Substitute->Disable->Substitute means it can get a free KO and substitute against most teams, which allows it a huge number of sweeps
Alternatively, the Perish Song/Protect/Sub combo beats literally anything that can't deal more than 75% to it and isn't ghost type
The only proper "counter" to all of its sets is to not let it mega evolve and then switch out, because it almost certainly will find a switch-in that gives it free set-up turns.
