I posted a topic like this quite some time ago. If I recall correctly:
-Protect/detect, makes slaking lose a turn
-swagger, especially on a special sweeper
-trick with choice band, that's murder
-mirror coat/counter, I hate it when milotic uses it
-sheer cold/horn drill/guillotine/fissure, 30% accuracy seems like 100% in BF
-explosion, too powerful
-endure/flail, sweeps my team when unable to counter it
