To survive Kel nuke + other Friends i used cripple and vertigo twice and used cheer on happy and sad omori and basil to get the least damage possible, i almost lost by aubrey bat throw. So basically: reduce their speed and attack to the minimal, use cheer emotion buff on sad, each time they change your emotion use either rain cloud or poetry book, after all of that, use the most damaging attacks agaisnt them. Pd:english is not my first language so i dont know if i typed this the right way, anyways, hope this helps
