The Normal type, always blessed whit useful options, has now access to the most powerful move whitout drawbacks in the game, Boomburst, which has an insane 140 base power whit 100% accuracy. Being a sound based move it can also bypass Substitutes.
Good Boomburst users. Porygon-Z and Sylveon deserve a mention because of their abilities, Adaptability and Pixielate respectively. Adaptability makes Boomburst a 280 base power move, able to 2HKO Assault Vest Tyranitar in the sandstorm after a Shell Smash, while Pixielate turns Normal moves into Fairy moves, giving to Sylveon's Boomburst STAB and nice SE coverage. Pixielate is also nice whit Rapid Spin(Scrappyspin 2.0). Recover is also a nice gift for more defensive Sylveon's sets.
Everybody of them can(and should) run Shell Smash.
Does status moves act twice? If yes, here is the best Shell Smasher in the world. If not, she is still one of the best ShellSmashers. Her Extreme Speed is actually more powerful than Arceus' one whit the same amount of boosts, and break substitutes, sashes and sturdies. Earthquake blows most steels away, same for Ghost types and Crunch/Sucker Punch.
The previously mentioned Belly Drum+Extreme Speed Diggersby. It has 1856 attack after a Belly Drum. Does this need other explainations?
Furfrou has the awesome Fur Coat ability, which doubles his defense. His support movepool his lacking in the standard metagame thought. This is not true in STABmons. In facts, he gets some goodies such as Rapid Spin, Recover, and Heal Bell, as well as Whirlwind(it already had Roar, thought). Access to U-Turn makes him a reliable pivot. And goddamn his fur is just so cool.
