Even is you dont want to use it as a pure entry hazard layer, you can use it as a bait. Lure a trapper in, Volt Change out, and try eliminate the trapper before it switches.
Shandera: The only thing I can think of that will definitely take it out is ScarfTar.
Magnezone: Your own Shandera, or a Dugtrio.
Other Shadow Taggers: IIRC they're all Psychic, slower than Shandera but bulkier, so maybe we need a BandTar here.
It's impossible to cover everything. D:
