to A
+ Has potential to sweep 70% of your battles only by setting up a quiver dance.
+ Great special bulk, which allows it to set up on a lot of mons.
+ Flame body is a cool ability that can create set up opportunities against physical oriented mons too, and swarm is also decent.
+ Even though it doesn't get a lot of options, all it needs is quiver dance + dual stab to win most games. Other options include hurricane or a good hidden power.
+ If you look at what's left: Steel gym, psychic gym, Ren, dark gym, Aelita (hurricane is nice) you'll notice that volc has a great chance of destroying them.
- Not really useful against any gym leader at the moment since it only evolves after Angie (unless you want to level it up and bring it down with common candies), which it's biggest flaw.
- Really hard to get in the mystery egg (but it's REALLY worth it)
- Terrible physical bulk, you might die to anything with rock/water coverage before you can even think about clicking quiver dance.
