Role Identification: Aero Dako is like, Pheromosa, but better. It has access to a large movepool to hit stuff with and Rock Surge, which lets it set up a new terrain that boosts the power of its Stone Edge/Rock Slide by 1.5. Also, it is not defensive that much, it is rather frail, but it is at least able to hurt other Pokémon trying to hurt it using the other effect of Rocky Terrain, where a Pokémon loses 1/16 max HP, an Iron Barbs effect, if they use a contact move. The typing is specifically chosen to just destroy all things, as it is super frail and would die to a lot of stuff anyways, especially if it is to be placed in a meta in which even walls have a huge attacking stat.

Role identification: Hmm, lets see here. Wild Charge Stone Edge Brave Bird filler. Really all you need. Mega Aero Dako is super powerful, with a huge attack stat of 160 and going sonic speed with 170 speed. It's really self-explanatory, just give it an attacking moveset and destroy everything.
