Cinccino's Bullet Seed was a 2HKO on the Togekiss. It used either Nasty Plot which went to waste or Air Slash which almost fainted my Belle. It then proceeded to Rock Blast Noivern I believe. Or my beloved Vileplume Maleficent shot it down with Moonblast. Crawdaunt destroyed Archeops, Gliscor and Talonflame with STAB Adaptability Mystic Water boosted Aqua Jet. Toulouse the Sylveon 2HKOed Mega Altaria with Moonblast, while it could do nothing back.
It was the easiest leader so far, honestly. Too big of a water priority weakness. She was supposed to be defensive too, but how are you going to be defensive with Archeops, Talonflame and Noivern?
