For those of you who wondered what Fubuki was doing, she was trying to obtain a x6 Sp. Def against Spiritomb (which Shadow Ball reduces Sp.Def upon hit). She was essentially banking on consecutive friendship dodges in order to buff up to where she could pray she survives a OHKO from Cynthia's Roserade. Facing against a Sword Danced Garchomp is easier to live than this fight.
For those of you who don't get it all you need to know is that Fubuki was playing three different gacha games at the same exact time trying to defeat one of Cynthia's Pokemon.
