaught, Dusknoir, and Scizor. Scizor was able to survive for a tun, surprisingly, but Talonflame had it finished off in an instant with Quick Attack. d: Her Pyroar was also pretty tough. It was able to get through many of my Pokémon simply with Wild Charge. To finally defeat Malva, I had to rely on a lot of recovery items.
