You EX with Sycamore first, then Brendan, get rid of On Type bonus parameter. And allow both physical and special damage always in the parameters, should fix it easily, you can just add some extra HP instead. I guess the sync kills because you don't heal Sceptile from Discharge or something, he can does use it only once sometimes.
Otherwise there are other easier options, toxic stall with Sycamore, Lucy and Viola debuffing Sp.Atk. Pick status special parameter that allows status to do more damage through mitigations, then pick all the possible shields, filters and HP except for status immunity and it will be a walk in the park tanking Hau attacks and seeing Toxic doing huge numbers as it barely damages your team.
