Not too bad for a stage 1 and the type...
HP is OK for its type, and passive helps against confusion, the most annoying SC (IMO), but Thick Skin / Clear Body etc. are even better as they prevent all SC's.
The first attack doesn't require coin flip for sleep, so it can be abusable to some extent (Insomnia / Thick Skin / Clear Body etc. =o=?).
But the second attack is just your basic ex counter, however the chances are you'll probably get 1HKO'ed first by a stronger ex.
1x RC is pretty good for a 80 HP stage 1, but weakness to itself is the worst, at least it doesn't have any self damaging attacks...
6/10 - good sleeper and decent ex counter, but that's basically it, unless you combo it with some other things...
