Ah, thanks for the help with Skarmory. As for Dark Pulse, I kind of just randomly chose that move. I was testing out different stuff, to see how it worked. That was somewhat of an untested team, so the Pokemon weren't perfect. I probably should have used a team I knew I had better chances with.
Oh okay, gotcha. Well, Dark Pulse is a decently cool move for smacking MegaMetagross and Mew, but I think depending on your set (was it Life Orb, offensive support, or something like that?) you might wanna be carrying some othe moves. So, if offesnive support I think Thunder Wave/Taunt/Thunderbolt | Volt switch / HP Ice | Psychic is generally preferred because otherwise things like mega Venusaur and Amoonguss and possibly AV Conkeldurr wall you (if not carrying psychic). HP Ice for things like Garchomp and Altaria. Paralyzing Mega metagross is huge so you don't always need dark pulse. Mew should be taunted all the time too so I think the main psychic types you hit aren't exactly things that want to take Thundurus on anyways. That's just my two cents however, I'm sure others may think differently
