No way. It misses a lot, and you have to be at a higher level. It is way too risky, as you said, as it has a 30 percent accuracy. Also, with Camerupt's only ok defenses, if it misses against something super strong, Camerupt is dead a a doorknob. Even if you are a higher level, there are much more reliable moves to use, like Earthquake, Flamethrower, Rock Slide, and more. Also, Camerupt is way too slow to actually hit Fissure before dying to a strong attack. I hope I've helped!
