Choice Specs is completely outclassed by Life Orb on something with perfect coverage in 2 moves.
Trick isn't even worthwhile, since Munchlax will still beat Misdreavus and be healthy enough to do more. The only advantage would be allowing something weaker to set up, or if you're using a bulky set.
Barely OO, but I'll list it I guess.
Also, I added EM's suggestion.
