As for Dragon, it's a decently common weakness in ubers but like I said, Dragon Pulse as STAB is very lackluster.
Its coverage options are not very cohesive. It gets either Sunsteel Strike or Moongeist Beam depending on which form it starts as and I guess its ability might help scoring important KOs with those.
Then it gets random stuff like Power Gem (good for Yveltal who otherwise walks all over it) and Signal Beam (its best option against Arceus-Dark... actually just switch out if you face it lol).
It has a number of good setup moves but with that defensive typing and mediocre bulk it'll never get the chance to use them.
